One aspect of undervolting not mentioned in the video is heat in the room. During these warm summer months, dumping even a tiny bit less heat to the room helps.
@@Nicc93 My room got to 38c one day last summer here :). Also most days during summer my bedroom didn't drop below 30c. EDIT: I'm talking all day and all night my room didn't drop below 30c lol.
I undervolted my 4070ti and reduced the power consumption by 20% with actually a 2% increase in performance. Main reason was because UK electric is too expensive so trying to save money somewhat.
I bought my "MSI GTX 1080 Ti Gaming X 11G" on release back in August 2017. Ran it stock for the first year then got myself into undervolting (never had undervolted before) and once I had tinkered enough and got very used to it. I even undervolted the GPU my sister has too (she has my old MSI 1070) Been running mine at 1848MHz on the core @ 900mv with 6106mhz on memory (+600mhz). Pulling about 180-200 watts on average during full load. In my case I dropped about 10 celsius on max load with these settings (sitting at rock bottom 60 celsius now instead of 70-71) Also pushing the memory has been very favourable for the pascal series GPUs and I think that could easily minimize or wipe the slight performance loss for the undervolt entirely. Love your videos!
When i still had a 1080Ti (Gigabyte Aorus Xtreme), I could run it 2000mhz @975mV with ~185-205W powerdraw compared to stock 2050Mhz boost it could gain at 250-280W powerdraw. Though i was also custom looped
DDR6 on RTX20 cards clocks up well and can bring the card to life. When I got my (current) 2060S I ran a basic OC to see what's what, I gave it about a 7% OC, but I was really confused because with the OC my synthetic scores went down. Then I played with the memory, I got the memory up by 1000MHz to 8000MHz and my synthetic scores rocketed up from top 46% to top 19% at that time with both sides done. I ran it unbroken for a week and it was totally stable, not a single crash. I mostly run stock now because I really don't need the extra performance at this time but it's nice to know I can get a bit more life out of this when it starts to creak then when it's on it's last legs UV it to buggery to drop it down to a lower tier performance and use it as an enhanced video adapter in another machine (or maybe in my main rig for some extra video out ports in a x4 port) for years to come.
@@darthwiizius Oh yeah when messing with the memory: Just do back to back benchmarks and compare the scores and when you start seeing smaller jumps or the score goes down, revert it once to be safe. A lot of people tends to push it till just before they see artifacts, which will offer similar performance to something closer to stock and more strain.
@@MrBluePoochyena I see, I'm just praying that the memory doesn't fail sooner or later since that's what mainly has been killing these older pascal cards.
@@mr_cryzler34 If i had ran the car aircooled, I wouldn't even have been able to reach even close to the 2000mhz clock with 975mV, as the good old more heat the card produces more voltage and power it consumes.
I always think of buying used gpu then undervolt it but afraid to do it. Now I understand that it doesn't really affect the gpus' performance that much. Thank you for this wonderful video!
The 1080 on undervolt comes at an astounding average of 70Ws at the mythical 847mV while only losing between 7-11% of the brute performance, I say it's very worth it if necessary (Tested on a 10100F rig so it can very much vary) Edit: Grabbed a Moderately Priced 5600X myself since my previous rig commited delete Sys32 and the max power consumed from the UV 1080 was 115W in CyberPunk 2077
@@vinylSummer It's a very well known frequency from back in the day (2017, back in the day, I cant believe I'm saying that) where the card retains great performance while also dropping a noticeable ammount of power. 2016 Nvidia moment
Also if your GPU is quite enough to reach your refresh rate, don't hesitate to use VSync or framerate cap. It can reduce power consumption in less demanding scenes of game. Combine this with High graphics instead of Ultras and you get good visual fidelity with good economy😊
Undervolting went great for me... I messed with my 5700 XT Gaming X and upped the power limit by +30, a stock, non-undervolted card could consume upwards of 300 watts.... a slight undervolt from 1200mv to 1140 not only lowered power consumption by roughly 30 watts, but preserved the performance boost gained from raising the power limit and lowered the temps by ~10 degrees. These sorts of tweaks really make the 5700 XT undoubtedly one of a few, if not the best bang for the buck gpu you can get atm.
14:28 The graph's labels are switched. Other than that, this is a great video to show how undervolting can minimally affect performance for massive decrease in power draw. Great work.
Undervolting is amazing! I own a RX 580 (2048sp) and it used to consume around 150-180W in most games at default voltage and clocks (1150mV and 1284Mhz), but after a 150mV undervolt it managed to use only 100-140W and the temps were way better, going from 75c to around 60-65c, making less noise and less heat.
@@raresmacovei8382 if amd driver says it's a RX 580 2048sp, then it is a RX 580 2048sp. And before you say anything: I know that it basically is a RX 570
Undervolting and power limiting are insanely awesome ways to get more power savings. I managed to drop by 3070 Ti from 290W to 220W while losing barely any performance in any game by overclocking the balls off it. It was awesome.
i undervolt then limit my tdp as far before lowering performance from stock. right now my 6900xt is running at 198w full load and it still performs 3% better than at stock @ 265w. (these are core TDPs, board power is higher, but i also lowered that significantly on my gpu, but i have no way to measure it that i bothered to... don't feel like measure at the socket)
I mostly use my 3060ti at 1410mhz and about 0.695V. It uses only 100-110w even in 3dmark which seems fairly power heavy while performing like a 2060. And sub 100w in games
Personally I find it a necessity to undervolt for longevity and temps particularly with AMD GPUs. From the RX 570 to the RX 5700 XT to the RX 6800 XT, every time I let them run at stock, they get quite hotter quickly and draw a lot of power (even if the efficiency of AMD GPUs have become better over time sans the RX 7000 series). Doesn't help that as someone in a tropical country with no aircon, the GPUs I run can actually at times hit throttling temps even with some cooling. With undervolting (usually at 1.080V or lower depending on silicon quality, varies between GPU ofc) and slightly reducing from max frequency, I draw less power which can slightly help with heat as well (not much here in my country but would likely benefit others with lower room temps), maintain more ideal game clock speeds for some more frametime stability, and barely notice a performance loss.
This isn't a good perspective. You can always make GPUs more efficient with an undervolt or adding a slight underclock also. This has always been true, regardless of the state of the market.
Try turning the memory speed up on the RTX2060, I do that if I need a few extra frames and the DDR6 can be pushed quite a bit. I ran my 2060S memory at 8000MHz for a week once and it worked fine.
Living in Texas, this summer has been brutal. Perhaps an undervolt can ever so slightly make the heat more bearable, and for losing negligible performance I'd say if you can undervolt there's no reason not to.
As a 40 series laptop user, I can confidently say that the 40 series can be undervolted without sacrificing any performance, at least judging from the Time Spy numbers. A typical stock 4080 laptop can do just shy of 19000 in Time Spy, but the main limitation of this performance is not its Core clock speed, but the VRAM bandwidth. By locking the clock speed to 2340Mhz at 0.85V and giving the memory a +1150Mhz overclock, I am able to get a score of 19355 in Time Spy, while the power consumption is reduced from the stock 175W to just over 130W. In scenarios where I don't need all the performance that 4080 laptop will give me (i.e. in Apex Legends), I've set a profile in Afterburner to underclock the GPU Core to 1755Mhz at 0.7V while leaving the memory at stock clock speeds. With this setting, it got 15166 points in Time Spy while using just shy of 90W, and in Apex Legends it averaged out at roughly 85W, and I am happy to report that this setting yielded me great reduction in fan noise while keeping the game running at 2k max setting 180fps+.😆
I have a rx 6700xt with an undervolt and overclock 1080mv and 2600mhz went from 80c stock to 65c, and now in summer I underclocked it as well 2133 mhz 1060mv and it reaches 60c but its always on lowest fan speed, lost about 8 fps but the watts went from 180w on undervolt and overclock to 110w on undervolt underclock. Its a great card honestly
imo the biggest upside of undervolting is being able to run your fans quieter while keeping the same temps aswell I got my Rx 6700 down to 100-120W so now my fans run at 1000rpm at 65c
Great video! I had an RX 570 for 5 years and was able to undervolt it while also overclocking it and it was completely stable the entire time. Probably the best GPU experience I've ever had, I got it during a promo where it was $120 brand new with DMC5 and RE2 remake steam codes included. Those were two games I was already going to buy, so it was essentially a free upgrade. Crazy how the market has changed since then. The only reason I'm not still using it is that I wanted to give it to a friend as an upgrade.
I had a 2060 Super that I undervolted from 180w down to 140w with no performance loss. Then I upgraded to a 4090 and did the same thing. Down from 400w to 250w, albeit with a small performance loss (
You can always save even more power if you're willing to drop clocks a bit also. Shave 100 MHz clocks of your GPU and you'll be able to undervolt even more.
For Radeon users it is best to use the power (TDP) limit in the driver software (for supported cards) as the card will automatically under volt and adjust clocks as necessary. The clock speed will depend upon the load. So for some instances clocks will not drop. There are real power savings as this metric sets the total power draw of the card which I have proven the reduction with my wall power monitor. (I own XFX RX 590). Some real advantages over under volting manually are: because the card is controlling the voltage and clocks it will not hang/crash or become unstable under load, another point is that the Radeon software allows you to set the power limit globally and per app.. (you can create profiles)so for games that are less demanding you can have more aggressive power limits for them and for games that require more processing power you can have more relaxed power limits (the card will run higher clocks and draw more power). In my experience with the RX 590 which is designed 200W TDP (196W) to be exact when I set the power limit to -50% the driver software reports consumption of around 96 to 99 Watts which is also in line with the numbers is see on the wall power monitor (a reduction of 90W+). Nothing is wrong with experimenting but radeon power limits will be easiest and best for most people to save some power and not sacrifice much performance depending on the card load.
The other day I undervolted my daughter's GTX570 (you know...HOT fermi) because heating the room in the summer isn't a thing. Oddly enough, it worked. Managed to drop temps by 7 degrees and not lose any performance. Could also drop it more and lose just a few MHz. So it works on much older cards too. Also, for years now my trusted RX480 at 1.005v doesn't lose any performance while consuming only 75-78w.
In addition to Vega, the R9 Fury series is another great candidate for undervolting. They don't overclock much at all. You will be doing good to get another +50 to +100 on the core, and MAYBE with the right drivers (16.12.2 was the last driver version to support Fury HBM overclocking) you can get +50 on the HBM (Fury HBM steps up one level from 500 -> 545, but it is VERY RARE to get them to step up to the next level at 600). HOWEVER... they can OFTEN run at stock speeds with anywhere from -50, -72 or -96mv, sometimes even with a mild overclock. This drops temperatures and power usage to GTX 980 levels.
I have a Vega56 I’ve undervolted /overclocked and it’s awesome. Undervolted and on normal clock speeds it does about 110 watts. But on its max performance config it does 225 watts.
When I saw you dragging that voltage curve down the CORRECT way I just said "good lad", the amount of people that do it wrong drives me insane, esp bigger youtubers
I got an rx5700 running stable undervolted to 925mV. The core clocks are at 1860 and the memory is at 1850. Both of which are the max clocks on the radeon software. It consumes 130watts at most. It was even mostly stable at 910mV but I mostly play Bethesda games so I just leave it at 925mV for some breathing room due to the instability of modded skyrim and fallout4 games. Lol I tried swapping out the bios to get 150mhz more but it needed 100mV more to be stable and it increased the power draw by 40watts. It wasn't worth it for a 3% actual performance gain so I'm sticking to the undervolt instead. The amazing thing is that the Rx5700 performs on par with the 1080ti and you could regularly get it for under 150$. You can even get a Chinese refurb one shipped to any part of the world.
@@tanmay5570 yeah! I started with a chinese rx580 2048sp (essentially an rx570) then upgraded to an rx590gme( a chinese rx580 lol) now this rx5700 is my latest card and it's probably gonna stay for a while.
What I find to be easier is to max an undervolt on one profile and use it for everything that ISN'T a GPU bound game. Then, create a power profile to amp the GPU up to high performance when it's needed. When you go to fire up a game, simply click your OC profile and then the check button and minimize it. Now you have the performance you need when you need it. When finished, click on the low power profile and then check mark and minimize and you are back to sipping power. I cut my PC power bill in half (Literally took $20 a month off of the operating cost of this one PC). Granted if I play games nonstop all day everyday, this makes zero sense as you'd be in high performance mode all the time but for the average gamer and user it works well. Best of both worlds.
I have an inno 3d 2060 super and it's best to say the cooling system aint the best on it. Easily reaches low 80c. Undervolted it to around 950-ish mv. Now it's hover around low to mid 70c :D
Nice topic Iceberg! There is a proverb my great-grandfather used to say ''Bean by bean you fill your bag''. Well today you could say watt by watt you might not fill your bank account but for sure you could invest those 29 pounds into something else. Additionally undervolting, fps limiters, sufficient air flow, regular cleaning and maintains are some "inexpensive" ways to keep your computer parts cool and long lasting.
Undervolting RDNA 3/2 and Ampere/Ada GPUs doesn't really affect performance much (and even improves clockspeeds and frames in some cases) but I vividly remember having terrible 1% lows and stutters when even using the smallest undervolt with older architectures 🤔 Wonder what happened?
I discovered undervolting when I upgraded to my Red Devil 6800xt this spring since it's an option built into the AMD software - Like you showed, at a certain threshold it becomes unstable in certain games, but once I found that limit and kept just above it, I actually GAINED some performance because it reduced temps a bit, allowing it to overclock closer to the target I'd set for it! Lower power consumption for better performance? 100% worth the bit of time invested.
There's two aspects you kinda overlooked: You used Cards with good/sufficient cooling solutions (and I assume in a open or well ventilated case) and sufficient PCIe power connectors, but a lot of cards struggle with those. The RX 480 had some released with 1x 6-Pin (and then exceeded the specs for the PCIe slot to get power), some GTX 1060 had solid alu block heatsinks, the RX Vega was the posterchild for undervolting for temperatures and that's not even starting with all the blower style and/or OEM cards.
My room gets hot during summer making gaming a dread and if you don’t have an A/C unit, undervolting helps with the amount of heat been exhausted into the room.
Keep in mind that, before RDNA 3, power is not 100% accurate measured. Sensor is only for asic power if I'm not mistaken. So that 580 is not drawing only 130w, 6700 is not drawing only 160w etc.
My brother owns a HP GTX 1060 with a weak cooler and it throttled to around 1600MHz in less than two minutes. Now it runs at 1689MHz at 800mV at around 75°C. I also overclocked the vram by 340MHz so it performs 5% better and only consumes 80-85w instead of 110-120w. :)
I have undervolted a 6900XT and resulted in max power draw of 220W, 80-120W down from stock. FPS is nearly unaffected, but it also reduced core and hotspot temps by 20C. Similar story UV on a 5800X3D. 🎉
Just look up the similar Quadro or Firepro from the generation in question. They tend to run at a better compute/Watt ratio because companies look at that kind of thing. Not just for the power used, but to make sure that they will be able to cool the datacenters they put it in. In fact, get a Quadro because it might have a better bin of silicon.
Maxwell not really. I bios mod them cause i dont wanna tinker with msi afterburner. In any case. Drop the power limit and overclock them. On one side you limit its power while overclocking maxwell what it actually does is shift the voltage power table so in reality you are using the same stock clocks but a using less voltage per clock thus letting gpu boost peak at higher frequencies. What i did find is you can also undervolt the memory controller vía bios mod thus saving some heat and watts that can go to the gpu itself. Case in point i currently have on one of my systems a 980ti powerlimited at 180w and memory at 3200mhz (lower than stock). I would love to have a stock 980 to compare but i believe by benchmarks alone that its much more efficient. Like 10% fps to power ratio than a stock 980. Maxwell are crazy efficient for a 28nm design. If you keep them circa 1000mv mark they are awesome. A couple of years ago i also did have two 970s in sli, overclocked and power limited at 135w each and and those things were fast, shy of stock 970 performance and much more usar friendly noise and power wise. Regarding kepler... memory overclock can make a difference. Maxwell memory compression and newer algos did a lot of "magic" for efficiency and those are not present in kepler obviously. At least those where my findings using gtx 670 and gtx 760. God knows why the gtx 760 was able to pull like 1700mhz on those magic gddr5 memory chips. Also on all GCN and terescale ark card (on the amd side of things) you must try altering memory timings, there is free performance there if you fine tune it.
Undervolting is hard locked on Kepler (780/Ti) and Maxwell (980/Ti). You need at least GCN2 or Pascal (GTX1000) for software voltage tweak. Otherwise, your only option is a vBIOS mod.
Doing this in laptops is particularly useful, you get less heat which ends up throttling less and makes you get a more stable experience, and you stress less the AC or the battery
My Gigabyte GTX 1660Ti was pulling on average 125W on full load at 1000mV, 1900mhz core clock, while also reaching temps arround 76°C, it was really noisy aswell. Managed to undervolt it to 825mV, 1830mhz core clock, the temps went as low as 69°C, it still was a noisy mess so I had to set up a custom fan curve. So far undervolting has been a god sent.
Most people skimp on psus, especially those that use cheap as chips used gpus. Undervolting will lower the risk of house burning down - another positive!
Daily drive a RX 6600 stable at 1030mv (and I think I lowered the core 50mhz). Games draw 60-90 watts. I play older slow paced titles (think RE2 remake, RDR2, Snowrunner, SOTR) at 1440p upscaled to 4K at 60hz. Very happy how it looks, runs, and how little heat it puts out
if you own a Vega, always use HBCC in more demanding games. However your system ram needs to be really stable to do it, as if your overclock has any cracks in it; it will find it.
400/500 series that were used for gaming have discolored shrouds because of overheating. My GB 4G 580 didn't want to hit 1300 something boost clock because the VRM's were overheating. New set of thermal grizzly pads, MX4 paste and still. Undervolted to 1070mV while overclocked at 1400MHz Coreclock (don't remember VRAM OC). Card was rock solid at 1400MHz. In my opinion, those that mined have far less temperature cycles and stress on them. Would always prefer a miner one. MSI Gaming X 6600XT heavily undervolted while overclocked to 2750MHz (2500 Memory). Powercolor Fighter 6800 undervolted to below 950mV while overclocked to 2490 (had some trouble staying within the undervolt that I like while hitting 2500, so settled at 2490) and 2250 memory clock. All cards were ran under Linux at a locked coreclock in game. In my opinion, Linux doesn't like as high junction temperatures as Windows so coreclock starts to throttle at around 85C on the junction. TL:DR you can overclock these cars while undervolting.
Definitely UV is a must. I have a 1660TI that can easily consume 156W@1980MHz on stock and run at 85C+. I undervolted it to 775mV@1850mhz with +1000MHz mem clock. Now it only consumes around 73-75W and 65C max with performance loss around 8% max
My GTX 1660 Ti is running at 825mV since I bought it last year. Powe consumption in heavy games is 85-90 W most of the time, from 125-130 W with stock settings. I slightly underclocked the the GPU core (100 MHz less), but overclocked the memory from 6000 MHz to 7500 MHz, so the performance is almost the same as stock. Temperature also dropped in 5-10ºC.
Since i gained a quite nice boost on my rtx 3080 laptop by undervolting i am going to undervolt anything i get my hands on from now on. It´s essentially free performance, sometimes more, sometimes less depending on silicon lottery. Specially in powerlocked parts, the powerdraw stays the same but clockspeeds go up.
at the 11:00 minute mark i think you can do a better job with the graphics. you can increase the size of the blue bar to the size of the first red bar. this way we can clearly see that the red bar reduces more than the blue bar (in %)
Undervolting tamed my VEGA 56 to a max of 176 watts power draw at 1480mhz for the core and 930mhz HBM2. Still using this card since I'm only gaming on 1080p. :)
I'm not really that concerned about power draw and electricity bill but it's still fascinating to know how these cards hold up. What I do care about and advocate as to why everyone should undervolt is at 17:49!
I run heavily undervolted at lower clocks in most games because I rarely need my GPU to be maxed out. In return I get a much cooler and more quiet card. Modern GPUs are basically overclocked at stock and much more efficient running a bit slower.
I also have my 1080 Ti at 1875MHz coincidentally enough, albeit at just 900mV. Goes to show how results may vary based on silicon quality I guess. I also run +400 on the memory, which actually puts it slightly above stock performance when all's said and done.
It is absolutely worth it to undervolt, just for the temperatures alone. The 2060 in the video (with a bad heatsink) ran 10C cooler with the undervolt, without losing performance. I have a single fan 1660Ti running with -95mV. At the same noise levels it runs 12C cooler than stock, only losing ~1 percent in clock speed (not noticeable in games).
Undervolting tamed my VEGA 56 to a max of 176 watts power draw at 1480mhz for the core and 930mhz HBM2. Still using this card since I'm only gaming on 1080p.
I remember having to undervolt my 1080ti when it was dying. The card did eventually die and I foolishly replaced it with a 3070ti, but the 1080ti lasted a year or two longer.
My undervolted and under clocked RX 580's would burn about 95 watts and run between 50-60 degrees Celsius while mining Ethereum during the last boom. At one point I was raking in hundreds of dollars per day and burning very little power. All good things come to an end. All of my 580's were repurposed as budget gaming cards and have made many entry level gamers happy.
Hey man, what are your temps in the 1080ti with that "Rajintech" GPU cooler after a run of Heaven benchmark with max fan rpm? I own a blower card it goes over 70c with everything maxed out. I've manage to keep temps at a max of 57c in a run of heaven benchmark with a old 140mm 3700RPM fan at max speed pointing at the patetic stock blower cooler but its stupid loud, still better than the stock blower fan. The 140mm fan is just loud, the stock blower fan is loud and whiney. But I'm looking into upgrading to the same cooler as you.
Well, bear in mind 1) I'm in a non-climate controlled room, 2) I don't know what my ambient temp is, and 3) I'm not using a case. After about 10 minutes with the power limit at 120% and GPU clock at 1936MHz (boost only, no overclocking), the GPU is running at between 55 and 56 degrees. I don't know much about the Arctic 120mm fans that are installed, but HWInfo reports them as running at about 1500RPM and they are some of the quietest I've ever (not) heard.
"Running Cyberpunk on a Voodoo 2" this hits me hard. I remember upgrading from a 233MHz Pentium II to a 500MHz Pentium III and finally adding a Voodoo 3 insted of softwere rendering, i finally maneged to play Tomb Raider 2, 35ish fps, it was mind blowing...
I used to run my 1070 at 1000Mv, it could do 925Mv but one game of course didnt like it..then a second 1070 walked past my rig and power consumption of course is out the window and i run them cranked but with a locked 1025Mv, i still shaved roughly 30-40W off the cards so they run full tilt around a 1080Ti's PC but i get more performance..especially considering all the unsupported games ive played so far have utilised SLi and scaled very well, meaning ive been able to choose between 1080p 120-144 or crank everything to max, 16X SLI MSAA, SSAA. DSR etc fpr 4k 60, the more i load the cards, the more they wake up and give me solid 0.1% lows, in games that dont scale well, i still find the 0.1% lows remain absolutely solid so that is still an improvement, they peak in the high 50s due to my cooling setup but i then chose Doom 2016 and when i put it to 4k, almost scraping 60 until heavy action, both those GPUs were pegged the 4930K CPU woke up with them and the cards hit 68C, whatever that game did, it was stressing them harder than any GPU benchmarks i could throw at them! some cooling reconfiguring for the things did bring them back into the low 60s but considering i've saved money in the winter last year avoiding paying for gas and putting the central heating on purely as the PC can warm the room up for me, i think im going to be quite cosy this winter! Its amazing what old hardware can do today when overclocked, the sabertooth X79 and CPU for 90, same for each 1070 and the 32GB QC memory for 35 means for under the price of a modern entry level card at a tickle over £300, i got a monumental upgrade from a 4570 and 1060 3GB, chuck in the extra i spent on cooling overtime and its still cheaper than a 4060..and i got a whole PC out of it..Still playing 1080p high framerates, SLi helping to mask those dips under the monitors refresh rate. There are some games that of course show the platforms age, but it still puts up a good enough fight to keep on using it until i can afford an upgrade that will see through their limitations to make it worth it for me the longer i wait the cheaper hardware becomes and soon i'll have a 5800X3D and 3080, if threadripper wasn't dead i would use all of that memory bandwidth in a heartbeat and part of me will miss the gone era of QC memory platforms as i gained 35-42% gains from a temporary dual channel to quad channel configuration..and to think we don't see those improvements today from platform to platform..perhaps i may wait until QC makes its way back to consumer platforms..imagine an X3D Chip and QC support, perhaps it may be AMD's secret weapon if intel can step up in a big way..
Over the past few years electricity has moved from a thing I top up when the alarm warning goes off when its low. To something I think about daily. Its changed the way I use a PC. My main tower PC is only on a few hours a day now and Ive shifted my gaming habits to suit a mini PC.
I'd recommend trying to undervolt the core while OCing the memory. It tends to give just enough performance back after lowering clocks slightly to keep performance about the same as stock. I got a 2060 down to 145 watts while having basically the same performance as stock due to the memory OC.
I have a 3070ti and right after I got it, I undervolted it and dropped from always above 280w to always below 200w. I did drop the clocks from 1950mhz to 1800mhz but voltage from 1050mv to 900mv. Anyways, I didn't need all that performance as I only use it at 1080p. I didn't do it for a lower electricity bill, just for lower temps(about 80C all the time with 45% fan speed to 67C max with 31% fan speed). Very noticeable drop in loudness(almost as loud as a room fan at low speed to incredibly quiet that I have to put my ear right next to the case to hear it). Mine is the palit 3070ti version. I don't exactly know the name
why is it that the 6700 desktop variant is so inefficient? The laptop version (6700m) which I have does about 2400mhz at like 110w and beyond that it gets too hot mind you, but if I just run it for the first 10 seconds or so it can do 2500mhz at around 118w power and just in seconds its throttling haha my best is about 90w power and 2100mhz frequency, undervolted and overclocked using MorePowerTool
Undervolting rocks - it's been super helpful to me given that my room gets to 33-35C ambient during hot months (and no, air conditioning isn't an option). I currently use 1680mhz core and +500 memory @ 775mV on my 2060 when playing demanding titles - this cuts power to about 115w max. I've tested 1470mhz and -500 memory at 700mV recently - this cuts my power consumption to ~85w. I'll be using the 700mv profile in situations where performance isn't essential.
My RTX 3060ti is running at 0.756mV with clock of 1600MHz. Yes, you lose a bit of performance but it's incredible to see 90-115W (on full load) of power consumption on such powerful little card. I like to cap fps to not generate extra stress. I can comftably play RDR2 at 1080p mostly Ultra (with fsr Q) with super stable 60fps with gpu power usage of 50-85W. Also made a bit different preset. exactly 1mV with clock of 2000MHz. It's still a bit lower voltage from original while achieving higher performance. It took around 190W. You made me want to search for even lower power consumption on this little beast
I have no problems with electricity cost where i live, but i always undervolt my videocards for better thermals and less noise. Which is especially important for postmining cheap RDNAs (got my rx 5700 xt Asrock Challenger in April for about 150 USD)
I am running my RX 6700 undervolted and underclocked to 1090mV and 2400 MHz max, but overclocked memory to 2150MHz. Result is excellent temps, pretty stable(can crash sometimes on more demanding games, but can be upped a bit if needed for such games) and performance is the same as on stock settings. Power consumption is 120-130W (my goal is 1440p 120fps)
14:37 "RDNA3 is reputably far more efficient that previous generations" That couldn't be farther from the truth lmao. At best they match efficiency and at worst AMD dropped the ball and made RDNA3 LESS efficient. Good job Radeon group. Dissapointing as always
2:55 that's RivaTuner which comes shipped with Afterburner? It can be run standalone, too. At least that was my impression; please correct me if I'm wrong. Anyways, great video! Thanks for the inspiration; gonna undervolt my 2060 just a tad now…
I remembering doing this on CPUs on laptops back in 2018, until Intel removed this feature because it involved using SGX and there was a vulnerability discovered that required it to be locked to solve it

One aspect of undervolting not mentioned in the video is heat in the room. During these warm summer months, dumping even a tiny bit less heat to the room helps.
Glad I live in Canada :) my gpu pushes 400+ watts and it barely affects my room temps
@@Nicc93 My room got to 38c one day last summer here :). Also most days during summer my bedroom didn't drop below 30c.
EDIT: I'm talking all day and all night my room didn't drop below 30c lol.

@@GewelReal it's 12c here at the moment but then again it is winter time lol.
@@WyattOShea It's summer here. God damn you global warming! Warming the summer from 30°C to under 15!
Finally! I love undervolting - great thing!
For laptops yes especially cpus
For miners hell yah
For pcs i am better off searching r/overclocking for my card
Im doing it on pc:) its really good
I undervolted my 4070ti and reduced the power consumption by 20% with actually a 2% increase in performance. Main reason was because UK electric is too expensive so trying to save money somewhat.
yeah, do the same for cpu, and you have a very quiet pc without the need of an AIO :)
When i play Star Rail the temp reach 86c but after undervolt it lower the temp to like 65c
I bought my "MSI GTX 1080 Ti Gaming X 11G" on release back in August 2017.
Ran it stock for the first year then got myself into undervolting (never had undervolted before) and once I had tinkered enough and got very used to it.
I even undervolted the GPU my sister has too (she has my old MSI 1070)
Been running mine at 1848MHz on the core @ 900mv with 6106mhz on memory (+600mhz).
Pulling about 180-200 watts on average during full load.
In my case I dropped about 10 celsius on max load with these settings (sitting at rock bottom 60 celsius now instead of 70-71)
Also pushing the memory has been very favourable for the pascal series GPUs and I think that could easily minimize or wipe the slight performance loss for the undervolt entirely.
Love your videos!
When i still had a 1080Ti (Gigabyte Aorus Xtreme), I could run it 2000mhz @975mV with ~185-205W powerdraw compared to stock 2050Mhz boost it could gain at 250-280W powerdraw. Though i was also custom looped
DDR6 on RTX20 cards clocks up well and can bring the card to life. When I got my (current) 2060S I ran a basic OC to see what's what, I gave it about a 7% OC, but I was really confused because with the OC my synthetic scores went down. Then I played with the memory, I got the memory up by 1000MHz to 8000MHz and my synthetic scores rocketed up from top 46% to top 19% at that time with both sides done. I ran it unbroken for a week and it was totally stable, not a single crash. I mostly run stock now because I really don't need the extra performance at this time but it's nice to know I can get a bit more life out of this when it starts to creak then when it's on it's last legs UV it to buggery to drop it down to a lower tier performance and use it as an enhanced video adapter in another machine (or maybe in my main rig for some extra video out ports in a x4 port) for years to come.
@@darthwiizius Oh yeah when messing with the memory:
Just do back to back benchmarks and compare the scores and when you start seeing smaller jumps or the score goes down, revert it once to be safe.
A lot of people tends to push it till just before they see artifacts,
which will offer similar performance to something closer to stock and more strain.
@@MrBluePoochyena I see, I'm just praying that the memory doesn't fail sooner or later
since that's what mainly has been killing these older pascal cards.
@@mr_cryzler34 If i had ran the car aircooled, I wouldn't even have been able to reach even close to the 2000mhz clock with 975mV, as the good old more heat the card produces more voltage and power it consumes.
I always think of buying used gpu then undervolt it but afraid to do it. Now I understand that it doesn't really affect the gpus' performance that much. Thank you for this wonderful video!
The 1080 on undervolt comes at an astounding average of 70Ws at the mythical 847mV while only losing between 7-11% of the brute performance, I say it's very worth it if necessary (Tested on a 10100F rig so it can very much vary)
Edit: Grabbed a Moderately Priced 5600X myself since my previous rig commited delete Sys32 and the max power consumed from the UV 1080 was 115W in CyberPunk 2077
Wow!
850mv is crazy
@@vinylSummer It's a very well known frequency from back in the day (2017, back in the day, I cant believe I'm saying that) where the card retains great performance while also dropping a noticeable ammount of power. 2016 Nvidia moment
wtf, how that sillicon is considered normal?
@@saricubra2867 beats me but if it aint broke, dont fix it
Also if your GPU is quite enough to reach your refresh rate, don't hesitate to use VSync or framerate cap. It can reduce power consumption in less demanding scenes of game. Combine this with High graphics instead of Ultras and you get good visual fidelity with good economy😊
Undervolting went great for me... I messed with my 5700 XT Gaming X and upped the power limit by +30, a stock, non-undervolted card could consume upwards of 300 watts.... a slight undervolt from 1200mv to 1140 not only lowered power consumption by roughly 30 watts, but preserved the performance boost gained from raising the power limit and lowered the temps by ~10 degrees. These sorts of tweaks really make the 5700 XT undoubtedly one of a few, if not the best bang for the buck gpu you can get atm.
14:28 The graph's labels are switched. Other than that, this is a great video to show how undervolting can minimally affect performance for massive decrease in power draw. Great work.
Undervolting is amazing! I own a RX 580 (2048sp) and it used to consume around 150-180W in most games at default voltage and clocks (1150mV and 1284Mhz), but after a 150mV undervolt it managed to use only 100-140W and the temps were way better, going from 75c to around 60-65c, making less noise and less heat.
You own an RX 570*.
i have that gpu too
@@raresmacovei8382 its a 580 bro
@@blabahs 2048 cores is a 570, not a 580, regardless of the name on it.

And before you say anything: I know that it basically is a RX 570
Undervolting and power limiting are insanely awesome ways to get more power savings. I managed to drop by 3070 Ti from 290W to 220W while losing barely any performance in any game by overclocking the balls off it. It was awesome.
i undervolt then limit my tdp as far before lowering performance from stock. right now my 6900xt is running at 198w full load and it still performs 3% better than at stock @ 265w. (these are core TDPs, board power is higher, but i also lowered that significantly on my gpu, but i have no way to measure it that i bothered to... don't feel like measure at the socket)
I mostly use my 3060ti at 1410mhz and about 0.695V. It uses only 100-110w even in 3dmark which seems fairly power heavy while performing like a 2060. And sub 100w in games
It’s wild that the GPU scene is so bad that we’re having fun making GPU’s less powerful. Nice video, as always!
Personally I find it a necessity to undervolt for longevity and temps particularly with AMD GPUs. From the RX 570 to the RX 5700 XT to the RX 6800 XT, every time I let them run at stock, they get quite hotter quickly and draw a lot of power (even if the efficiency of AMD GPUs have become better over time sans the RX 7000 series). Doesn't help that as someone in a tropical country with no aircon, the GPUs I run can actually at times hit throttling temps even with some cooling.
With undervolting (usually at 1.080V or lower depending on silicon quality, varies between GPU ofc) and slightly reducing from max frequency, I draw less power which can slightly help with heat as well (not much here in my country but would likely benefit others with lower room temps), maintain more ideal game clock speeds for some more frametime stability, and barely notice a performance loss.
This isn't a good perspective. You can always make GPUs more efficient with an undervolt or adding a slight underclock also. This has always been true, regardless of the state of the market.
More wattage does not mean "more powerful". The whole point is that FPS is the same at lower wattage.
Try turning the memory speed up on the RTX2060, I do that if I need a few extra frames and the DDR6 can be pushed quite a bit. I ran my 2060S memory at 8000MHz for a week once and it worked fine.
Living in Texas, this summer has been brutal. Perhaps an undervolt can ever so slightly make the heat more bearable, and for losing negligible performance I'd say if you can undervolt there's no reason not to.
17:45 reasons for undervolting is: so that games like Lost ark or New world or whichever game it was, doesn't fry your GPU when on the main screen.
As a 40 series laptop user, I can confidently say that the 40 series can be undervolted without sacrificing any performance, at least judging from the Time Spy numbers. A typical stock 4080 laptop can do just shy of 19000 in Time Spy, but the main limitation of this performance is not its Core clock speed, but the VRAM bandwidth. By locking the clock speed to 2340Mhz at 0.85V and giving the memory a +1150Mhz overclock, I am able to get a score of 19355 in Time Spy, while the power consumption is reduced from the stock 175W to just over 130W.
In scenarios where I don't need all the performance that 4080 laptop will give me (i.e. in Apex Legends), I've set a profile in Afterburner to underclock the GPU Core to 1755Mhz at 0.7V while leaving the memory at stock clock speeds. With this setting, it got 15166 points in Time Spy while using just shy of 90W, and in Apex Legends it averaged out at roughly 85W, and I am happy to report that this setting yielded me great reduction in fan noise while keeping the game running at 2k max setting 180fps+.😆
Another great video! Great to see the improvements undervolting can do! Keep up the great work good sir!
I have a rx 6700xt with an undervolt and overclock 1080mv and 2600mhz went from 80c stock to 65c, and now in summer I underclocked it as well 2133 mhz 1060mv and it reaches 60c but its always on lowest fan speed, lost about 8 fps but the watts went from 180w on undervolt and overclock to 110w on undervolt underclock. Its a great card honestly
my sapphire 2 fans runs at 1075mv with 2700-2800mhz core and 2122 memory (could push more but meh) its a really great card
Thinking of doing this to my 6950xt that’s coming Tuesday.
@30p per Kw/h which is insane I’m going to be kneecapping my system hard.
60fps caps too 😢
imo the biggest upside of undervolting is being able to run your fans quieter while keeping the same temps aswell
I got my Rx 6700 down to 100-120W so now my fans run at 1000rpm at 65c
Great video! I had an RX 570 for 5 years and was able to undervolt it while also overclocking it and it was completely stable the entire time. Probably the best GPU experience I've ever had, I got it during a promo where it was $120 brand new with DMC5 and RE2 remake steam codes included. Those were two games I was already going to buy, so it was essentially a free upgrade. Crazy how the market has changed since then. The only reason I'm not still using it is that I wanted to give it to a friend as an upgrade.
Thanks!
I had a 2060 Super that I undervolted from 180w down to 140w with no performance loss. Then I upgraded to a 4090 and did the same thing. Down from 400w to 250w, albeit with a small performance loss (
Undervolting is great for the summer, when even the nights are hot, having a GPU pull 300W while playing makes the entire room a sauna.
My Powercolor RX 7900 XTX pulling 300w while undervolted: 😇
You can always save even more power if you're willing to drop clocks a bit also. Shave 100 MHz clocks of your GPU and you'll be able to undervolt even more.
For Radeon users it is best to use the power (TDP) limit in the driver software (for supported cards) as the card will automatically under volt and adjust clocks as necessary. The clock speed will depend upon the load. So for some instances clocks will not drop. There are real power savings as this metric sets the total power draw of the card which I have proven the reduction with my wall power monitor. (I own XFX RX 590). Some real advantages over under volting manually are: because the card is controlling the voltage and clocks it will not hang/crash or become unstable under load, another point is that the Radeon software allows you to set the power limit globally and per app.. (you can create profiles)so for games that are less demanding you can have more aggressive power limits for them and for games that require more processing power you can have more relaxed power limits (the card will run higher clocks and draw more power). In my experience with the RX 590 which is designed 200W TDP (196W) to be exact when I set the power limit to -50% the driver software reports consumption of around 96 to 99 Watts which is also in line with the numbers is see on the wall power monitor (a reduction of 90W+). Nothing is wrong with experimenting but radeon power limits will be easiest and best for most people to save some power and not sacrifice much performance depending on the card load.
I undervolted RX 6700XT at 2300mhz/1025mv. It only uses 100-120w (default:180-200w) with acceptable performance loss. Very useful for my SFF case
How much performance loss?
The other day I undervolted my daughter's GTX570 (you know...HOT fermi) because heating the room in the summer isn't a thing. Oddly enough, it worked. Managed to drop temps by 7 degrees and not lose any performance. Could also drop it more and lose just a few MHz. So it works on much older cards too.
Also, for years now my trusted RX480 at 1.005v doesn't lose any performance while consuming only 75-78w.
In addition to Vega, the R9 Fury series is another great candidate for undervolting. They don't overclock much at all. You will be doing good to get another +50 to +100 on the core, and MAYBE with the right drivers (16.12.2 was the last driver version to support Fury HBM overclocking) you can get +50 on the HBM (Fury HBM steps up one level from 500 -> 545, but it is VERY RARE to get them to step up to the next level at 600). HOWEVER... they can OFTEN run at stock speeds with anywhere from -50, -72 or -96mv, sometimes even with a mild overclock. This drops temperatures and power usage to GTX 980 levels.
Really wish the Radeon VII made an appearance here, being that it's the card that needs undervolting the most
For sure, Vega cards and 7900 XT/XTX cards need undervolting the most
I have a Vega56 I’ve undervolted /overclocked and it’s awesome. Undervolted and on normal clock speeds it does about 110 watts. But on its max performance config it does 225 watts.
Always coming through with banger videos buddy.
When I saw you dragging that voltage curve down the CORRECT way I just said "good lad", the amount of people that do it wrong drives me insane, esp bigger youtubers
I got an rx5700 running stable undervolted to 925mV. The core clocks are at 1860 and the memory is at 1850. Both of which are the max clocks on the radeon software. It consumes 130watts at most.
It was even mostly stable at 910mV but I mostly play Bethesda games so I just leave it at 925mV for some breathing room due to the instability of modded skyrim and fallout4 games. Lol
I tried swapping out the bios to get 150mhz more but it needed 100mV more to be stable and it increased the power draw by 40watts. It wasn't worth it for a 3% actual performance gain so I'm sticking to the undervolt instead.
The amazing thing is that the Rx5700 performs on par with the 1080ti and you could regularly get it for under 150$.
You can even get a Chinese refurb one shipped to any part of the world.
Yep, ordered a chinese resoldered rx5700 at 118$. Gonna get my hands on it within a few days. Upgrading from rx580.
@@tanmay5570 yeah! I started with a chinese rx580 2048sp (essentially an rx570) then upgraded to an rx590gme( a chinese rx580 lol) now this rx5700 is my latest card and it's probably gonna stay for a while.
Wow! For all of us extreme cheapskates, this is a must watch video. Especially if you have a warmer room or live in an area with expensive power.
What I find to be easier is to max an undervolt on one profile and use it for everything that ISN'T a GPU bound game. Then, create a power profile to amp the GPU up to high performance when it's needed. When you go to fire up a game, simply click your OC profile and then the check button and minimize it. Now you have the performance you need when you need it. When finished, click on the low power profile and then check mark and minimize and you are back to sipping power. I cut my PC power bill in half (Literally took $20 a month off of the operating cost of this one PC). Granted if I play games nonstop all day everyday, this makes zero sense as you'd be in high performance mode all the time but for the average gamer and user it works well. Best of both worlds.
I have an inno 3d 2060 super and it's best to say the cooling system aint the best on it. Easily reaches low 80c. Undervolted it to around 950-ish mv. Now it's hover around low to mid 70c :D
Nice topic Iceberg! There is a proverb my great-grandfather used to say ''Bean by bean you fill your bag''. Well today you could say watt by watt you might not fill your bank account but for sure you could invest those 29 pounds into something else.
Additionally undervolting, fps limiters, sufficient air flow, regular cleaning and maintains are some "inexpensive" ways to keep your computer parts cool and long lasting.
used amd 6000 series are a blessing from the heavens!
I bought a used 6800 xt for 260 dollars! and it works like new!
undervolted my 3060 from 170w to 100-120w, did that to keep my non airconditioned room temps undercontrol
Undervolting RDNA 3/2 and Ampere/Ada GPUs doesn't really affect performance much (and even improves clockspeeds and frames in some cases) but I vividly remember having terrible 1% lows and stutters when even using the smallest undervolt with older architectures 🤔
Wonder what happened?
I discovered undervolting when I upgraded to my Red Devil 6800xt this spring since it's an option built into the AMD software - Like you showed, at a certain threshold it becomes unstable in certain games, but once I found that limit and kept just above it, I actually GAINED some performance because it reduced temps a bit, allowing it to overclock closer to the target I'd set for it! Lower power consumption for better performance? 100% worth the bit of time invested.
There's two aspects you kinda overlooked: You used Cards with good/sufficient cooling solutions (and I assume in a open or well ventilated case) and sufficient PCIe power connectors, but a lot of cards struggle with those.
The RX 480 had some released with 1x 6-Pin (and then exceeded the specs for the PCIe slot to get power), some GTX 1060 had solid alu block heatsinks, the RX Vega was the posterchild for undervolting for temperatures and that's not even starting with all the blower style and/or OEM cards.
Thank you for changing the music this time.
My room gets hot during summer making gaming a dread and if you don’t have an A/C unit, undervolting helps with the amount of heat been exhausted into the room.
Keep in mind that, before RDNA 3, power is not 100% accurate measured. Sensor is only for asic power if I'm not mistaken. So that 580 is not drawing only 130w, 6700 is not drawing only 160w etc.
My brother owns a HP GTX 1060 with a weak cooler and it throttled to around 1600MHz in less than two minutes. Now it runs at 1689MHz at 800mV at around 75°C. I also overclocked the vram by 340MHz so it performs 5% better and only consumes 80-85w instead of 110-120w. :)
I have undervolted a 6900XT and resulted in max power draw of 220W, 80-120W down from stock. FPS is nearly unaffected, but it also reduced core and hotspot temps by 20C. Similar story UV on a 5800X3D. 🎉
That’s cool!
I’d like to see how it works on older GPUs, such as 780/ti, 980/ti, vega 56/64 etc
🔥
Me too
Just look up the similar Quadro or Firepro from the generation in question. They tend to run at a better compute/Watt ratio because companies look at that kind of thing. Not just for the power used, but to make sure that they will be able to cool the datacenters they put it in. In fact, get a Quadro because it might have a better bin of silicon.
Maxwell 1.0/2.0 and Kepler/Fermi, require vBIOS mods to be undervolted properly.
Maxwell not really. I bios mod them cause i dont wanna tinker with msi afterburner. In any case. Drop the power limit and overclock them. On one side you limit its power while overclocking maxwell what it actually does is shift the voltage power table so in reality you are using the same stock clocks but a using less voltage per clock thus letting gpu boost peak at higher frequencies. What i did find is you can also undervolt the memory controller vía bios mod thus saving some heat and watts that can go to the gpu itself.
Case in point i currently have on one of my systems a 980ti powerlimited at 180w and memory at 3200mhz (lower than stock). I would love to have a stock 980 to compare but i believe by benchmarks alone that its much more efficient. Like 10% fps to power ratio than a stock 980. Maxwell are crazy efficient for a 28nm design. If you keep them circa 1000mv mark they are awesome.
A couple of years ago i also did have two 970s in sli, overclocked and power limited at 135w each and and those things were fast, shy of stock 970 performance and much more usar friendly noise and power wise.
Regarding kepler... memory overclock can make a difference. Maxwell memory compression and newer algos did a lot of "magic" for efficiency and those are not present in kepler obviously. At least those where my findings using gtx 670 and gtx 760. God knows why the gtx 760 was able to pull like 1700mhz on those magic gddr5 memory chips.
Also on all GCN and terescale ark card (on the amd side of things) you must try altering memory timings, there is free performance there if you fine tune it.
Undervolting is hard locked on Kepler (780/Ti) and Maxwell (980/Ti).
You need at least GCN2 or Pascal (GTX1000) for software voltage tweak. Otherwise, your only option is a vBIOS mod.
I undervolt my 7900xtx from 1150mv to 1070mv over a 100watt difference and gained about 5-10% performance.
Doing this in laptops is particularly useful, you get less heat which ends up throttling less and makes you get a more stable experience, and you stress less the AC or the battery
This was a great informative video. Thanks for sharing. I may try this for fun.
I run my 6700 XT at 2600-2700MHz on core, +15% power target and -100mV undervolt. Works like a charm.
Im gonna give this a try with my 1660 super. Its in a restrictive case so the temp drops will be great. My electric bill will thank me too
My Gigabyte GTX 1660Ti was pulling on average 125W on full load at 1000mV, 1900mhz core clock, while also reaching temps arround 76°C, it was really noisy aswell.
Managed to undervolt it to 825mV, 1830mhz core clock, the temps went as low as 69°C, it still was a noisy mess so I had to set up a custom fan curve.
So far undervolting has been a god sent.
1:45 i appreciate the unexpected french on the screen :p
Most people skimp on psus, especially those that use cheap as chips used gpus. Undervolting will lower the risk of house burning down - another positive!
You undervolt your GPU because it uses too much power, I undervolt my GPU because it overheats. We are not the same.
nice having another tune in the background
The polaris undervolt is quite similar. My rx 470 can be undervolted about 0.1 V to 0.1375 V.
Daily drive a RX 6600 stable at 1030mv (and I think I lowered the core 50mhz). Games draw 60-90 watts.
I play older slow paced titles (think RE2 remake, RDR2, Snowrunner, SOTR) at 1440p upscaled to 4K at 60hz. Very happy how it looks, runs, and how little heat it puts out
if you own a Vega, always use HBCC in more demanding games. However your system ram needs to be really stable to do it, as if your overclock has any cracks in it; it will find it.
400/500 series that were used for gaming have discolored shrouds because of overheating. My GB 4G 580 didn't want to hit 1300 something boost clock because the VRM's were overheating. New set of thermal grizzly pads, MX4 paste and still. Undervolted to 1070mV while overclocked at 1400MHz Coreclock (don't remember VRAM OC). Card was rock solid at 1400MHz. In my opinion, those that mined have far less temperature cycles and stress on them. Would always prefer a miner one.
MSI Gaming X 6600XT heavily undervolted while overclocked to 2750MHz (2500 Memory). Powercolor Fighter 6800 undervolted to below 950mV while overclocked to 2490 (had some trouble staying within the undervolt that I like while hitting 2500, so settled at 2490) and 2250 memory clock.
All cards were ran under Linux at a locked coreclock in game. In my opinion, Linux doesn't like as high junction temperatures as Windows so coreclock starts to throttle at around 85C on the junction.
TL:DR you can overclock these cars while undervolting.
Definitely UV is a must. I have a 1660TI that can easily consume 156W@1980MHz on stock and run at 85C+. I undervolted it to 775mV@1850mhz with +1000MHz mem clock. Now it only consumes around 73-75W and 65C max with performance loss around 8% max
My GTX 1660 Ti is running at 825mV since I bought it last year. Powe consumption in heavy games is 85-90 W most of the time, from 125-130 W with stock settings. I slightly underclocked the the GPU core (100 MHz less), but overclocked the memory from 6000 MHz to 7500 MHz, so the performance is almost the same as stock. Temperature also dropped in 5-10ºC.
as a enthusiast i love your videos so much
Since i gained a quite nice boost on my rtx 3080 laptop by undervolting i am going to undervolt anything i get my hands on from now on. It´s essentially free performance, sometimes more, sometimes less depending on silicon lottery. Specially in powerlocked parts, the powerdraw stays the same but clockspeeds go up.
at the 11:00 minute mark i think you can do a better job with the graphics. you can increase the size of the blue bar to the size of the first red bar. this way we can clearly see that the red bar reduces more than the blue bar (in %)
you should test vega VII and 56 undervolted. These gpu phenomenal for delta watt reduction and fps gain
Undervolting tamed my VEGA 56 to a max of 176 watts power draw at 1480mhz for the core and 930mhz HBM2. Still using this card since I'm only gaming on 1080p. :)
I'm not really that concerned about power draw and electricity bill but it's still fascinating to know how these cards hold up. What I do care about and advocate as to why everyone should undervolt is at 17:49!
Finally an undervolting vid
Ive been playing on my PS2 more then my $1000+ PC
I run heavily undervolted at lower clocks in most games because I rarely need my GPU to be maxed out. In return I get a much cooler and more quiet card. Modern GPUs are basically overclocked at stock and much more efficient running a bit slower.
I would say undervolt in summer to decrease the heat and overclock in winter to save in heating...
I also have my 1080 Ti at 1875MHz coincidentally enough, albeit at just 900mV. Goes to show how results may vary based on silicon quality I guess. I also run +400 on the memory, which actually puts it slightly above stock performance when all's said and done.
It is absolutely worth it to undervolt, just for the temperatures alone. The 2060 in the video (with a bad heatsink) ran 10C cooler with the undervolt, without losing performance. I have a single fan 1660Ti running with -95mV. At the same noise levels it runs 12C cooler than stock, only losing ~1 percent in clock speed (not noticeable in games).
My GTX 1080 still delivers in todays games in 1080p! No sweat at all. Such a BEAST of a card! ❤️❤️

I remember having to undervolt my 1080ti when it was dying. The card did eventually die and I foolishly replaced it with a 3070ti, but the 1080ti lasted a year or two longer.
My undervolted and under clocked RX 580's would burn about 95 watts and run between 50-60 degrees Celsius while mining Ethereum during the last boom. At one point I was raking in hundreds of dollars per day and burning very little power. All good things come to an end. All of my 580's were repurposed as budget gaming cards and have made many entry level gamers happy.
Hey man, what are your temps in the 1080ti with that "Rajintech" GPU cooler after a run of Heaven benchmark with max fan rpm? I own a blower card it goes over 70c with everything maxed out. I've manage to keep temps at a max of 57c in a run of heaven benchmark with a old 140mm 3700RPM fan at max speed pointing at the patetic stock blower cooler but its stupid loud, still better than the stock blower fan. The 140mm fan is just loud, the stock blower fan is loud and whiney. But I'm looking into upgrading to the same cooler as you.
Well, bear in mind 1) I'm in a non-climate controlled room, 2) I don't know what my ambient temp is, and 3) I'm not using a case.
After about 10 minutes with the power limit at 120% and GPU clock at 1936MHz (boost only, no overclocking), the GPU is running at between 55 and 56 degrees. I don't know much about the Arctic 120mm fans that are installed, but HWInfo reports them as running at about 1500RPM and they are some of the quietest I've ever (not) heard.
"Running Cyberpunk on a Voodoo 2" this hits me hard. I remember upgrading from a 233MHz Pentium II to a 500MHz Pentium III and finally adding a Voodoo 3 insted of softwere rendering, i finally maneged to play Tomb Raider 2, 35ish fps, it was mind blowing...
I used to run my 1070 at 1000Mv, it could do 925Mv but one game of course didnt like it..then a second 1070 walked past my rig and power consumption of course is out the window and i run them cranked but with a locked 1025Mv, i still shaved roughly 30-40W off the cards so they run full tilt around a 1080Ti's PC but i get more performance..especially considering all the unsupported games ive played so far have utilised SLi and scaled very well, meaning ive been able to choose between 1080p 120-144 or crank everything to max, 16X SLI MSAA, SSAA. DSR etc fpr 4k 60, the more i load the cards, the more they wake up and give me solid 0.1% lows, in games that dont scale well, i still find the 0.1% lows remain absolutely solid so that is still an improvement, they peak in the high 50s due to my cooling setup but i then chose Doom 2016 and when i put it to 4k, almost scraping 60 until heavy action, both those GPUs were pegged the 4930K CPU woke up with them and the cards hit 68C, whatever that game did, it was stressing them harder than any GPU benchmarks i could throw at them!
some cooling reconfiguring for the things did bring them back into the low 60s but considering i've saved money in the winter last year avoiding paying for gas and putting the central heating on purely as the PC can warm the room up for me, i think im going to be quite cosy this winter! Its amazing what old hardware can do today when overclocked, the sabertooth X79 and CPU for 90, same for each 1070 and the 32GB QC memory for 35 means for under the price of a modern entry level card at a tickle over £300, i got a monumental upgrade from a 4570 and 1060 3GB, chuck in the extra i spent on cooling overtime and its still cheaper than a 4060..and i got a whole PC out of it..Still playing 1080p high framerates, SLi helping to mask those dips under the monitors refresh rate.
There are some games that of course show the platforms age, but it still puts up a good enough fight to keep on using it until i can afford an upgrade that will see through their limitations to make it worth it for me the longer i wait the cheaper hardware becomes and soon i'll have a 5800X3D and 3080, if threadripper wasn't dead i would use all of that memory bandwidth in a heartbeat and part of me will miss the gone era of QC memory platforms as i gained 35-42% gains from a temporary dual channel to quad channel configuration..and to think we don't see those improvements today from platform to platform..perhaps i may wait until QC makes its way back to consumer platforms..imagine an X3D Chip and QC support, perhaps it may be AMD's secret weapon if intel can step up in a big way..
TL'DR: Whatever GPU you have, ALWAYS undervolt. It's a silver bullet.
Over the past few years electricity has moved from a thing I top up when the alarm warning goes off when its low. To something I think about daily. Its changed the way I use a PC. My main tower PC is only on a few hours a day now and Ive shifted my gaming habits to suit a mini PC.
I'd recommend trying to undervolt the core while OCing the memory. It tends to give just enough performance back after lowering clocks slightly to keep performance about the same as stock. I got a 2060 down to 145 watts while having basically the same performance as stock due to the memory OC.
I have a 3070ti and right after I got it, I undervolted it and dropped from always above 280w to always below 200w. I did drop the clocks from 1950mhz to 1800mhz but voltage from 1050mv to 900mv. Anyways, I didn't need all that performance as I only use it at 1080p. I didn't do it for a lower electricity bill, just for lower temps(about 80C all the time with 45% fan speed to 67C max with 31% fan speed). Very noticeable drop in loudness(almost as loud as a room fan at low speed to incredibly quiet that I have to put my ear right next to the case to hear it). Mine is the palit 3070ti version. I don't exactly know the name
As an alternative to undervolting, what about lowering the PPT?
why is it that the 6700 desktop variant is so inefficient? The laptop version (6700m) which I have does about 2400mhz at like 110w and beyond that it gets too hot mind you, but if I just run it for the first 10 seconds or so it can do 2500mhz at around 118w power and just in seconds its throttling haha
my best is about 90w power and 2100mhz frequency, undervolted and overclocked using MorePowerTool
Undervolting rocks - it's been super helpful to me given that my room gets to 33-35C ambient during hot months (and no, air conditioning isn't an option). I currently use 1680mhz core and +500 memory @ 775mV on my 2060 when playing demanding titles - this cuts power to about 115w max. I've tested 1470mhz and -500 memory at 700mV recently - this cuts my power consumption to ~85w. I'll be using the 700mv profile in situations where performance isn't essential.
Your videos are so high quality for such a low sub channel bro
Thanks! Though tbh I'm kinda shocked so many people have subscribed...
@@IcebergTech U make very very high quality videos why would people not sub?
My RTX 3060ti is running at 0.756mV with clock of 1600MHz. Yes, you lose a bit of performance but it's incredible to see 90-115W (on full load) of power consumption on such powerful little card. I like to cap fps to not generate extra stress. I can comftably play RDR2 at 1080p mostly Ultra (with fsr Q) with super stable 60fps with gpu power usage of 50-85W.
Also made a bit different preset. exactly 1mV with clock of 2000MHz. It's still a bit lower voltage from original while achieving higher performance. It took around 190W.
You made me want to search for even lower power consumption on this little beast
I have no problems with electricity cost where i live, but i always undervolt my videocards for better thermals and less noise. Which is especially important for postmining cheap RDNAs (got my rx 5700 xt Asrock Challenger in April for about 150 USD)
I am running my RX 6700 undervolted and underclocked to 1090mV and 2400 MHz max, but overclocked memory to 2150MHz. Result is excellent temps, pretty stable(can crash sometimes on more demanding games, but can be upped a bit if needed for such games) and performance is the same as on stock settings. Power consumption is 120-130W (my goal is 1440p 120fps)
14:37 "RDNA3 is reputably far more efficient that previous generations"
That couldn't be farther from the truth lmao. At best they match efficiency and at worst AMD dropped the ball and made RDNA3 LESS efficient.
Good job Radeon group. Dissapointing as always
It's nice to live in a place where power is dirt cheap because of all of the Hyrdo-electric dams, my power bill is very low compared to most places
I just start doing undervolt to rtx 3060 last night i could say its very good the power draw really drop like 40 and the temps tho
Undervolting both GPU and CPU is the best free improvement you can have. This is the way!
You should have tried dropping clocks on the 6700, it does wonders for the voltage offset on my card.
2:55 that's RivaTuner which comes shipped with Afterburner? It can be run standalone, too. At least that was my impression; please correct me if I'm wrong.
Anyways, great video! Thanks for the inspiration; gonna undervolt my 2060 just a tad now…
I remembering doing this on CPUs on laptops back in 2018, until Intel removed this feature because it involved using SGX and there was a vulnerability discovered that required it to be locked to solve it
Yeah, my Razer Blade would be a dream if I could undervolt the CPU. Unfortunately it can't, so I'm stuck with fans spinning even in light use...
