Define what sorts of quirks are we talking about when in idle? Just recently undervolted my i3 in a ITX build using offset cpu voltage so it still can scale itself down to 0.625v when in idle while not using the original stock voltage in under full load.
undervolting has similar characteristics to overclocking. when you undervolt too much, it will be unstable, same goes to overclocking too much, it too wil become unstable. I undervolt my R5 1400 from its stock 1.25V to 1.14V and overclocked to 3.6GHz which result in better performance and less power usage.

Dude, I have an HP Envy with an i7 4720hq. While rendering one of my own blender scenes with turbo boosting turned off(cpu running 2.6Ghz), I will reach 82-84c with a zero offset voltage of 0.885v. I offset the voltage by 0.1v down to 0.785v and the temp dropped to 69-71c, that's a 13c drop. Absolutely fantastic. I tried a 0.12 offset and it crashed..... I was hoping to squeeze a little more out of it but I cannot complain at all about a 13c temp drop. Thank you for this video.
@@fortuna19 On laptops especially its a pain. Temp difference can quite high. If you got a golden chip undervolting could even reduce temp by 20 degrees in some (rare) cases.
I was able to overclock my i7-7700k to 4.7GHz @ 1.12V. It was rock-solid stable, and silent! This is on a Asus Maximus IX Hero (Z270). I have since OC'd to 5GHz @ 1.25V , just because I NEED that 5,000,000,000 Hz... lol
5GHz + 1.25V + 100% AVX CPU usage + 100% fan & pump speed on Corsair H100i V2 = 85C max I would love to delid and not need such high fan speeds. I really shouldn't have cheaped-out on the cooler.
man that thing is a beast for overclocking as IBT maximum takes a good bump in vcore for me to get a passing score i can run it without blue screening pretty easy but for it to pass a 10 run sweep at the max ram i can give it it ussaly need a good +40mv tp 50mv over what i can pass on rog real bench. quite an impressive chip you got there to handle 5ghz under avx on ibt as most need an offset for that
Dude thank you so much! I watched this video before and just recently built a system that used this perfectly. I have a 2600x that was ramping the fan up like crazy and spiking temps along with fan RPMs. When I pulled up HWInfo I noticed that the vcore was ramping up to 1.45v!!! I set the vcore to 1.2 with an all core clock of 4.0ghz and it was whisper quiet! I'll adjust clocks up to turbo and see what vcore is required. Made an INSANELY loud system run smooth as butter with much lower temps
undervolting is the holy grail for laptops, especially compact ones. i have an alienware 17 r3 with 6700hq, it ran at 1.2v stock, i managed to drop 135mv fully stable with it and i got much quieter fans AND 10c off my load temps across all cores. Best thing about this is essentially risk free, and very very easy to do with throttlestop or xtu
@@seanlacroix may I ask what application you used? I got a predator 15 and tried the msi program based off the recommendation oglf the internet and it doesn't even let me adjust the voltage of anything, not even the fans
My personal Intel Celeron laptop is fully Locked and I can't undervolt it at all, even on Intel XTU. 😭😭😭😭 But Wait!!! One day, I was going to Mom's office because there are no one else at home, and then I suddenly found an empty unused PC there at the Office! Unfortunately it had a spec of a potato, with a Pentium G3620 (Dual-core 3.3 Ghz) & 2 Gigs of DDR3... But the fun thing is that I could install Intel XTU with no troubles at all! I tried to undervolt it to the limit, as most kind of people do, and I started from -55mV and keep moving down every 10mV to -65, -75,... I was suprised that I could put it down to -150mV!! Moreover, the Maximum voltage at stress test is now only at 0.947 volts, which is pretty low on a desktop CPU... I finally stopped at -195mV @ 0.895V since it crashed after 30 seconds of stress test. So I turned it back up to -135mV. But -195mV is a really massive number on the CPU world, and moreover, this is desktop CPU!!! Note: using Intel cooler
I love undervolting! In my office were running Ryzen and Epyc platforms and undervolting has overall made our office cooler, quieter and much much more pleasurable. For most of our work 3.4ghz is plenty and if it isn't we can offshoot it to the server. We were able to drop the voltage to 1.1v on a few lottery winners and 1.18v-1.24v on some others. Cool temps! With some systems with Noctua NH-D15s, full load temps could be well below 60° at full load for 10-20minutes at a time. This is better than overclocking!
This is great! As a laptop user this is extremely helpful. Running on a Intel i-7 9850h clocked at 4ghz by laptop manufacturer. Managed to undervolt 125 mV stabily and now I no longer have heating issues, thanks.
You can also undervolt and overclock your cpu at the same time, to balance temps from the overclock. My 3770 (yeah, non-K) at stock of 3.9ghz and 1.365v would idle at 27c and cap at 67c at full load. I've been running it at 4.60ghz and 1.185v for years now, never seen it go any higher than 65c at full load. Since day one, I'm using the stock heatsink but swapped out the crappy 1600rpm stock fan with a NIDEC 80mm fan that rolls at 7800rpm tops (never goes over 3000rpm though). You can also lower CPU PLL from 1.80v to something like 1.60v, and that too will lower your cpu temps.
Lovely video. =) This is especially relevant now with AMDs processors out there. AMDs old Piledrivers loved both undervolting and underclocking and you'd get a significant improvement in performance pr watt in both cases. I don't know exactly how well Ryzen tends to respond to undervolting, but I know that if you *also* under-clock them you'll get significant efficiency gains.
ryzen undervolts well for my 3600x undervolted and base clock adjusted (wont ramp up in clocks) that was to agressive on amd original settings, i dont know if the voltage or the clocks set to high original, but since i've put my own clockspeed @ 4.2 ghz and lowered the voltage (srry don't know the numbers anymore) its stable since no bluescreens anymore..
So undervolting can be used to run your system cooler at normal clock speeds or even slightly overclock without increased heat in some cases... good to know. It's real nice that this guy cam discuss with enthusiasm more than one type 9f optimization.
I undervolted my i3 4150 and intel HD 4400 , after a lot of cpu stress test and gpu benchmark I found the right voltage offset , now my cpu runs at 56 degrees at 100% stress load , before it was hitting 72 degrees on stress test . CPU and cache voltage offset :-134.6 mv iGPU : -105.5 mv
I just got a used i9-11900k for 120$ installed on my Asus B560M-A HTPC rig, turbo boost disabled, vcore set to static at 0.905V, (all cores synced at 3.5GHz) Coolmaster g100m low profile air cooler, running very stable with more than 50% performance boost compared to my older i5-11400 CPU. I can now go withnextreame settings in MadVR w/o any frame drops as with the i5-11400 (I have 16GB DDR4 RAM xmp-1 profile). Best 120$ ever spent.
I undervolted my surface pro 3 and my SFF PC and get a great reduction in heat and noise. the SP3 was mainly for heat while my desktop was for noise reduction. great video!
I underclocked my 8350 for fun one day. cant remember the voltage but it was much lower than stock @3.5, with only 2 cores running. I did this for certain games that dont require a monstrous cpu. It ran great, low temp, no noise (with evo 212). I only used this underclock for a few days so i forgot about it and played GTA V. Loading was incredibly slow but once in game there was barely a noticeable difference. "why is it laggy tod... o yeah. only 2 cores."
Why didn't you mention the power saving? Good for your walled and especially great for a laptop. You might get a significant longer running time if your laptop bios supports to change the voltage.
Hi! I am the guy requesting help with a Silent build under the last video. This video really helped me figure out some stuff before making my purchase. Just wanted to thank you for the immense effort you obviously invest in your video! I really think you will blow up and become really big if you keep at it with the same effort!
I undervolted my Alienware 13 R3 i7-7700HQ by -140 mv (stayed stable throughout all stress tests). It used to reach temps of 94 degrees Celsius during heaving gaming. Now it maxes out at 80 degrees! It was like buying a new laptop. Another thing is that the GPU temps are now much lower too. I think it might have the same heatpipe as the CPU or something like that. It used to reach 87 degrees.. now it maxes out at 80. Idle temps also dropped from 54 to 42. My battery life was also increased by around 45 mins. If you haven't done this yet, go do it now..
Undervolting is even more crucial in laptops where the size of the heatsinks and fans is very limited. Therefore if the CPU runs cooler the clock speed can get even higher (closer to the stock speed) since the system do not over heat at all even under heavy load like 4K rendering. Also your CPU drains less power and therefore your you can squeeze a bit more operating time from your battery.
A very good and very sensible video, I understand gamers in the pursuit of maximum performance but there are a vast number of tasks where continuity and reliability matter. I regularly process video with ffmpeg that uses all cores and threads and you want stability and reliability over peak performance.
I’m not even joking I won the silicon lottery got my Ryzen 5 2600 from 1.13v at 3400mhz base clock to 0.95v did multiple stress test like Aida64, blender renders, unigen heaven 100% stable. I also undervolted my gpu from which has been factory oc rx 5500xt btw from 1145mv down to 1045mv
I use amd overdrive for my amd A10-5750m processor base clock at 2.5ghz with 0.88v 2.8ghz with 0.925v 3.2ghz with 1.050v and 3.5 with 1.187v. Temps and ghz before around 90C and throtheling at 1.49ghz. Under load. Temps and ghz now around 75C and turbo at 3 up to the full 3.5ghz! From zero to Hero!
I have a pavilion gaming and it was going 95, 97 and even 99c sometimes. After undervoting I am now sitting around 77 to at most 83c for even the most demanding titles. Edit: that's the cpu not gpu. Cpu seems to overheat much more than gpu in my experience at least.
Thanks for the good video and explanations mate :) I wanted to know if undervolting has an influence on the performance or something. Now I got the answer: No. As long as I don't change the clockspeed/multiplier and just change the voltage of the cpu/vcor downwards, the performance will stay the same.
on a desktop if definitely wont hurt, but with a laptop all it does is help! you get cooler temps, quieter fans, AND better battery life. i added over an hour to my laptop with 150mv undervolt
this is a very nice tip... undervolting CPU will allow for less power draw, noise and temp. Too bad Intel locks their CPUs so i3 mini itx rigs (which would be great candidates for undervolt in mini-itx rigs) are out of the question. I do not know how well would it work on AMD Ryzen 3s, and i have my doubt about if there's a need to turn off any turbo technology on the CPU in order to gain stability when undervolting (that will hurt performance). But since most CPUs have a safety overvolt in order to work with any shitty PSU, i think there is a chance of reducing voltage (at least a little) on any CPU if rig allows. And that's not only for new tech rigs, AM3+ FM2 and any older LGA from both intel and amd can be undervolted at least a little
I have a i7 6700 and it runs with core voltage in 0.990V. I did undervolting and I recommend. I never saw my chip overcome 49 degrees, even at 100% for hours!
i got ban from live stream chat, he asked how to reduce heat, so I recommended undervolting, and his fans say don't it's gonna fry the CPU, then he was like "YA BRO I AINT DOING IT TROLL" I'm just speechless
Ok 1 question, if we can lower the voltage of the CPU and get the same performance(clockspeed) and low temp, then why are the intel's CPU did'nt set its own voltage at that level for more efficiency?
Because not every CPU will behave similarly with under volt or over volt. The default voltage rating is the value which they promise their CPU to work with deterministic result.
I have nvidia rtx 2060 and i just went down from 1.1375V to 0.95V. Temp on stress tests dropped from ~48C all the way down to ~37C. Maintained stability. Thanks for the advice ;)
Nice video and interesting data. Almost seems like engineers have taken a lazy safety margin above the bottom instability point and are operating in a higher wear area maybe even.
You can TOTALLY undervolt your locked Intel CPUs. I built a SFF PC for my bro about a year ago with an i5 4460 in a GA-B85N- Phoenix motherboard, and the Arctic Freezer 11 LP I bought for it was a bit too loud, so I undervolted the CPU in the UEFI. I was very easy. 100% recommended.
So smart!!i didn’t know it could happen never tried it before I am always driving my cpus over the stock voltage just because I can and I don’t really care if the chip dies..but for home theater setups or just a daily office pc that would be nice because you can save on repairs (maybe)!!
Update - just got a Coffee Lake that the board says needs 1.205 V at 4 GHz... runs fine at 1.01 V. So low I can't use offset voltage because the idle would be less than 0.5 V :P.
Yes it does I just got into pc gaming with ryzen 7 4800h and rtx 2060, in winter when we have like under 30c and as low as 19-24c at best, it was pretty good being able to keep its clocks nice and high, but now it's summer with 35c+ to 40-42c temps and lowest 33c, it was struggling and so I disabled the turbo (did not want to install ryzen controller) since I only play very GPU intensive games or games like valorant which give 144+ fps while cpu throttling anyways, it's pretty good under 85c most of the time. While boosting it almost immediately reaches 95c, but you gotta give it to those ryzen chips man, at idle it's literally averaging 45c it's crazy like just 8c over the ambient.
@@Varad13Plays 85°C - 100°C range is pretty damn toasty for those Ryzen chips my dude 😬 they will definitely start thermal throttling with that range under load. Try everything ya can to get it cooler!
@@TheNightKing22 chips are rated to not throttle till 105c man and asus has done a bad job with its cooling, I am going to cut vents into the bottom panel and add some copper heatsinks on, replace the thermal paste then it should be better
@@Varad13Plays well you're right the actual limit for the 4800h is 105° but it does depend on which chips we're talking about where they actually start limiting. Still! CPU and GPU dies are not super stoked to be running close to those Temps, and in theory could shorten lifespan of course. Are you running an air cooler?
I bought an i5-6600K and the Z170 Platform in the thought that I'd like to get into overclocking. Have played around with it briefly once but haven't had anything consistent simply because it being stock was more than enough than what I needed it for, especially in games. I'll probably start overclocking when the 6600K starts to bottleneck other components which hopefully won't be for a fair while.
3:30 that's not 10%, it's actually 17% the ambient temperature is 21c, so the delta from ambient was just 30 degrees. you're not trying to cool ice here to sub-zero temperatures here. besides, if you're going for absolute values, temperatures start at -273.15 C, not zero.
Actually, I believe that undervolting CPUs and GPUs, while remaining stable, could possibly increase perfomance, as your getting lower temps, which means clockboosts will be more agressive :D
So you are new to overclocking cpu if you said that. You can have 1.52 volts max on 7700k (www.intel.com/content/www/us/en/processors/core/7th-gen-core-family-desktop-s-processor-lines-datasheet-vol-1.html). If you don't want to read it all you have a table at page 114, at 116 is for intel graphic chip. I am currently 1.375V on 5GHz after delid. Temps are now 70C max in prime95. I can hit 5.1GHz after delid, but i must put 1.48V to get it stable (prime95 86C max), so its a poorer chip, some can get 5.2ghz at 1.44V. So i have backed up because its a slow boost 100mhz for that much more voltage. 1.52V is apsolute max for 7700k, so its not safe (its like living on edge), but everything belove 1.5V is ok if you can keep temps belove 85C. Above 90C 24/7 will degrade your intel 7th generation cpu, but very slowely 2-3years maybe more, it depends on certain cpu, every cpu is different, and depends what are you using your cpu for. I had fx8370e at 4.8ghz at 1.5V 24/7 (max temp 55C) for year and half, no degrade, every bench test was equal all the time, now my dad is using it, everything works as it should be. Btw you must have a great motherboard so the power delivery and vrms can keep up. Only poor motherboard, or faulty motherboard can degrade your cpu at voltages lower then 1.4V, if the temps are at normal lvl. I will contact you in couple of months if everything is fine with my cpu, so that people know for sure. ;)
I actually did something like this with my R5 1600 since I got it. 3.2-3.6(turbo) speed, 1.118-1.4V vcore, which is waaay too much for the turbo mode. So I just manually set the whole thing to 3.6 ghz on all core and fixed the vcore at 1.2V - speed is way better, temps are somewhat cooler, and the most notable part: I measured 82W total system consumption while watching a 1080p60fps youtube video on default, and by fixing the vcore it dropped to 71W. Pretty neat.
3:35 did he just say 10% decrease? 10% decrease in degrees Celsius? Not the most scientific observation considering a difference in Kelvin is more meaningful measure of temperature
You have a very good CPU. Running Heaven benchmark my CPU drew as much as 1.368 volts at stock speed [not overclocked] and it fails to finish POST at 1.2 volts. [Edit] I forgot to mention maximum core temperature was 54 degrees C.
How does undervolting play out with Ohms law? If the voltage (U) is reduced and the resistance (R) reasonably is the same because you're not actually replacing resistors or anything physical within the laptop, the Amperage I would reasonably give a lower amperage as U=R*I can be balanced so that I=U/R meaning that a lower voltage results in a lower amperage. Is it simply that undervolting is adjusting very small amounts (in the 50-100mV range) means there aren't and substantial differences in amperage or is it something else i'm missing?
I've done this, i have a 7700k and a MSI Z270, I was putting in auto mode running in stock Ghz, that turns to 1.288 on Vcore... my cpu was getting 80-85 Cº on full load... So now i set the vcore on 1.118 and Load Line Calibration on level 3 (that's push to 1.160) and my cpu now only reachs 65cº its a huge difference... and also its not delided
My 7600 survived the Prime95 with a 150 mV undervolting. However, it crashes occasionally at idle. Thus I only got a stable 100 mV undervolting. I think this is the drawback of an "offset" undervolting. 1.2 to 1.05 is fine. 1.0 to 0.85 results in crashes.
My 2014 Macbook Pro laptop I have to undervolt and run custom fan profile to avoid constant overheating when playing computer games on it... With under volting it can run full 3,4Ghz boost 100% of the time with all 4 CPU cores at full load :) Without the under volting it overheats and throttles CPU speed down badly just from running GTA V at 40% CPU load usung GTX 980ti external graphics card...
Managed to offset my cpu core & cache by -75mV. Doesn't really help much on intense workloads as it still hovers more than 80°C even when turbo boost is disabled on my core i5 7200U @ 2.7-3.1GHz. Must be the slow and weak single 3000RPM fan on my laptop.
Here I7 3770 overclocked and undervolted, offset - 0.015 @4.1 ghz all cores, at stock speed should reach lower voltage than -0.015, but I do not want to do stability testing again
3:24 I think you mean -1.5% in temperature. Celsius is not an absolute scale, it's nonsense to talk percentage in C. For example, if it had gone from 0 celsius to 1celsius, you wouldn't say "+infinity percent" ^^
he actually means -17% because the lowest temperature an air cooler could possibly achieve is ambient temp. the temperature of the cpu is the difference from the end temperature from the ambient temperature. 51c-21c = 30c 5.1 is 17% of that.
Yes, but while 12 is 20% higher than 10, saying 12°C is 20% hotter than 10°C would be completely inappropriate and misleading (take the example of 0°C and 1°C if you're not convinced). But GraveUypo brought a good light on the matter I think.
This is Electronics 101 + or - 10% on all values. Voltage, resistance, capacitance, etc. Though with digital and precision circuits a well regulated voltage with minimal deviation from the recommended spec is obviously most ideal.
AMD Phenom II 965 BE C3 stock 3.4ghz 1.376v daily use undervolted 1.264v and 3.7ghz oc 44c full load temp or i can undervolt to 1.312 and 3.9ghz 51c full load temp. it's a thing for me from 2010. Only Ubisoft(Denuvo) with Far Cry 5 and AC Origin force my hand to upgrade my golden chip to newer gen because lack of SSE4.2 instruction set otherwise i can play all released games and enjoy not just play to date with 8gb ram and a gtx 970 at 1080p at high settings or above some at ~40fps some above 60fps but usually i use adaptive vsync to get rid of screen tearing so 60fps with neat details its more than enough for my ancient tech.

A couple minutes ago i tried on bf4 i got 140fps :/ idk what shoud i do , so my cpu temperature with stock mV between from 75-80 while playing game thats why undervolting my cpu
hozan tube you should try to repaste it with a better thermal paste and yes try reducing that undervolt. Even 200 is a bit high but start there and go down until stability is reached
i have dell g5 with i7 and i've made the undervolting, Thermal throttling has gone, but tdp drops down from 45W to 15W periodicaly espesially when the CPU and GPU work together, do you know why is this happening and how to fix that?
Anyone fancy spending a moment of their time to help me, i have a 7700k on a strix z270 and I've tried to get the best of both worlds, I've set a 4.7 clock speed hoping to be able to set a minor underclock, as it still runs stable at stock voltage (1.216V) on my board. I've set an offset of -0.01, is this the most i could expect?
I did this with my Haswell laptop 2 years ago, when I disable the undervolt the cpu will start overheating and thermal throtteling. I have -80mv and it helps so much.
you should always have the lowest possible voltage for you desired cpu speed, so the answer is always yes. for noise consideration you can run a 6700k at 1.28 volt with a noctua d15 cooler at 800rpm with no cores going over 70c. so i think any of the 2 latest cpus from intel can be cooled quietly with an overclock.

Define what sorts of quirks are we talking about when in idle? Just recently undervolted my i3 in a ITX build using offset cpu voltage so it still can scale itself down to 0.625v when in idle while not using the original stock voltage in under full load.
Instability. Loss off Data. Not rendering results as espectet.
undervolting has similar characteristics to overclocking. when you undervolt too much, it will be unstable, same goes to overclocking too much, it too wil become unstable.
I undervolt my R5 1400 from its stock 1.25V to 1.14V and overclocked to 3.6GHz which result in better performance and less power usage.
Quirks such as?
so erm basically you are saying in a long and windy way.... you have no proof that undervolting is the issue.

Dude, I have an HP Envy with an i7 4720hq. While rendering one of my own blender scenes with turbo boosting turned off(cpu running 2.6Ghz), I will reach 82-84c with a zero offset voltage of 0.885v. I offset the voltage by 0.1v down to 0.785v and the temp dropped to 69-71c, that's a 13c drop. Absolutely fantastic. I tried a 0.12 offset and it crashed..... I was hoping to squeeze a little more out of it but I cannot complain at all about a 13c temp drop.

Aida 64 , BOINC, ibt, with integrated GPU running fur Mark at 1400MHz
man that thing is a beast for overclocking as IBT maximum takes a good bump in vcore for me to get a passing score i can run it without blue screening pretty easy but for it to pass a 10 run sweep at the max ram i can give it it ussaly need a good +40mv tp 50mv over what i can pass on rog real bench. quite an impressive chip you got there to handle 5ghz under avx on ibt as most need an offset for that
I never realized you could achieve such a noticeable benefit when undervolting. I'm definitely going to mess around with this later in the week.
Agreed, Laptops really need it. Makes a big diff. Great video BTW !
Dude thank you so much! I watched this video before and just recently built a system that used this perfectly. I have a 2600x that was ramping the fan up like crazy and spiking temps along with fan RPMs. When I pulled up HWInfo I noticed that the vcore was ramping up to 1.45v!!! I set the vcore to 1.2 with an all core clock of 4.0ghz and it was whisper quiet! I'll adjust clocks up to turbo and see what vcore is required. Made an INSANELY loud system run smooth as butter with much lower temps
undervolting is the holy grail for laptops, especially compact ones.
i have an alienware 17 r3 with 6700hq, it ran at 1.2v stock, i managed to drop 135mv fully stable with it and i got much quieter fans AND 10c off my load temps across all cores.
Best thing about this is essentially risk free, and very very easy to do with throttlestop or xtu
I dropped my my 6700hq by 150mv and knocked almost 10 degrees off my temps.
Can i undervolt the CPU if i have overclocked the GPU?
Yep, and if the GPU shares anyway heatpipes with the cpu it will help the GPU stay cooler at higher clocks.
@@seanlacroix Nice!
@@seanlacroix may I ask what application you used? I got a predator 15 and tried the msi program based off the recommendation oglf the internet and it doesn't even let me adjust the voltage of anything, not even the fans
My personal Intel Celeron laptop is fully Locked and I can't undervolt it at all, even on Intel XTU. 😭😭😭😭
But Wait!!! One day, I was going to Mom's office because there are no one else at home, and then I suddenly found an empty unused PC there at the Office!
Unfortunately it had a spec of a potato, with a Pentium G3620 (Dual-core 3.3 Ghz) & 2 Gigs of DDR3...
But the fun thing is that I could install Intel XTU with no troubles at all!
I tried to undervolt it to the limit, as most kind of people do, and I started from -55mV and keep moving down every 10mV to -65, -75,...
I was suprised that I could put it down to -150mV!! Moreover, the Maximum voltage at stress test is now only at 0.947 volts, which is pretty low on a desktop CPU...
I finally stopped at -195mV @ 0.895V since it crashed after 30 seconds of stress test. So I turned it back up to -135mV.
But -195mV is a really massive number on the CPU world, and moreover, this is desktop CPU!!!
Note: using Intel cooler
I love undervolting! In my office were running Ryzen and Epyc platforms and undervolting has overall made our office cooler, quieter and much much more pleasurable. For most of our work 3.4ghz is plenty and if it isn't we can offshoot it to the server. We were able to drop the voltage to 1.1v on a few lottery winners and 1.18v-1.24v on some others. Cool temps! With some systems with Noctua NH-D15s, full load temps could be well below 60° at full load for 10-20minutes at a time. This is better than overclocking!
This is great! As a laptop user this is extremely helpful. Running on a Intel i-7 9850h clocked at 4ghz by laptop manufacturer. Managed to undervolt 125 mV stabily and now I no longer have heating issues, thanks.
You can also undervolt and overclock your cpu at the same time, to balance temps from the overclock. My 3770 (yeah, non-K) at stock of 3.9ghz and 1.365v would idle at 27c and cap at 67c at full load. I've been running it at 4.60ghz and 1.185v for years now, never seen it go any higher than 65c at full load. Since day one, I'm using the stock heatsink but swapped out the crappy 1600rpm stock fan with a NIDEC 80mm fan that rolls at 7800rpm tops (never goes over 3000rpm though). You can also lower CPU PLL from 1.80v to something like 1.60v, and that too will lower your cpu temps.
Content is spot on and the production quality is top notch. No corny jokes or stupid sponsored ads...:D
this is the most useful in laptops
Lovely video. =)
This is especially relevant now with AMDs processors out there.
AMDs old Piledrivers loved both undervolting and underclocking and you'd get a significant improvement in performance pr watt in both cases.
I don't know exactly how well Ryzen tends to respond to undervolting, but I know that if you *also* under-clock them you'll get significant efficiency gains.
ryzen undervolts well for my 3600x undervolted and base clock adjusted (wont ramp up in clocks) that was to agressive on amd original settings, i dont know if the voltage or the clocks set to high original, but since i've put my own clockspeed @ 4.2 ghz and lowered the voltage (srry don't know the numbers anymore) its stable since no bluescreens anymore..
So undervolting can be used to run your system cooler at normal clock speeds or even slightly overclock without increased heat in some cases... good to know. It's real nice that this guy cam discuss with enthusiasm more than one type 9f optimization.
Awesome quality. I see you are on your way to 10k. All you need is a few months...
300k
I undervolted my i3 4150 and intel HD 4400 , after a lot of cpu stress test and gpu benchmark I found the right voltage offset , now my cpu runs at 56 degrees at 100% stress load , before it was hitting 72 degrees on stress test .
CPU and cache voltage offset :-134.6 mv
iGPU : -105.5 mv
Now runs amazing same performance but at different temperatures, I forgot to mention that my iGPU was overclocked
I just got a used i9-11900k for 120$ installed on my Asus B560M-A HTPC rig, turbo boost disabled, vcore set to static at 0.905V, (all cores synced at 3.5GHz) Coolmaster g100m low profile air cooler, running very stable with more than 50% performance boost compared to my older i5-11400 CPU. I can now go withnextreame settings in MadVR w/o any frame drops as with the i5-11400 (I have 16GB DDR4 RAM xmp-1 profile). Best 120$ ever spent.
What happens if you up power, as there is some power throttling for me? I was able to underwolt 1.75mv on my i7 8750h
I have same processor, how did u undervolt?
I undervolted my surface pro 3 and my SFF PC and get a great reduction in heat and noise. the SP3 was mainly for heat while my desktop was for noise reduction. great video!
Damn, that's a great idea for the Surface. Thanks for watching!
I also have i7 7700k , undervolting it to 1.10v works, should i leave everything [auto] other than 4.5ghz/1.10v ???
All Aperture Science personality constructs are designed to run in apocalyptic, low-power environments of as little as 1.1 Volts.
Val i have an i5-7600k overclocked to 4.2 ghz at 1.095v
Damn, your videos have come a longggg way. Well done mate, keep up the fantastic work!
I underclocked my 8350 for fun one day. cant remember the voltage but it was much lower than stock @3.5, with only 2 cores running.
I did this for certain games that dont require a monstrous cpu. It ran great, low temp, no noise (with evo 212).
I only used this underclock for a few days so i forgot about it and played GTA V. Loading was incredibly slow but once in game there was barely a noticeable difference.
"why is it laggy tod... o yeah. only 2 cores."
Why didn't you mention the power saving? Good for your walled and especially great for a laptop. You might get a significant longer running time if your laptop bios supports to change the voltage.
it doesn't need any special bios since 4-th gen, all laptops with core i series CPUs support undervolting via software like Intel XTU or Throttlestop
3:26 That's not how temperatures and percentages work. Don't use percentages when you talk about a drop in temperature on the Celsius scale.
Impressive that you thought of that
it should temperature difference against room temp, then it can use percentage.
Hi! I am the guy requesting help with a
Silent build under the last video. This video really helped me figure out some stuff before making my purchase. Just wanted to thank you for the immense effort you obviously invest in your video! I really think you will blow up and become really big if you keep at it with the same effort!
Exotic Butters Thank you for the kind words! Glad the video was of help to you.
Thanks for the video.
Very great results!
I undervolted my Alienware 13 R3 i7-7700HQ by -140 mv (stayed stable throughout all stress tests). It used to reach temps of 94 degrees Celsius during heaving gaming. Now it maxes out at 80 degrees! It was like buying a new laptop. Another thing is that the GPU temps are now much lower too. I think it might have the same heatpipe as the CPU or something like that. It used to reach 87 degrees.. now it maxes out at 80. Idle temps also dropped from 54 to 42. My battery life was also increased by around 45 mins. If you haven't done this yet, go do it now..
A very interesting topic for discussion. well done!
Is there also an opposite of this, where you increase your clock speed as much as possible without increasing the voltage?
Undervolting is even more crucial in laptops where the size of the heatsinks and fans is very limited. Therefore if the CPU runs cooler the clock speed can get even higher (closer to the stock speed) since the system do not over heat at all even under heavy load like 4K rendering. Also your CPU drains less power and therefore your you can squeeze a bit more operating time from your battery.
A very good and very sensible video, I understand gamers in the pursuit of maximum performance but there are a vast number of tasks where continuity and reliability matter. I regularly process video with ffmpeg that uses all cores and threads and you want stability and reliability over peak performance.
I’m not even joking I won the silicon lottery got my Ryzen 5 2600 from 1.13v at 3400mhz base clock to 0.95v did multiple stress test like Aida64, blender renders, unigen heaven 100% stable. I also undervolted my gpu from which has been factory oc rx 5500xt btw from 1145mv down to 1045mv
Bro thats awesome
I use amd overdrive for my amd A10-5750m processor base clock at 2.5ghz with 0.88v 2.8ghz with 0.925v 3.2ghz with 1.050v and 3.5 with 1.187v.
Temps and ghz before around 90C and throtheling at 1.49ghz. Under load.
Temps and ghz now around 75C and turbo at 3 up to the full 3.5ghz! From zero to Hero!
MSI laptop btw
so overclocking with this undervoltage is safe for my laptop?
I have a pavilion gaming and it was going 95, 97 and even 99c sometimes. After undervoting I am now sitting around 77 to at most 83c for even the most demanding titles.
Edit: that's the cpu not gpu. Cpu seems to overheat much more than gpu in my experience at least.
Thanks for the good video and explanations mate :) I wanted to know if undervolting has an influence on the performance or something. Now I got the answer: No. As long as I don't change the clockspeed/multiplier and just change the voltage of the cpu/vcor downwards, the performance will stay the same.
on a desktop if definitely wont hurt, but with a laptop all it does is help! you get cooler temps, quieter fans, AND better battery life. i added over an hour to my laptop with 150mv undervolt
this is a very nice tip... undervolting CPU will allow for less power draw, noise and temp.
Too bad Intel locks their CPUs so i3 mini itx rigs (which would be great candidates for undervolt in mini-itx rigs) are out of the question.
I do not know how well would it work on AMD Ryzen 3s, and i have my doubt about if there's a need to turn off any turbo technology on the CPU in order to gain stability when undervolting (that will hurt performance). But since most CPUs have a safety overvolt in order to work with any shitty PSU, i think there is a chance of reducing voltage (at least a little) on any CPU if rig allows. And that's not only for new tech rigs, AM3+ FM2 and any older LGA from both intel and amd can be undervolted at least a little
I have a i7 6700 and it runs with core voltage in 0.990V. I did undervolting and I recommend. I never saw my chip overcome 49 degrees, even at 100% for hours!
i got ban from live stream chat, he asked how to reduce heat, so I recommended undervolting, and his fans say don't it's gonna fry the CPU, then he was like "YA BRO I AINT DOING IT TROLL" I'm just speechless
Who?
Henrry The Gamer this streamer name Antt, he’s using threadripper yet doesn’t know shit 😂
Ok 1 question, if we can lower the voltage of the CPU and get the same performance(clockspeed) and low temp, then why are the intel's CPU did'nt set its own voltage at that level for more efficiency?
Because not every CPU will behave similarly with under volt or over volt. The default voltage rating is the value which they promise their CPU to work with deterministic result.
I have nvidia rtx 2060 and i just went down from 1.1375V to 0.95V. Temp on stress tests dropped from ~48C all the way down to ~37C. Maintained stability. Thanks for the advice ;)
Nice video and interesting data. Almost seems like engineers have taken a lazy safety margin above the bottom instability point and are operating in a higher wear area maybe even.
You can TOTALLY undervolt your locked Intel CPUs. I built a SFF PC for my bro about a year ago with an i5 4460 in a GA-B85N- Phoenix motherboard, and the Arctic Freezer 11 LP I bought for it was a bit too loud, so I undervolted the CPU in the UEFI. I was very easy. 100% recommended.
I did it. lower temperature same game performance! why no one talks about it?
@4:05 the 100% and 80% fan speeds, did you have to adjust the fan curve to do that too? Or will it hit those rpm/percentages based on stock fan curve?
So smart!!i didn’t know it could happen never tried it before I am always driving my cpus over the stock voltage just because I can and I don’t really care if the chip dies..but for home theater setups or just a daily office pc that would be nice because you can save on repairs (maybe)!!
Yes, you should, especially if your cpu fan gets really loud, the temperatures go insanely high, or if you are on a laptop.
I'm impress by this channel, subscribing. generic channels always offer bleeding edge tech, I'm interested in efficiency.
is there any correlation between how well a given chip can undervolt while remaining stable and its ability to overclock?
Update - just got a Coffee Lake that the board says needs 1.205 V at 4 GHz... runs fine at 1.01 V.
So low I can't use offset voltage because the idle would be less than 0.5 V :P.
I undervolted a socket A 2400+ with an overclock to 3000+ speed 15 years ago max temp under load is 38C and still running perfectly
Bro undervolting helps at long game sessions.
Yes it does I just got into pc gaming with ryzen 7 4800h and rtx 2060, in winter when we have like under 30c and as low as 19-24c at best, it was pretty good being able to keep its clocks nice and high, but now it's summer with 35c+ to 40-42c temps and lowest 33c, it was struggling and so I disabled the turbo (did not want to install ryzen controller) since I only play very GPU intensive games or games like valorant which give 144+ fps while cpu throttling anyways, it's pretty good under 85c most of the time. While boosting it almost immediately reaches 95c, but you gotta give it to those ryzen chips man, at idle it's literally averaging 45c it's crazy like just 8c over the ambient.
@@Varad13Plays 85°C - 100°C range is pretty damn toasty for those Ryzen chips my dude 😬 they will definitely start thermal throttling with that range under load. Try everything ya can to get it cooler!
@@TheNightKing22 chips are rated to not throttle till 105c man and asus has done a bad job with its cooling, I am going to cut vents into the bottom panel and add some copper heatsinks on, replace the thermal paste then it should be better
@@Varad13Plays well you're right the actual limit for the 4800h is 105° but it does depend on which chips we're talking about where they actually start limiting. Still! CPU and GPU dies are not super stoked to be running close to those Temps, and in theory could shorten lifespan of course. Are you running an air cooler?
@@TheNightKing22 no its a fully custom loop with a 360mm rad
I bought an i5-6600K and the Z170 Platform in the thought that I'd like to get into overclocking. Have played around with it briefly once but haven't had anything consistent simply because it being stock was more than enough than what I needed it for, especially in games. I'll probably start overclocking when the 6600K starts to bottleneck other components which hopefully won't be for a fair while.
3:30 that's not 10%, it's actually 17%
the ambient temperature is 21c, so the delta from ambient was just 30 degrees. you're not trying to cool ice here to sub-zero temperatures here.
besides, if you're going for absolute values, temperatures start at -273.15 C, not zero.
Great idea for the tiny dan case a4.
I'm using i3 6006u 2.00GHz and testing -0,100v right now... Is it okay to undervolt my cpu ?
Actually, I believe that undervolting CPUs and GPUs, while remaining stable, could possibly increase perfomance, as your getting lower temps, which means clockboosts will be more agressive :D
It actually does by almost 250%
damn am 4.9ghz 1.354V stable with my i7 7700k, can't wait for delid tool to come. At stock settings its around 1.18V.

Albin Keranović It will most likely degrade within a couple of months if you keep it at that voltage
So you are new to overclocking cpu if you said that.
You can have 1.52 volts max on 7700k (www.intel.com/content/www/us/en/processors/core/7th-gen-core-family-desktop-s-processor-lines-datasheet-vol-1.html). If you don't want to read it all you have a table at page 114, at 116 is for intel graphic chip.
I am currently 1.375V on 5GHz after delid. Temps are now 70C max in prime95. I can hit 5.1GHz after delid, but i must put 1.48V to get it stable (prime95 86C max), so its a poorer chip, some can get 5.2ghz at 1.44V. So i have backed up because its a slow boost 100mhz for that much more voltage.
1.52V is apsolute max for 7700k, so its not safe (its like living on edge), but everything belove 1.5V is ok if you can keep temps belove 85C.
Above 90C 24/7 will degrade your intel 7th generation cpu, but very slowely 2-3years maybe more, it depends on certain cpu, every cpu is different, and depends what are you using your cpu for.
I had fx8370e at 4.8ghz at 1.5V 24/7 (max temp 55C) for year and half, no degrade, every bench test was equal all the time, now my dad is using it, everything works as it should be.
Btw you must have a great motherboard so the power delivery and vrms can keep up. Only poor motherboard, or faulty motherboard can degrade your cpu at voltages lower then 1.4V, if the temps are at normal lvl.
I will contact you in couple of months if everything is fine with my cpu, so that people know for sure. ;)
Albin Keranović so how has it gone?
49ghz @ 1.35 for me I see no point to delid
@@hasanenhaider1060 they have water coolers that go straight onto the processing chip under the lid that keep them icy cool with massive overclocks.
This channel reminds me of the cold fusion channel!
I actually did something like this with my R5 1600 since I got it. 3.2-3.6(turbo) speed, 1.118-1.4V vcore, which is waaay too much for the turbo mode. So I just manually set the whole thing to 3.6 ghz on all core and fixed the vcore at 1.2V - speed is way better, temps are somewhat cooler, and the most notable part: I measured 82W total system consumption while watching a 1080p60fps youtube video on default, and by fixing the vcore it dropped to 71W. Pretty neat.
have you tried an oc at 1.35v?
3:35 did he just say 10% decrease? 10% decrease in degrees Celsius? Not the most scientific observation considering a difference in Kelvin is more meaningful measure of temperature
How to undervolt Ryzen 5 3600X? What voltage I should start offsetting from? The clock speed is dynamic so voltage is too.
i actually did that with my 4790k, 4.4Ghz 1.21v, at stock it was pushing 1.32v at the same frequency
Question: can you not under volt a stock processor? Why buy the unlocked version if you're not going to over clock? Resellability?
You have a very good CPU. Running Heaven benchmark my CPU drew as much as 1.368 volts at stock speed [not overclocked] and it fails to finish POST at 1.2 volts. [Edit] I forgot to mention maximum core temperature was 54 degrees C.
very nicely explained. thanks.
I would suggest overclocking as much as possible at stock voltage if the CPU is well binned, thus overvolted from the get go.
I undervolt my i5 4200 u.after it crash it can’t startup on my laptop
Please help me
i think u undervolted it too far, try something like 80mV or 70mV
Probably you undervolted to a point that the laptop can't get enough voltage to boot up. Try plug in the charger and boot it up

How does undervolting play out with Ohms law? If the voltage (U) is reduced and the resistance (R) reasonably is the same because you're not actually replacing resistors or anything physical within the laptop, the Amperage I would reasonably give a lower amperage as U=R*I can be balanced so that I=U/R meaning that a lower voltage results in a lower amperage.
Is it simply that undervolting is adjusting very small amounts (in the 50-100mV range) means there aren't and substantial differences in amperage or is it something else i'm missing?
worked for me on ly ROG ASUS laptop...about -5C after i down volted it to -0.080v
I accidentally overvolted my laptop by .135, am I screwed? I undervolted it later. Did it cause damage? Warrenty void?
I've done this, i have a 7700k and a MSI Z270,
I was putting in auto mode running in stock Ghz, that turns to 1.288 on Vcore... my cpu was getting 80-85 Cº on full load... So now i set the vcore on 1.118 and Load Line Calibration on level 3 (that's push to 1.160) and my cpu now only reachs 65cº its a huge difference... and also its not delided
My 7600 survived the Prime95 with a 150 mV undervolting. However, it crashes occasionally at idle. Thus I only got a stable 100 mV undervolting.
I think this is the drawback of an "offset" undervolting. 1.2 to 1.05 is fine. 1.0 to 0.85 results in crashes.
My 2014 Macbook Pro laptop I have to undervolt and run custom fan profile to avoid constant overheating when playing computer games on it... With under volting it can run full 3,4Ghz boost 100% of the time with all 4 CPU cores at full load :) Without the under volting it overheats and throttles CPU speed down badly just from running GTA V at 40% CPU load usung GTX 980ti external graphics card...
Managed to offset my cpu core & cache by -75mV. Doesn't really help much on intense workloads as it still hovers more than 80°C even when turbo boost is disabled on my core i5 7200U @ 2.7-3.1GHz. Must be the slow and weak single 3000RPM fan on my laptop.
Here I7 3770 overclocked and undervolted, offset - 0.015 @4.1 ghz all cores, at stock speed should reach lower voltage than -0.015, but I do not want to do stability testing again
3:24 I think you mean -1.5% in temperature. Celsius is not an absolute scale, it's nonsense to talk percentage in C. For example, if it had gone from 0 celsius to 1celsius, you wouldn't say "+infinity percent" ^^
he actually means -17% because the lowest temperature an air cooler could possibly achieve is ambient temp.
the temperature of the cpu is the difference from the end temperature from the ambient temperature. 51c-21c = 30c
5.1 is 17% of that.
Thanks! That's way better :D
Rankin if your an american because rankine is based of the Fahrenheit scale
Eratz Leretour What nonsense. If you compare two absolute numbers of the same physical unit you can always make a percent comparison.
Yes, but while 12 is 20% higher than 10, saying 12°C is 20% hotter than 10°C would be completely inappropriate and misleading (take the example of 0°C and 1°C if you're not convinced). But GraveUypo brought a good light on the matter I think.
Just realized I've been running 20mins on Prime95 max heat mode testing undervolted temps before checking this video out :D
This is Electronics 101 + or - 10% on all values. Voltage, resistance, capacitance, etc. Though with digital and precision circuits a well regulated voltage with minimal deviation from the recommended spec is obviously most ideal.
AMD Phenom II 965 BE C3 stock 3.4ghz 1.376v daily use undervolted 1.264v and 3.7ghz oc 44c full load temp or i can undervolt to 1.312 and 3.9ghz 51c full load temp. it's a thing for me from 2010. Only Ubisoft(Denuvo) with Far Cry 5 and AC Origin force my hand to upgrade my golden chip to newer gen because lack of SSE4.2 instruction set otherwise i can play all released games and enjoy not just play to date with 8gb ram and a gtx 970 at 1080p at high settings or above some at ~40fps some above 60fps but usually i use adaptive vsync to get rid of screen tearing so 60fps with neat details its more than enough for my ancient tech.

you should always have the lowest possible voltage for you desired cpu speed, so the answer is always yes.
for noise consideration you can run a 6700k at 1.28 volt with a noctua d15 cooler at 800rpm with no cores going over 70c.
so i think any of the 2 latest cpus from intel can be cooled quietly with an overclock.
Also laptops made a very good use of undervolting; 10°c reduction on mine at least
How much less power does it consume when undervolted?
