#Undervolt #Overclock #Ryzen - Навчання та стиль
Surprised not one person mentioned that we remove the latency penalty incurred by circumventing dynamic boost.... Enjoy!
I did notice that you were pushing the BIOS flashback on the back of the motherboard which is not the clear CMOS.
Because everyone has been bitching about it, before you proceed to GPU undervolt tutorial, please do a comparison benchmark of Curve Optimizer undervolting vs hard capping clock/voltage undervolting.
Better latency without turbo boost?
@@richardfarmer6570 Yeah I saw that too. This is my first time on this channel, and that in particular got me worried.
@@araisikewai yeah I think that's the best way too. Will make that happen.
Ryzen chips, especially the lower core chips are exceptionally good at undervolting. I left my 5600x at normal clock speeds whilst just lowering voltage. By doing so I managed to get my 5600X to run a R23 run at 4.6GHz with a -300mV undervolt. So whilst under stress it runs normal clock speeds at 990-1.06V. That’s a golden sample.
Do you recall if consumption changed? In my case I can only undervolt by 0.1125 (rock sample?), and it does run R23 at 4.35 instead of 4.0, but the R23 score is very comparable.
The only way I can reduce consumption seems to be with fixed speed (e.g. 4000 MHz).
@@danimagfernandesYou can either set a max power draw or use a negative offset for the frequency as well in pbo. I personally did the latter with a very conservative -100mv and it is doing great so far. Max clock speed went down a bit, but the main thing is that the power draw went from 70 to 58 or so and it can still downclock for better idle consumption
How much drop in temp?
Thank you for this! I did not see on any of these videos if I could keep the speed at stock ratio. Thanks to your comment I know I can.
I just did that and did a open benchmark test is says performing below expectations
I was literally thinking of looking up an undervolt guide this evening! More for the heat output than the electric bill, but saving money is always good. 😁 Looking forward to the graphics card guides as well, for sure!
Great tutorial video. Laid everything out nice and simple! Honestly, so few resources that are short sweet and to the point these days. And many written articles are either outdated or a bit wrong (usually just on user forums).
My GPU is undervolted and now, after watching this, my CPU will be too. Next adventure is the RAM timings which I want to bring down a little if I'm able...
thanks for the video ! cant wait for the rest !!! so excited !
Been using Bryan's OC tutorial for years. Really helped me setup my XEON E5-1680v2 on an ASUS P9X79 Pro. Temps-voltages...all good and stable (while air cooled) over the last 3 years.
Good that i found your video, it was dificult for me to undertsant because the other videos were with another bios, but with you i did understand it and it improved my temperatures amazingly
Great tutorial, undervoltong is really handy in sff cases aswell, when you can't fit a large cooler. Although alot of sff now supports aios. Would love some insight from you on the curve optimizer feature on amd cpus aswell.
Great results, looking forward to the Alder Lake testing.
Hi Bryan, i don't have as many settings in my budget bios as in your video. However, I did set a static 1.025v @ 4ghz in my bios and now get ~15c lower temps in games. Combined with an undervolt on my rx 6700xt, I've dramatically lowered system power consumption. Thanks tons for your fantastic tutorial videos.
Great guide!
A few stats for my 5800x in case anyone else is interested. All figures taken from cpuid (NOT the bios, on my msi board, a -0.025v offset resulted in a 0.23v delta!). dynamic boost had it going up to 4.7Ghz at stock, I locked it down to 4.4Ghz, any higher required significantly more voltage.
Stock - 1.3v - 145W package - 85c with my custom loop ramping up to full speed - 15200 points in cinebench
After - 1.07v - 97W package - 66c with my loop keeping all fans and pumps at minimum - 14900 points
I saw my board offered a 95W eco mode under the PBO settings, so thought I'd see if that did any better...
PBO 95W - 1.2v - 122W package - 78c with fans ramping up somewhat - 14900 points
It did MUCH worse!
Thankyou for keeping my PC super silent, even when gaming, I'm going to give your Nvidia underclocking guide a run through later to see if I can save some more power from my 3080ti.
Thanks for this info!
So your core voltage is 1.07 and your cpu ratio is 44x right ? Interesting, I will try it on my rig to see how it turns out
My Mainboard can PBO2, so I take a negative -30 on all cores. Then on all cores -125Mhz (because it boostet to 4.846Ghz on default) so thats on stable 4.716Ghz. PBO Limits disabled.
My temps are now 73°C max in Cinebench, from 83-84°C, with NO performance loss. I have the same performance (sometimes a little bit higher then default)
In gaming it was before 70-76°C and now ~55°C and 61°C max xDDD Thats so crazy.. Cooling is a 280mm (2x 140mm Fans) Radiator in the top. in front i have 3x 120mm and at the back 1x 120mm for good Airflow. Mainboard is a Gigabyte Aorus Elite V2. Easy Undervolt and 10-15°C better temps xD
Thanks for this video Brian. I have a 5500 I've yet to install so I'll follow this in the future.
great content as always 👏
I might have to give this a go, also looking forward to an in depth 3000 series undervolt guide!! I just got a brand new 3080 ti from NVidia after my first one died. I did follow an undervolt guide but it didn't go into the details, it was just set this curve and drag it down a bit.
Relatively small decreases in voltage can improve temperatures greatly. If you totally lost the silicon lottery even 40mv can help more towards cooling than switching to thermal grizzly kryonaut as a thermal interface.
YOU SAVED MY LIFE. THANK YOU. Brand new Custom build was running over 95C in games and with undervolting .12500 MV is a perfect sweet spot for me. Hovering around 70C while gaming now. Thank you so much.
Thanks Bryan! This is so helpful!
I'm switching from PBO to your method after watching this. Locked my 7600x to 5.2ghz all core at 1.2v (from 1.25) with a 100mv offset as well. Seems stable. Cinebench is just about as fast as with PBO boosting to 5.45ghz, but my power draw went from around 100w to 75w and temps are cooler. Should be snappier overall locked at 5.2 versus boosting between 4-5.4 GHz... Idle power draw maybe went up a few watts, but nothing crazy.
I'm pretty happy with 75w and high 50's temps at 5.2ghz.
Ability to undervolt doesn't necessarily translate to being able to use a cheaper MOBO and/or PSU. Since the quality of the power supplied to the cpu will directly translate to it's ability to hold a stable over/under clock. Cheaper PSUs will have more voltage-sag/dirtier-power and cheaper MOBOs will have fewer power phases. Those will reduce how far you can push things. The method for finding a stable reclock will be the same. You just wont be able to go as far.
@AmpEdition - Drawing less low quality power doesnt change the quality of the power.
Omg,Bryan that's the reason I've been followin' you all the time.This kind of videos.Regards from Serbia!
Video is unfortunately many months old, but still just want to thank you for this excellent guide. My newest 7700-build is great, but was running a bit hot and frequently pushing the fan-noise a bit more than I wanted. Now the temperatures have gone down a lot, so the fans are extremely quiet in game as well, and against all logic, gaming experience and all tested benchmarks are still as good as before. Double upvote.
Ryzen Master has the curve optimizer tool to do UV(=less power and temps) without losing performance. In order to consume less power, it is even easier to just power limit the CPU in the BIOS down to 45W (minimum) and keep the high single core boost. For Intel or old AMD CPUs though, this type of UV you showed in the video is the best one.
Unfortunately RM doesn't work on laptops:/
@@IM_MOUNTAIN Agreed! I lowered the figures Ryzen Master CO test per core suggested by 2 for the higher ones, iow the -30 to -28, -29 to -27 and system is stable.
@@giorx5 What CPU do you have, as I found, earlier today, that Ryzen Master does not support the Ryzen 5500.
@@bigj1454 I have a Ryzen 5 5600.
@@giorx5 After watching this video (because I have an unstable system at high load) and reading the comments, I tried the BIOS fix, but have a GIGABYTE Aurus Elite x570 motherboard and all the settings are in different places and maybe not labelled the same as in the Asus, so I scrapped that idea and just moved the Curve Optimiser to -5. Mainly because the CPU not supported in Ryzen Master as well. So far I passed all the stress tests in OCTT, and 4 hours in a game that crashed after 2 or 3. Crazy - I was thinking maybe the PSU was getting spikes in power draw and was/am thinking of swapping for a £200 upgerade with 1200W (nerly twice the recommended). but maybe it's all because of AMD/Gigasbyte settings that are too close to the edge of stability? Time will tell.
That is indeed very helpfull video , thank . Cant wait to try it on my CPU . Just one question . Is it necessary to lower the CPU frequency to try this method ?
Good guide. Well done as always.
After watching this tutorial, I somehow managed to get my Ryzen 7 5700X to a voltage of 1 Volt (it occasionally dips beneath a Volt), with a temperature of 35-52 degrees, depending on load, with an average wattage of just under 30 Watts!
Thank you so much, now I can actually use my computer in the summer and not have 33 degrees ambient temperature in my room at night!
I have the same CPU. it does not let me drop to .15 as well xd but damn! a lot of decrease from 78 to only 55W!
Can you share the parameters of your config please?. I need to compare something. Thanks...
What's the point of posting only power and thermal number without performance stats. You can unplug the PC and it draws 0 Watt.
What voltage and frenquency plz ?
@@mr.mok7I have my ryzen 5700x running 42.75@1.050v
On Ryzen you can change PPT to get lower total power draw, even though it's not technically undervolting it can help with temperatures in a similar way. You can also change the number of active cores (I forget what the setting is called) but it doesn't really improve power draw unless you're running less than half of the cores active.
Thank u, this was incredibely helpful.
Amazing video, nicely detailed! Even a novice like me got through it with better temps & power consumption.
Added bonus exact same bios. Running almost 10c cooler on aio & stable
Excellent this is going to come in handy for me
I used PBO with around 100mv offset, and manually limited power. CPU runs 100MHz faster all core, with ~20% less power. A note on cheap power supplies. They are likely to have higher voltage ripple, which makes undervolts more unstable. I also tend to get instability at idle, or after stopping a test so it is important to test all scenarios, and bump up voltage slightly if you have intermittent crashes.
Crashes probably because you didn’t reset cmo’s after messing with your memory timings. This is why you don’t watch dorks on UA-cam with failed IT careers talk you into electrical engineering. AMD fabric clocks by default are meant for sustainability. You can have a 5.0ghz oc but use 5 watts on idle. You are actually down tiering performance under volts, vs playing with voltage delivery. You are probably also using more power To render lighter work loads.
Thank you for this video. I've been lucky enough to lower my 5900x voltage from 1.500 by a .20 offset. Seems very stable so far. Idle temp is about 43C. Thanks again!
The real deal is: PBO2 in "Advanced" > set PBO limits to "off" > then open Curve Optimizer, set negative curve and try to get stability starting by 30
The point of this undervolting guide is to save on electricity. You need to set the PPT lower or else the PBO2 algorithm would just push core clocks higher (if there is still thermal headroom) without lowering power usage.
@@ailluinthethyra6139 then you fucking set PPT limit to 50W or so, jeez... and still get massive boost clocks in lower workloads, like gaming.
@@mroutcast8515 Little aggressive, but exactly right. This video is a little misinformative, as you *will* get the magic temp decreases, but less so at idle, and you'll lose a lot of performance if you're not slamming the CPU with full load constantly for your daily use case.
Is Curve optimizer only on Zen3?
Set it to 25 still crash.. 20 still crash.. 15 still like stock nothing special.. did i do wrong way?
thank you so much this was so helpful for me.
Great video and guide. Thorough and very easy to follow. I’ve got a question though. I just bought a 5800X (cooled by my trusty old Noctua NH-D15) that i’ve paired with my MSI B550-A Pro motherboard. If i don’t want to downclock the ”CPU Core Ratio” is there something else i should do or can i just skip that step in the Bios and still follow this guide, maybe don’t lower the ”VDDR CPU Offset Voltage” as much? Thanks in advance/ Isak
Thanks a lot. I've been trying multiple ways to undervolt my Ryzen 5900x and only yours gave me a successful result : - 15 degrees, - 40 watt (0.1 offset was the limit for me but it's quite efficient).
Cheers from France !
Brian, by setting a fixed 4Ghz, you actually increased power in idle. By default your CPU dropped to 3HGhz in idle at ~8W, but when fixed at 4Ghz it consumed ~12W in idle.. It's 4W difference, but it adds up over time, especially if you're like me and never switch off your PC.
Damn dude 4watts
@@mikeymaiku Well, if you're saving 23 watts 4 hours in a day, but then wasting 4 watts during other 20 hours, you tell me how much power you saved? Which was the purpose of the video.
4W 0-24 means 35kWh a year. 35kWh charge with an EV means 290km - 160km travel distance. 35kWh means ~ 3500 slice of baked toast bread. :)
what do you expect when this guide is on the level of The Verge PC building guide? 😏😂 - YES , that's how bad this guide is.
@@peki100 your litterally counting fractions of a penny, at some point there is a huge waste in counting this. if you want to save your 4w maybe buy a 10w minipc and just use streaming services for anything gaming related.
do you really care your paying a extra 20-30 cents a month because your pc is on? because me mining nonstop on a single rtx 3070 increased my monthly power cast by only 3 dollars, and i am using 150w vs your 4w saved. theres a point where you shouldnt care and highlighting the 4w savings in such a hilarious way makes me just laugh since... yes im sure anyone with a moderate pc can afford 4 watts of consumption on thier monthly power bill.
I have to disagree, setting the clockspeed to a fixed value on modern Zen CPU's is just simply bad advice because it disables PBO boosting entirely. You claim at 27:11 that it's a "very minor drop in performance... only 2 to 3%", but you choose to leave out any game, browser, or lightly threaded workload comparisons that would contradict you. This comes off as lazy.
There has been tons of documentation showing how good undervolting is on Ryzen, but your method... not so much. If your goal is simply power reduction you can adjust the EDC/PPT/TDC values for PBO and that will achieve the same sort of results while leaving the boost algorithm to do its thing. Similar power savings can also be achieved without losing any performance by undervolting and not touching the clockspeed as almost all Ryzen 3000/5000 series that I've seen can achieve around a 0.1 - 0.15v~ negative offset without much effort and in some cases you can gain performance because you reduce power(+heat) and allow the CPU to have more headroom to boost if it needs to. There are other methods like the Curve optimizer but those are not generally recommended for novice users.
exactly - games never load the CPU anywhere close to 100% so they take huge advantage of clock boost. I don't need lower power draw or temps on my R5 5600 so I just optimized for higher boost within stock PPT, TDC and EDC. Per core optimized undervolt curve, +200MHz max boost offset. Now in games it basically holds 4.65GHz (up from 4.45GHz stock at the same power draw), while in Cinebench R23 multicore is only about 4.35GHz (which can be obviously overcome by increasing stock power limits). If someone wants to reduce power draw (tho 30W will be still pennies in yearly bill) or temps - then do what I did and simply lower PPT limit to 50W. Then, with lighter workloads CPU will still boost higher than the stock but will never exceed PPT limit.
I was wondering why he wasn''t touching PBO at all? I thought maybe undervolting didn't play nice with it? But can you just keep PBO on and try a lower offset voltage while letting PBO do it's thing? Or is it even worth it?
@@IdiotRace I tried PBO along with undervolting and it caused some issues like CPUID could no longer detect my cores and Ryzen Master refused to load. For me at least it seems like one or the other but not both. (5600G)
You're right
His method is not optimal but still okey for low end mobos with stock cooler
Thanks for the effort! 😀
It seems like this (video's) undervolt approach is different from via PBO? Do they conflict? Do you need to disable anything from PBO? Mine PBO configs are all in default "Auto".
I had a PBO 2 curve optimization undervolt, which worked a bit hot but fine for a long time, because of many different reasons I recently encountered more heat problems which made it pretty unstable.
Now I just turned off PBO 2 and did some undervolting as in the video ("dynamic vcore" in gigabyte BIOS).
Quite a significant drop in Cinebench r23 (15000 to 14000) but in the few games I tested so far the performance drop is basically not noticeable and with way better temps.
Works great. Thanks.
Witch cpu did you use?
@@JaggersMusic R7 5800X
Great video! Can you use this menthod and use Curve Optimizer as well or is it just one or the other?
I had no access to PBO setting in bios so my option was to use pbotuner which doesnt retain settings between reboot. I only ever had to undervolt gpus so i was so lost. You really demystified the process. Thank you. My cpu is cool and happy in my shoe box sized PC case.
Finally thank you soo much 👍🏼
Good guide, like from Brazil!
A tip to those who want to start undervolt/overclock after an upgrade of CPU :
Clear CMOS after change of CPU before starting the undervolt/overclock journey.
Else you might get unstable error when testing.
So, setting UEFI to default is not enough?
I spent a couple hours with the curve optimiser on my 5900X system and had pretty good results. Went from the ludicrous 200 watts @ 85 celcius my Aorus master was pumping in to 145 watts @60 celcius and kept all the performance.
Pretty huge bump in efficiency there
Curve Optimiser is the best way to undervolt Ryzen.
@@Lord_RFAS It is more an overclock. With less voltage you get higher clocks until the core limit. PBO Limits are a wall, so it kinds of hold voltages and consumption. But yes it is a great way to get some performance with the same consumption.
You save my life thank you bro❤
Hey Brian thanks for the video! I use Asus X470 Gaming - F/3700X with .07500 MV for a perfect balance of performance and efficiency. I haven't taken it down further but it does go more. Temps in Cinebench R23 stay around 71C after 10 minutes of running. (noctua 12A with two fans) Maybe I should take it further? hmmm.
i can't wait to see part 2 whit undervolt of the rx 6700 xt ;) 200 watts to beat was my sweet spot for keeping it performing to my taste radeon chill do marvel by it self though for easier stuff to run.
Did got similar result in past whit r5 5600g granted was not using igpu portion was impressive too at 4.4 was keeping power under 45 watts too in my game probably would peak higher in that r23 though.
Nice content super relevante keep the good work was wondering what kind of cooling where you using my bet is wraith max cooler :P
Great video very helpful
Enjoyed watching this. Is there anyway to apply the offset to overclocking or PBO. I have had bettter experiences with manually tweaking that PBO.
Been rocking a 5800x for about 8 months, and when I first got put it in I was hitting 90C stock in CB20 on an NH-D15S. Figured out it was the setting's the mobo was applying (B450 Tomahawk Max). I messed around with PBO, and max was 85C-86C. Upgraded to an X570 Unify, and stock found its Mobo settings to be almost exactly what my PBO settings were on the B450, and again hitting 86C max. Leaving everything stock, except RAM profile, I added a negative voltage offset of .1V, and allowed the CPU to boost to whatever with that voltage offset. I did try lower voltages, but I started to get clock stretching, and my performance dropped considerably. With the .1V (-) offset temps are down to 72C max, using 20 less watts, and actually didn't lose any performance in CB20. Still boost to 4.8Ghz single core as well, but is much quieter doing so. lol Before while gaming, the 5800x was running louder and hotter on the NH-D15 than the 3080 12GB I got a couple of weeks ago. I checked paste and reseated the cooler a couple of times now, and came to the conclusion this thing just runs kinda warm. With the undervolt, on both the CPU and GPU, I hope it helps to keep my room a little cooler through this west Texas summer, but in the winter I do have my "heater" settings. lol
Aright, been experimenting a little more, and got my settings about locked it. I locked my 5800X to 4.6Ghz @ 1.29375V (Any lower and it was unstable) Scored 80 points less than my best score in CB20, while using 40W less power, and maxing at 67C from 86-87C. I think I'll take that trade off! Thanks for the video to help provide a little more understanding about how to extract the most out of these chips.
My 10900k was around 1.3-1.4 load voltage out of the box. I set static voltage to 1.34 @ 5.1GHZ all core (before vdroop - so 1.288v on load), 4.9ghz cache. Dropped from 90 to 60 degrees average in games and had a much better all core frequency. Though i lost 200mhz single thread which doesnt really matter to me.
We need more "how to" videos like this straight from your desktop ! 👍

what u write at the bios settings? please help
Maaan i tell you what. When i saw a 30min. video of yours (i already know how to undervolt ryzen) i was 'noooo, there's no way i'm gonna watch it, it's sooo long'. And it's a damn true man. All your videos, which involve easy steps, TAKE SO FREAKING LONG!
I have a 5800X undervolt -0.15 and power curve optimizer -15 =13136 multicore score. Down from 15113 max score but Temps maxed out at 65 with 30 min stability test. Temps was around 80 before.
That's crazy efficient. Although 4ghz is a little low for my 5700x and 4060ti combo. I pushed it to 4.55 @1.15v and it sips around 60w while gaming, stays at 60°C. I love these processors 2 years later
Hi I have a Ryzen 5700x aswell and I have high temps on some games. What did u set the core ratio to exactly as the vid shows 40.00 and how much voltage did u take away in the bios?
Games nowadays don't push the CPUs almost at all. Did you try stress tests for the cores? With 1.15V I can only achieve around 4350Mhz on full stress without getting any errors or resets. This on my 5600X. I run mine at 0.9V @3800Mhz for everything I do or 1.05V @4200Mhz when I game.
@@Sam_Bush These CPUS truly benefit from a good CPU-Cooler in case you want results. As I said above, mine runs at 4200Mhz full stressing cores with 1.05V and temps don't ever go above 60C. The original CPU-Cooler wasn't only noisy, but when you want results, it really throttles the CPU itself since it was going easily above 90C when I was trying 4400Mhz only with 1.2V. Nowadays, the smaller the lithography of the CPU, the more you're going to benefit from a good cooler. Also, you don't need an expensive one. Do a little research. The "Assassin" gives amazing results for a decent price. Easily outperforms extremely expensive coolers. Do your research, buy smartly.
@@Gyneco-Phobia Hi is my CPU cooler good enough. I got a nzxt 240mm kraken aio.
I have been searching to find out the idle power consumption of the Ryzen 5 5500 (or similar CPU) for days now without much success. I've read numerous written reviews also watched some other similar videos, and nothing. Now I just wanted to check how I can try to tune in some additional power saving settings, but I also found what I was looking for (package power ~10W or even less). So it seems the idle is pretty good on this R5 5500, my R3 3100 consumes more than 2 times that in Energy saving mode (~25W) which is already down from the normal mode(30+ W, way too much imho), so I guess this means it makes sense for me to buy an R5 5500 to save on energy bills. Great video, thanks.
That was very usefull tyvm!!!!
How does this compare to pbo on your test cpu? Great video
Would have been nice to see before and after results for games rather than synthetic benchmarks, sure you didn’t crash during Apex but how much real world performance did you lose in Apex? Synthetic benchmarks don’t really mean much as far as gaming is concerned. I took 80w and 10 degrees Celsius out of my 3070(gpu) and only lost 5fps. My fans run slower as well. Definitely noticed how much less heat in in the room. As for my 5600x(cpu) it’s water cooled so I run it with PBO enabled +200mhz and let it do its thing. Playing Warzone so I need all the processing power I can get.
Hey yes man, Nice video btw, I have a Ryzen 7 1700 on my X370 board and im looking to upgrade, do you think that Ryzen 5 5500 is a good cpu, I'm not concerned about pcie 4.0 (i know 5500 lacks it but still my board can't support it so it's whatever) I'm doing some gaming/video editing, and I'm looking for an all around good cpu (my 1700 has low ipc), respond asap, love your videos
On my ryzen 5700X I have managed to set 4.2Ghz @ 1.05V. I advise you to use OCCT, it is more aggressive than cinebench. With cinebench it had no errors up to 1.02V, but with occt it did, because this is more aggressive stressing the CPU.
Amazing video Brian 👍 can you do a video for the 5800 X cpu
Nice job!
Pretty good guide and it's not too far off of how i do it. I still usually leave the multiplier to Auto and as others have said, pretty much just maxing out the negative curve optimizer will boost the multi-core score. I also go for the max PBO core boost clock (+200) on these lower end Ryzens. I just rebuilt my sons computer using the 5600 and it's rock-solid and only consuming around 70W at max boost. My only other recommendation is to also undervolt the SOC. You don't get as much benefit as you do optimizing the vcore but if you're in for a penny, might as well be in for the pound.
I'd also like to see you take a stab at a DRAM tuning guide. I am currently running through tuning my 5800X3D and the uplift in graphics performance is pronounced (350 point delta in Timespy). My aggressive 3200 Mhz tuning (CL13+very low sub-timings) is currently outperforming the 4000Mhz profile I had setup previously (CL17+ not quite as tightly tuned sub-timings) and the lower RAM speed has the benefit of requiring you to pump less voltage into the SOC. It might be too much for a video since there are SOO many sub-timings to modify but you can streamline the tuning by just using so simple shortcuts (like only dropping by 1 on single digit timings, 2 on timings in the 10-20 range and so on).
I undervolted my R7 2700X with an offset of -0.11250V and saved 43W at max while running Cinebench 20, went from 133W to 90W. The score went from 3762 to 3718 so its hardly any perf drop. My CPU max temp went from 79C to 62C. this was the limit with my system though, any less voltage and it wouldn't post.
My older Zen2 Ryzen 9 3900X crashed at -0.15V offset undervolting at stock clock but runs stable at -0.1V offset. Left the clock alone to let the CPU ramp up the speed on demand as usual. Cinebench gave me 18400 points, not that bad for a system I build 2 1/2 years ago :)
If baseclock is enough for you, most Zen 2 and 3 CPU's can be undervolted to use around 50% power vs stock settings. Works wonders with my Ryzen 9 3950X (16c/32t CPU using 80W @max load, and running cool). Baseclock is plenty for most. I Can't feel any difference, other than my fans running silently, and not spinning up/down on dynamic CPU loads.
Great video of the golden cost do you have any measure numbers for the 7 5800x if so can you tell us
Wath setings you use for 5600x ?
Without undervolting you obtained the best frequency and performance or with undervolting?
For people with good cooling is necessary undervolting?
Thanks
Of 79-82°C to 57-59°C on ryzen 5600 whit cooler stock. Thanks. Reallt good video.
The performance is more stable now. No fps drops.
Went from 190W on my Ryzen 2700x to 130W. Thanks man.
Keep it up!
OC : @ 4Ghz, offset -0.1250V.
2700x is quite a power hog, isnt it hahah
ive been running it since 2018, beautiful cpu with its performance being to able to run full blast even on low-end mobos
I think undervolting with a slight underclock is the greatest thing to do to CPU's GPU's in desktops and in laptops too...especially in laptops, if you don't care about a few FPS loss that is probably unnoticeable anyway.
Setting maximum CPU power state to 99% on battery to disable boost clocks makes the world of difference to battery life.
@@jimtekkit This doesn’t work on my desktop running a 5800X.
@@christophervanzetta It should work don't know why you would.
Quick run down; R7 5800x default PBO + -30(curve optimizer) all core R23 score = ~15700-15800 @ 142W, ~82C (~20Cish ambient)
Locked the core clock to 4.6Ghz @ 1.2V R23 score = ~15500-15600 @ 108W, ~68C
Almost 25% less power for 2% less performance. You can't beat that by lowering the PPT.
Managed to undervolt my 5600g using your method (4.1ghz -200mv), and an ffmpeg benchmark encode comparison....
5600g auto = 1330.86s (33.02 fps)
5600g u/v = 1348.19s (32.60 fps)
Meanwhile my temperatures from stock cooler went from 77 deg C to 55 deg C. Perfect! I'm using Linux for this, but in windows i did notice i've shaved off ~ 30-35watts power at load. I think the idle watts were less noticable,, i'm not sure if it's placebo, but it seemed to idle from 20-25w, down to 15-20w. I will probably check this later with power drawn from the wall and see what the difference is there, but i'm pretty happy with the performance gains, thanks :)
@Tech YES City can you use the Ryzen Master app to change freq and volt as I have seen in some other vids but it seem they didn't get crazy drops in temp. Or is better to do all the adjusting in bios?
17:00 this part made me feel so much better about my pc. I got the 5800X and I was always at like 55-60c idle but my Gaming temps were spot on stock, so I changed my negative offset to - 0.3 from 1.42V and the 0.3 was purple and I read it was bad but you helped clarify that for me. Now I get idle temps of 35-40c with a 20c room temp. (even with the undervolt my gaming temps and performance are still great
I know you mentioned undervolting decreased performance but at this point I just want a stable PC haha. It runs faster than my old cpu, 1500X so Im happy lol
I just had my 5800x and having the same idle temps and with load it can reach up to 80c. i'll try undervolting soon and hopefully get a better temp. It's scary to see high temp on idle 😂
@@ziggyzig5666 same here with 5900x, doing this now until I can get better (and quieter) cooling for it
Will this work is in 5600h ?
thanks, a side i had not seen for ryzen! pardon the ignorance but, how does this go along with curve optimizer thing?
I got amazing result following yor video. I have the same cpu ryzen 5500.
My scores on cinebench are 10002 after undervolting by 0.200 . And the temps went down from 92 degrees to 71 with the stock cooler.
You mah boy! 😘
Thanx, finally got my 5900x undervolt manually to my needs (low power, intensive CPU use). Curve optimise was useless in my case. Ive set PBO disabled, manually set offset -0,05 (0,1 was not stable)4.2GHz 115W power consumption. BTW testing undervolting in static full throttle conditions could be ok (like in my case), but playing game is different story, GPU can spike as well, lowering rail voltage and left no headroom for undervoulted CPU. All depend of use and needs :)
Wow keep going bro
Do you have a stable setup for 3400g? Would be really helpful thank you
What about negative curve? Isn't that the better way to do it, if you're using 5000 series CPU? I personally did -30 on my 5600 and it works flawlessly (I'm cooling it with Wraith Spire @ 1200 RPM)
This is awesome! but there's nothing more frustrating or envious, than going in excited with undorvolting and then realizing your cpu is below average in terms of silicon lottery lol
I want to thank you because I knew very little about over and underclocking for the e past year. I’ve been running my CPU at 85 to 90 Celsius for the last year. I am now getting 68-70 degrees as well as better performance with my ryzen 5 5600X.
I am also getting a significant degrease in power consumption, going from 75W down to around 45W
Did you set all core ratio to 40 (4.0ghz) like his or let it auto (which is 3.8ghz base clock and 4.6ghz boost clock)?
@@hquan1 went from 4.6 default down to 4.0 like his
I've been curious about undervolting my laptop due to running it on a portal power bank at times. My goal is to undervolt my CPU in order to maximize my battery by lowering power consumption. My question to you is, is undervolting safe on laptops or even possible at that? Thanks for your content as always!
I use a program called HYDRA made by the guy who made the Ryzen DRAM calculator. Hated seeing my 5900X pull 110W while playing GPU-limited games. Configured it to pull about 75-80W instead. For me, it's more to control temps and for it to be more efficient than longevity, but they go hand in hand
Managed to get a stable undervolt on my ryzen 9 5900x on Asus x570 mini itx mb to -0.100 mv.
Max temps just under 60c with cores running at 62.44 W, package at 102.98 W which is about a 20% reduction. Not bad. Will keep these settings until I get a bsod.
Cinebench 23 gave me a score of 19448* about a 2% drop.
Fantastic tip and much appreciated ☺️👍
I had basically the same results with my 5900X and the same settings thats amazing
That's fantastic. Could you explain the steps to achieve this
@@mindrover777 hi mindrover777,
I basically followed
Yes Tech City's instructions using the first modest settings he described. Good luck with your attempt 👍
@@joviliro thanks 👍
Why the points were going slightly higher is that the CPU build in boost curve by AMD can boost longer on lower temperatures.
This is what all extreme overclockers do to achieve higher points, longer boost times are the hidden performance gem.
the clock was fixed dude
This is how misinformation is spread.
Hey mate, would this work with a Ryzen 3900x and GTX 1070 ti? After leaving Vietnam last year, finally getting around to getting my systems together. I'm using a classic Mac Pro for video editing and streaming, so this would help out with my gaming system I'm throwing together from used parts.
Is it ideal to undervolt the Ryzen 7 5800X ? I primarily game and content create on the machine. I just don't wanna lose gaming performance but the fact its reached 82C before concerns me
What settings will be good on ryzen7 5700x?
Great content, I need to undervolt my 5800xt to get it into an iTx build/case. But no mention of PBO undervolt or status. I was looking at a PBO UV of PPT 115W, TDC 90A, EDC 105 A? 🌈
Lovin' the content Brian. Seems to me Japan has recharged your batteries!
Do you recommend undervolt from Ryzen Master or BIOS for Ryzen 5000?
I have a R7 5700x and I've set my voltage to -0.102mv.
Got around 13k in Cinebench.
Temps around 50's and the performance is amazing. Thanks!!!
whats is the total power draw and will all 8 cores still function well in editing videos bro?
You have such a soothing voice, I'm straight but I would still prefer hearing yours than rougher voices. :) Plus great content!
Voltage doesn't affect performance right - only Power Draw and Temperature? Clock speed is what will give me higher/lower score in games/benchmarks?
In my case i did not want to lose any performance but while drawing the same or less power:
My final result with Ryzen 5 5600 (NON X) is: -0.075v at 4.3ghz, so... i only lose boost (around 140/150mhz), but the normal clock speed when rendering (wich was 4.25ghz at stock settings) ramped to 4.3...
Finally, my score was higher, around 300 points, my power draw was less, about 15W peak and same draw or less at idle, and my temps are 8°C less (max).
Nice and easy to follow tips in your video, i dont want to lose any performance in my case but its amazing what you can get with little tweaking in voltage mainly.
