How (and why) you should undervolt your GPU - A step by step guide (Deep Learning/Gaming/Mining)

A video on how to undervolt which is especially useful for deep learning with multiple gpu setup/gaming/mining. Although since it's going to lower temps substantially I recommend it in general just for card longevity.

*UPDATE 2021-03-24:*
MSI Afterburner just updated how their GUI looks like but it's the exact same process just the buttons looks different and might be located slightly differently. You can still follow it without any issues (the important things in the video remain the same) but to make it easier you can go to Settings -> User Interface -> Look for skin and choose MSI Cyborg Afterburner Skin White by Drerex Design. Then it should be exactly as you see in the video.

One detail I forgot to mention that is super useful is when you open MSI Afterburner around the top right region there's a windows button and you should press this button to apply your undervolt profile at boot (press this after you've tested it like I showed in the video). Also on the right side of MSI Afterburner there is 5 different "Profile" where you can also save different presets that you've found to work well for your GPU.

*CORRECTIONS*
- I said microvolts but it's millivolts, my bad!

Absolutely the best step by step video I've seen regarding getting better temp's on the 3080 TI was constantly 80c now 65 -70, 850mw 1850 core clock, I appreciate it very much

I know this video is already 9 months old, but I just wanted to give my thanks to you for this step by step guide. It really helped me bring my laptop's temperature down from mid 80's - low 90s to 64-70 at it's highest. I'm using a MSI GE76 RAIDER with a Nvidia 3060 and I was worried I would have to deal with the high temperatures forever. You just gave a lot more time to this machine's life expectancy lmao. Thank you so much for the guide.

I can’t thank you enough. I’m new to pc gaming and was struggling with my gpu temps. This video gave me the courage to try undervolting. A+

[adamm]

Amazing guide. The numbered steps made it much easier to follow than other videos who just did things. Results below:

Minimum 40% less power consumption. Temperature down 18 degrees Celsius. And obviously much less loud since the fans don't have to work as hard to cool the GPU anymore. All this for 6% less performance. The GPU I was working with was a factory overclocked Zotac 2X sized 2060.

Thank you so much for the video!! You've made my life a little bit better and a lot less noisy :)

Edit: Turns out stability in unigen heaven doesnt exactly translate to other games haha. Had to adjust a bit after games started to crash. New numbers:

30% less power consumption, 15 degrees celcius less and obviously less noise than stock. 5-7% less performance

My GPU was pulling 1037mV. Fans just going crazy over hight temps. I have got it down to 900mV VERY stable and my temps have dropped 15c in some cases and 10c in most. Fans are quiet and even my CPU has dropped a few C from the cooler temps. Thank you for this guide. It was great! I had the same result about a 1% drop in performance but it is well worth the temps and quiet fans.

Literally the best video about undervolting! Great job!

Thank you so much, my GPU temps dropped from 80ºC to under 70ºC.

[jimforceus]

I was having temp issues with temps pushing 80-82. I replaced the thermal paste on the GPU and temps are now always below 70 at max voltage. Just another option that’s out there. I like your video- never thought about undervolting but it makes sense.

[seanstewart]

It took me about 5 minutes into this video to figure out where you’re from: I’m guessing, strongly, Sweden. You’ve got an amazing ear for English phonology. Bravo!

[spinster]

I honestly cant thank you enough, I got red dead 2 for my newly built pc with a 3080 and when i got into the game i noticed my temps were going as high as 76-80 celsius, and being a 3080 i was a bit nervous and didnt want it going that high for lets say 2-3hours at a time, so I decided to look into this undervolting thing and its saved me my sanity! My gpu now is at max 67-68 celsius while playing and i cant thank you enough for this video, its super easy to follow along and you explain everything nicely! Definitely earned a sub.

[Jodrco]

Thank you very much sir! I was so frustrated with my pc build. My 2080 was always running hot and fans were super loud. I tried changing the fans, opening the case, controlling the fan speed... nothing.
Undervolting was the solution for me. Even playing apex legends with 144fps the gpu never goes higher than 75° and the fans are super quiet. It’s like a whole new pc build.

This is amazing! Thank you again!

[ocgamer]

thank you for posting this. you got got my 3080 ti down from 78-70 @ ultra high settings down to 73-74. great video and appreciate that you did not rush through the tutorial and took your time.

[joshsabine]

Yeah just followed this guide... totally works.
Rtx 2700super.
Was 1830mhz at 1030mv at 80°c
Now 1860mhz at 925mv at 71°c

Also getting higher fps slightly and less stutter.

Many thanks

[kieranlantier]

never left a comment on a video before watching this one. my 1660ti was hitting 83 degrees on warzone and now its at 73. thank you so much for the easy to follow video!

[chriscab]

This is by far the best explanation yet. Great job. 👍

[NicolasSilvaVasault]

probably the best explanation on how to undervolt a gpu, by far the best video, seriously

[frankgadlin]

I’ve seen a lot of undervolt guides and this one is one of the best guides online. Thanks for your help

[GroLaX]

Tried undervolting on my ZOTAC GeForce RTX 3070 Ti Trinity OC using this guide, I didnt loose any performance to my surprise i gained performance.

At least when I was using Heaven Benchmark, the score got higher on 900 mV then not chaning mV at all.
Plus the temperature went from 76c ~ 65c.
Later on I tried some games like Baldurs Gate 3 and Final Fantasy 14.
On these games it got to 80c ~ 84c sometimes, now max is about 65 ~ 67c when it's on high load.
It makes the graphic card so quiet.




Super nice of you to show this thank you so much! You got my like!!

[mohrange]

super useful, thank you! I built my first PC with a 3070ti and followed your guide and noticed a reduction in temperature on the Heaven benchmark while maintaining performance. On gaming, the GPU runs now much cooler!

[abhingthalib]

You're a life saver men !!! i just bought rtx 3070 msi ventus 2x oc and my first game was shadow of tomb raider, and im so suprised with max setting (exc RT) and res almost 4k i got 79c temperatures !!! after using ur guide now max temps reduce to 67, thats crazy !!! hahaha.not cool enough maybe but im satisfied.i use 900 mv maybe i try 875 and 850 mv.

and the important thing im not find any performance decrease, since my refresh monitor only 60hz anyway hahaha.but the fps stable at 60 so im good.

thx again bro !!!
