Undervolt your RTX 4090 in THE RIGHT WAY - Tutorial

Undervolting really seems to be the best option in terms of GPU optimization for the RTX 4000 series. Be it a 4090, 4080, 4070 Ti or even a 4060 Ti, I’d still recommend doing it.
If you do it properly, you’re gonna lose virtually 0 performance or even get an increase, while dramatically reducing heat and power consumption. You're gonna get much lower temperature if you it the right way!
Today we are featuring a Gigabyte RTX 4090 Palit Gamerock triple fan and using a 1000W 80 Plus Platinum Corsair PSU!
We used MSI Afterburner, here's the download link: www.msi.com/page/Afterburner
The software in the background is Heaven Benchmark, here's the link: benchmark.unigine.com/heaven

[@ImWateringPSUs]

Thanks a lot my man!

[@SAFFY7411]

This is a great guide. I think you can take your undervolt videos on to the next level by testing the GPU performance in Fire Strike or something and then testing the undervolt, delivering both stock and UV power figures in watts for the average Joe to understand as well as the graphics scores to compare. Taking things even further would be how Bryan did it with FPS charts. But I definitely do think upping the info on these guides will give you a good audience because you test a good variety of hardware to begin with in a non complicated way.

Got everything flowing smoothly until I started playing Destiny 2 again. the game would hard shut off my pc after about 5-10 minutes of playing. this is on a ryzen 7950x3d, rog strix x670e-e mobo, gigabyte 4090 oc with, 64gigs of trident z5 ram, and a corsair rm1200e psu. all the games i'd played i'd had no issue. heat was good. power draw was fine. until destiny. i found this video and followed your tutorial and i can say i haven't noticed a single performance issue and still holding around 250fps on destiny with max settings and zero crashes. appreciate the easy tutorial and explanation

[@Ureel2]

Subbed and Notifications turned ON! Very well executed video! I appreciate your respect for viewers time and your awareness about similar videos about this subject. Being able to put yourself in your audience shoes is very good skill, although im not sure if specializing your channel in pc building tips is best approach - maybe its fine at the beginning to get some community but imo think about diversifying it at some point (games, Ai, anime/other shows, commentary, maybe organize some fun tech tournaments with your subs, idk). Unless its just a hobby of course; I say all that because there are at least 2 big channels about pc's - linus tech tips and gamers nexus and it will be tough to become the third one. I detect some max power limit on this one ;) but maybe you will prove me wrong

[@ImWateringPSUs]

Thanks a LOT for the sub, for the feedback and for the advice! PC building is definitely a niche subject, but it’s my passion! I’ll definitely try to diversify as you say, it’s probably a good move business wise, but I can’t see myself stopping doing builds :)

[@hzalien001]

Keep in mind that different bins will have different voltage curves. My 4090 Strix has a really strange bin. At 900mv it can only manage 2500-ish clock speed, any higher it would crash, but the curve shoots up at 950mv and can clock to 2750. It also does 2950 at 1.05v stock voltage which is total madness. It appears that there are some bins that can do really high frequency at the higher voltages but sucks at undervolting. So the more reliable way to undervolt is to do +170 mhz on the whole curve (no matter what frequency you land at), and then pick a voltage you want to stick to and flaten the curve from there. I picked 950mv @2750 mhz, doing basically stock performance while drawing at most 380w in 3DMark Firestrike.

Followed the steps here, however the voltage/mhz curve on my FE didn't line up with his graph, moving my video card up to '2600' as mentioned was a much higher jump. So I dropped it to 2550 to be conservative on the raise. From there followed all the other instructions and this is what I've noticed: FFXIV - still getting 200-230 FPS in the same area I was getting before (4k + maximum settings), a 40-60 wattage drop AND.... the most important part. Coil Whine disappeared. A well earned like on the video from me.

Nice tut, bro. Doing this since my 3090FE. Many people do seem to fail to understand the logic behind this... What bothers me right now on my new KFA2 4090, is that the lowest vGPU seems to be 880mV. It is using that right now idle on the desktop @210MHZ. I wonder, if this is a decision of the board-maker. But on every 3D-load this seems irrelevant though... Happy tweaking!

Glad it was helpful! To check if it’s not too much yes, you’re looking at artifacting but you also need to test is going from +800 to +1300 produces a performance increase. If it doesn’t, no need to put +1300 as it might be slightly unstable

I’m really happy it was helpful! Thanks a lot for taking the time to write this! :) Heaven is only used to put some load on the card, I agree it’s not very good for stability testing!

[@Treeck57]

I know I've already done this before, but when I had my 3080 Ti before upgraded to a 4090. I had two different UV profiles because the one is for games that use Ray tracing. I did research and found out that Nvidia GPU's RTX cores are very sensitive to the gpu voltage. If you set it a bit too low voltage and games would just simply crashed. Just be aware about that. So I set it slightly higher volt but still less than what factory voltage was used to be set and i tested a couple RTX games and it ran solid without crashing. But for raster games that don't have RTX. So I have a quite lower voltage but can clock at higher and it ran for hours no problem. Right now is I haven't UV my 4090 yet, but I had to watch your video because i can't remember what shortcut keys to make clocks go flat line. So thank you for showing me for that.

This is gold! it makes it a 350tdp card, or you can choose to make it a 420tdp card with even higher power than it was at 500tdp!! Thanks a lot! Would be nice if you could make a similar video about undervolting 7800x3d

[@ImWateringPSUs]

Thanks a LOT for the donation, it helps the channel a ton 🙏 I’ll try to get the 7800X3D covered ASAP!

[@MicroWave233]

Great video, im trying to decide which profile to choose I don't mind a small performance drop (maybe 5 fps) for lots of saved power consumption. Would you recommend the 90 mv undervolt for this case?

[@ImWateringPSUs]

Personally yes, I think the 900mV one would be the best for your usecase!

[@Moerti84]

Hey! Thank you for this video! Im thinking about upgrading my built from a 3070TI to an MSI 4090. The only thing I was worried about, was the 450 watts since it seems to be quite a lot of power in the long run (power is expensive in europe :D ), and if my Corsair RM850x PSU will be good enough for it. What is the average max power that the card consumes after the undervolting? Thx for an answer and keep up the great work :)

[@damonm3]

Should be under 400w and I’m using an hx750i and have even run cp2077 at 133% max power and with only a 3 to 1 cable and still was pulling around 550w on the gpu only. I didn’t run it this way for long as I like to keep card under the 70°c mark and under 60% fan speed. Asus tuf non oc. I haven’t tried this uc yet but I’d just try it and monitor the card power in Hwmonitor.. can crl alt out of some games with them still running full power. Also furmark works if it’s in windowed mode. Just play around and please don’t worry about power being too much for your psu. It’s plenty even if you’re running intel haha… but you shouldn’t run intel imo unless you know specifically why you need it. 95+ % of ppl should be running an x3d either the am4 or 5…

[@ImWateringPSUs]

Late answer but here I am! I can definitely confirm that the 850W Corsair unit would be plenty for an undervolted RTX 4090! It should draw a maximum of 300W with the 900mV option

[@doczombiez]

Hello, I wanted say thanks for this guide. I subscribed, ain't going lie i'm not a huge computer guy when it comes to undervolting and overclocking. Main thing I wanted to do is decrease the temperature since it's summer and my pc feels like how it did in the xbox 360 console days a huge heat warmer that heats the whole room Do you have anymore tips that can push down temps more?

[@VALV3RD3]

Great video, thanks. Let me ask you, do you think I should undervolting my 4090 with lower values than you recommended? The 4090 msi faming trio seems to get only 2610 Mhz maximum core clock, so it wouldn't be a considerable undervolt with 2600 max, right?

[@ImWateringPSUs]

I'm glad I could help! I'd still recommend trying my values, but drop it to 2500Mhz if not stable!

[@donaldslayer]

I did a 900mv on my 2080 super, and also cleaned it, along with moving my rig into a new higher airflow case - dropped 30c on my temps

I've been having stutter with my 4090 and 7800X3D and it's been driving me nuts. Reformatted and clean installed - still there. Just tried this GPU undervolt using the performance mode guide at 975 volts and I think it improved it! Thanks man! If this long term has fixed my issue, I love you haha! EDIT: Nah still stutters, I am cursed. Was worth a shot though thanks anyway lol.

[@ImWateringPSUs]

Try to undervolt the R7 7800X3D as well, following my tutorial for the 7900X (they share the settings). Also for the GPU, try unlocking the power limit fully and set it to 900mV and 2500Mhz with no mem offset

[@rab3072]

@@ImWateringPSUs never noticed this reply. I figured it out. Was actually DisplayFusion which I use for managing the triple monitor setup. Turns out the stutter was I had a setting to auto hide the taskbar on just 1 of the monitors (I have in landscape and was hiding that taskbar since I rarely used it). Disabling this and having it visible at all times fixed the stutters. However, I do get crashes in Cyberpunk unless I go stock settings with he GPU. Noticed anything around this game being similar?

[@tomastrchalik6791]

​​​@@rab3072hi, cyberpunk really pushes GPU to limits, your problem is that you dont have what is called "stable undervolt".. when you undervolt lets say to 0.975 and try it in some game, it may seem that it lowered temp and watts! great! but when gpu is pushed to limits (cyberpunk with RT), gpu will crash BECAUSE it doesnt have enough voltage (because undervolt) - SOLUTION is to raise voltage OR lower frequency. Try both, see what works best for you! Edit: i just looked video, its very specific for HIS card, every card is little different, so yes, as i said, try 1v 2750mhz for example, it should be ok.. or. 0.975 and 2700mhz may work better, try and let me know

[@brianwilson594]

Thanks for the video. One issue however that I discovered the hard way. Going higher on ram speed is not necessarily better for FPS. Using your suggestions, I ran benchmarks in Timespy and the higher I went on memory, the LOWER my graphics score was each time. +1300mhz for example ended up offering worse performance than +1000mhz. This is apparently due to error correction that takes place on modern GPUs when ram is pushed too high. Many times, modern cards will keep running (not crash) at unstable memory speeds, but the performance suffers. Can you do a video on this topic? I think many people are not informed about it and would appreciate being shown how to find the “sweet spot” for memory OC.

[@andremessado7659]

1. ECC is not enabled by default on Nvidia GPU's, you have to enable it through Nvidia control panel. 2. Every card is different. I can Max my GPU's memory (4090 AERO) to 2000+ and still not see degradation in performance but its not stable. I run +1700 stable and get the best gains at this OC. 3. It is general practice and mentioned in many overclocking vid's from years and years ago that you OC until you either a.) GPU starts becoming unstable or b.) you start loosing performance. Maybe he assumed most people would understand to look for this already and is why he didn't mention it.

[@ImWateringPSUs]

Thanks for this comment. And thanks for the reply too! Yes I did assume people would double check with a benchmark, I’ll make a dedicated video about it!

Really smooth and legit guide! Before undervolt (Heaven benchmark): 391.8 fps, 9869, minfps: 72, maxfps: 779.8. And then WITH undervolt (Heaven benchmark): 374 fps, 9422, minfps: 61.2, maxfps: 742.7. So overall, that is a substantial difference, so now I'm thinking how to boost that score to have nearly the same performance as before (Asus TUF OC 4090). UPDATE: I feel like Heaven is an archaic benchmark anyhow, so I instead ran VRMark. Stock 4090 settings gave a score of 17946. Undervolted settings (second half of your video) gave a score of 17,901. Performance is almost identical to stock, so I'm pleased with that, honestly. I suspect that Heaven benchmark is so old that it gives inconsistent results (at times).

[@ShufflerBluey]

Amazing tutorial! thanks!!! Quick question, im running a Gigabyte 4090 master edition. With your "performance" settings, im getting 2750mhz @ 975v with +1300 on the memory. I'm only hitting 55 degrees and the card is whisper quiet. I feel like the GPU has alot more head room. Do you recommend any other settings, or stick with these settings?

Very good tutorial. I have bought a 4090 and I have a question. Should I change my source to 850, or so that I don't have to, should I make it UV so that it consumes less? Thank you very much for the great tutorial.

[@ImWateringPSUs]

I recommend 900mV as the best spot, but 850mV would work great as well if you’re willing to lower your clock speed a little. I definitely recommend doing it!

[@Kerzul1]

@@ImWateringPSUs I mean to say that my 850watt source will work for the 4090, or should I reduce the power so that that PSU is not short of power. Thanks!

[@kippz1337]

@@Kerzul1 To 850W from what? What CPU is used, how many SSDs at what capacity are built in, what efficiency does the PSU have, gaming only or do you run multi-core worloads on your CPU? Without detailed information it is impossible to give you proper advice.

[@leokrato]

My PC was shutting down every time I apply high definition textures in Adobe Substance Painter and the reason was my RTX 4090 is getting up to 400w, too much for my power supply capacity. After this undervolt, my consumption is about 280W and the PC stoped to shutting down when use real time render. Thank you!
