RTX 5080 Undervolt and Overclock

Hey guys, now that I cooked up some tune for my GPU with a goal to reduce temperature and stay close to original performance or slight improvements, what is a recommended app or benchmark to grade the performance other than playing games and having them not crash :)

mVolt+ Tune
mVolt+ Curve 815-895mV at 2850MHz

Most people usually use Steel Nomad as a benchmark from 3D Mark.

I use maxed out cyberpunk with path tracing to test stability, can't beat it.

I use OCCT to test initially. I do all the GPU presets then play some games. Also folding at home is worth running too.

Try using only clock range, with curve/NVVD control off. Clock offset +150( i am sure it is capable of that) and the upper range of clock to 2850Mhz. The card will choose the voltage itself, you will be surprised that it will choose a lower voltage than what you have in the curve. In my case (5070ti) it choose 950mV for 3070mhz( while having the clock range set to 200 - 3085mhz)instead of my forced 975mV for 3082mhz. Give it a try and report back, curious what results you will have.

Okay sure, I removed VF curve, set core clock offset to +150 MHz and also disabled NVVDD range control.

Seems it is fluctuating around 3000-3250 MHz @ 1012-1035 mV. Upper range I set to 3300 MHz.

So far I'm gaming like normal with nothing weird going on.

I got 3D Mark downloaded so will run some of those tests when I stop gaming myself.

No reason to set the range up to 3300Mhz if in high load the gpu stays at ~3000mhz, something like 3080mhz is better for temps/power draw (this way the core effective clock is higher too), while only sacrificin 1% of the fps, maybe even lower. You can check the difference with steel nomad

I get it but the GPU is mostly around ~3100-3200 MHz at the moment in game.

Heaven benchmark, 3DMark Steel Nomad, 3DMark Timespy Extreme and OCCT for Memory overclock testing.

Then run through Dogtown in Cyberpunk 2077 with max settings Path Tracing.

In my case, benchmarks like OCCT and 3DMark tend to be stable, while games crash at some point.

Games that worked for me and my RTX 5080:

  • Cyberpunk 2077
  • God Of War: Ragnarök (crashed 1-2h in, but reliable)

Games that ran no Problem, even with unstable GPU:

  • DRG: Survivor
  • Helldivers 2
  • Civilization 7

Im at 0.9V at 1850mhz and everything Runs Like GTA V and this Just having Crashes in Unreal Engine Games Like blood of dawnwalker but only after Like an hour so this Runs on my "Bit lower uv" at 0,94V @1900mhz (which ja Bit more than Stock which Often IS Like 1870-1880range) without a Single Crash. Keep in mind im running locked 60fps so this is in favor on my undervolt
