The results may not be as significant, but there is no reason, not to try.įor every one who want to try this. on the title of the thread - in principle all of the above is not limited to high-end gpus. more performance.Ĭoming from the stock settings you can have both up to a certain point (so more performance AND less power consumption/temps) - but once you found the optimum - from there you can choose either way.Įdit: btw. More Efficiency/less power consumption vs. But you can of coure choose your trade off.
Your GPU running cooler is a positive side effect, that may prolong its life.
Afterburner is a great tool to safely optimize all those variables for your individual GPU (mainly with the curve editor). So from the same brand and type, one GPU may need 950 mV to push over 2 GHz at a given temperature and the next on may need only 925 mV. And the silicone lottery determins how energy efficient the gpu is in the first place. (GPU clock speed gain in % almost equals fps gain in % in case you wonder)Įdit: The reason that the cooling is relevant here, is that it the amount of voltage you need to sustain a certain clock speed depends on temperatue. Power Consumption is about 300W instead of 350W and Performance about +3% over stock settings. But it will go up to 2130 975mV when outside temperatures are not as high as they are now. Personally I run my 3080 at 2040MHz/925mV as a save stable daily driver. I absolutely agree with everything said above. Therefore their default Voltage/clock curve has a lot (A LOT) of safety margin.
Basically, they need to make sure, that every sub-par binned GPU is running without issues after beeing sold. The Core clock going a bit up is noticiable in fps? I'm in VR and every frame countsĪnd another question, how do you get the core clock go up while power going down? Thanks!īecause, more voltage gives more stability (in general) and nvidia has to account for the serial quality spread of the GPU they sell. Sorry for my ignorance, but what's the point to undervolt the GPU? For run with less power and get lower temps to extend GPU life? My 3090 usually gets hot (anyway, normal for this card).
