Anyone attempted to lower voltage on the lower clocks of the RTX 3000 series?

[Tired9]

Let's for example say a game only requires around 800mhz of my 3070; Sleeping Dogs: Definitive Edition with a cap of 85FPS only uses around 700-800mhz at 49-65 watts max.

So for this instance I would like to drop voltage in that area and just above, has anyone successfully manged this or are lower clocks more sensitive to voltage changes or maybe the opposite?

You can reduce various things using afterburner.

Doesn't Geforce drivers have an equivalent of Radeon Chill? It's got to better then messing around with voltages trying to tune it for a specific frame rate

I don’t think so, I think it’s MSI Afterburner for Nvidia.

For Nvidia cards, just undervolt and play.

The Radeon software is really good nowadays.

Lots of people on here under volt 3000 cards using a power curve, saves a fair bit of power for minimal performance loss. You could have different profiles for different games I guess.

Definitely underclock. Never fiddled with a gpu before this one, but an underclock is cooler for no noticeable difference.

There isn't an equivalent of Chill, but it does have the option to set a framerate in the drivers. But since @Tired9 mentioned it's already capped at 85fps in their example, I imagine framerate capping isn't what they're after.

Ideally what would be perfect for them is if nvidia allowed per game profiles for underclocking/undervolting, which AFAIK Radeon does but Geforce does not.

^+1. I did undervolt/clock my 3060ti because I could hear the fans. Also threw in a 170W power limit because it hardly ever hits that high and it's about the highest it can run without me finding the fans annoying. Afterburner only allows 5 profiles though doesn't it?

Yes you can achieve this through MSI Afterburner. Ctrl F brings up the curve and just set what you want say 1740-800 for example and test stability. I’ve done this since buying my 3090 at launch as these cards can get very hot at stock.

Thanks guys. I shall report back with my findings when I finish work.

Driver will already be using lower voltage for the lower clocks. Open up MSI AB and press ctrl F and it will bring up the voltage/frequency curve - you can modify it and attempt to make it even more efficient than stock like what many already do with an undervolt curve.
