So I got a 6800xt and I decided to try mining some ETH with it. The minimum voltage is 881mv on the stock card and I could lower it to that on the Radeon app, but I was still outputting 168W. I decided to download MorePowerTools and a 6800xt stock bios from techpowerup to undervolt the card even more. I tried 612mv and my screen froze, so I decided to return to the default undervolt of 881mv. Now, when I try to undervolt the card, any time it's under load it will freeze and reset the settings (previously I could undervolt it to 881mv with no issues). If I don't limit the power, the card is perfectly fine and gaming is okay. How do I change it back so that I can at least undervolt the card without freezing like before?
