I have a 7900 xt from xfx, it's the merc 10 black edition. Every time I attempt to either auto undervolt or apply an undervolt it reverts to stock settings. When using the auto overclock feature it says "auto feature failed".
Wow, that worked. Never had a duel bios card before, thought the other one was for oh **bleep** moments only but I guess arguably this was one of those moments at least for my purposes. Thank you for your help!
