Hi, Does anyone have any success with using afterburner with a 6990m and undervolting? My GPU runs pretty hot (89ºC +) when i step it up even slightly so I would like to try and undervolt it. I don't really want to mess around flashing the bios and rather get a software app to do this. I tried using TriXX which is very user friendly, but the voltage slider was sadly locked, so thought i'd ask before i install afterburner just in case it's not possible. Cheers
