I don't think you can add more voltage via a bios mod anymore since the geforce 6 series. The options are there when you edit the bios but it does nothing......at least with my 7800gtx It done nothing (tested with DMM)
Eitherway your gonna find out im sure.........
Are you gonna see if there's even more left in the 7950 GT 570M?????
