no matter what i do underclock the speed or mem or power . i even modified the power limit in the kgb.cfg file and set it back to the default 114% , i still get my power goes up to 293% and then crash whatever im on game or benchmark .

im not sure what am i missing , i've done what crazynutz said exactly , unlocking the bios worked with kgb and flashing the bios was a success .

anyone with MSI GTX660Ti PE unlocked bios that worked for them id love to try it out .
