Basically I want to add more voltage to my 6950 while having powertune at +20%. Otherwise my clocks will fluctuate meaning my overclock is useless. I have tried modifying the bios with RBE but I get a bsod in windows. Even if I uninstall my ati drivers, once I reinstall them and restart I get a bsod. MSI afterburner does not have a powertune setting so I can't use that. Any help would be appreciated. My card is an MSI R6950 twin frozr ii.
