Vmod problem - 6800 GT

[Knavinusa]

I used OmniExtremeEditFX to raise my 3D Voltage to 1.4V on my 6800 GT and the card flashed properly. The card runs all of my games and 3DMark03/05 without any problems, but once I try to run 3DMark01, it freezes completely within the first two seconds of the test and I have to do a hard reboot.

Can the card not handle this voltage? It's an eVGA 6800 GT @ 415/1120.

EDIT: I just tried running Source: VST and it's fine.
