but you can play further giving volts mate also i see you got an awesome PSU wish i had that you can have real fun with it...i have a low vid and im sharing the loop with the GTX285, higher vid quads require more volts but it's up to everyone if you decide to play with it, on the giga i pumped lots of volts and then my PSU starts shutting down i will swap for a corsair soon.
i benched it till 1,56vcore real / 1,75pll / 1,66vtt and 1,76 MCH and the 2x2 gskills till 2,4
Cheers :up:
