Well fried my card today messing with Trixx and Overclocking LOL.
Took it back and they gave me a Gigabyte card instead same clocks but stock voltage on this sucker.
Dude I have overclocked the living piss out of some many cards and never had that issue. The TriXX doesn't have enough voltage to fry them out. 1.30 is not much for these cards. They can go pretty safely to 1.40 with right temps. I had a set of 5770s that lived at 1.35 overclocked and benching all the time. My old GTX 295s were always going maxed. I think you either had a defective card or temps were outta control.
