MSI GTX 570 Twin Frozr III P/E Safe Overclock?

[GussetPimp25]

Hey guys, I've been fiddling with my GTX 570, and I've got it to 900/1800/2000 with core voltage (mV) at 1.100v's tempuratures seem fine at 65C but, after say 30 minites or so of Battlefield 3 or Skyrim, It just crashes to desktop, no artifacts or anomolies, just crashes, so i dropped it to 875mhz, same thing happens. Have i got a shitty chip or am i being stupid somewhere, because these cards have been known to go higher within safe voltages.

Thanks again guys

I have mine at 875/1800/2100 and it is 100% stable. Idles normally at about 35c and load it will hit 60c some times.

Hmmm well, i shall be checking it on my mates asus gene IV mobo to see if thats the issue, but mine is stable at 825/1650/2020 and stock voltage so i havent a clue whats going on :S

Update- Well it does it on another mother board aswell, Ive messed with my RAM settings, set them to stock and it still plays up, you can't RMA a card for not overclocking right?
