I have a reference stock cooled Zotac GTX480 and it's OC'd @ 850/1025MHz w/ 1075mV..

And my card with a custom fan profile never hits 85C in Games/3DMark 11 etc in this HAF932 case..

So you have a better cooled card and you could push even further..

But notice that you'll hit a wall at some point when additional voltage will not have any effect on the OC..

And both cards would probably not clock the same so you'll need to back down to a freq of the worse clocking card..

CHEERS..

You guys are lucky. I can't get more than 800 out of mine. Anything higher and it will lock up ingame. I suspect the VRM is overheating but I can't find a VR004 to buy in canada.
