    It's possible. But at the moment everything's stable where it is, so I'm going to leave it alone.

    And turning off Catalyst AI fixed my problem with Warhead, still trying other things. I'm actually amazed how few games I have that actually stress this card.

    Anything below 55% fan speed will cause your card to lockup while running Furmark. This is pretty much the norm with the HD4870.
    Software readings are crap.

    Actually, even when my fan speed is allowed to ramp up to 100%, it still gets to 95c in furmark. I haven't let it run long enough to crash.

    Before I adjusted the fan speeds, it got up past 100.

    Take the side off your case & put a desk fan blowing in to it!
    Yes. One of the last commincations I had with Dave Hammock before he disappeared from the web was how a major brand single +12V rail PSU wasn't shutting down when shorted. We were literally arc welding with the PSU. Hopefully Dave's absense isn't due to the fact that he got over zealous with the welding.

    Alright, so almost everything plays nice now, except my original problem still seems to be happening. My game will hiccup, and it'll seem like a normal drop in framerate, as the music keeps going, etc, but then ctrl-alt-del doesn't work, and the capslock light won't turn on. It just freezes up like that. As far as I can tell, it's not actually heat related, as I have my fan adjusted so that it usually won't allow the temps past 80, and at the time it last happened I don't think the fan was running very loud. Over 65c it's very audible.

    RMA'ing it. Played Crysis Warhead for an hour, temps from 65-75 for all that time, quit, once my GPU cooled off got a BSOD. I'm tired of troubleshooting this, and I'm going to hope this was just this card.

    Could be your CPU OC or RAM.

    Welcome to the Faulty RV770 Club. Not a lot of membership benefits, and for some reason, people don't want to be in the club, but welcome nonetheless.

    Except both worked fine for at least 6 months...

    Although I guess they could have picked the exact time I swapped out my video card to fail. And then stopped failing when I put in this other graphics card.
