Does it artifact at that overclock? Must be something? I mean, youtube, the popular site on net, nothing?

If you buy into the ASIC thing I would say the 85 is better. 65 is pretty low. But saying that, my 70% card could do 1240 with set volts of 1.3 (actual 1.25) on air. So ASIC is not reliable.

If I were you, I would run each at 100% fan & @ 1.3v and bench CRYSIS on a loop for 30mins until you reach the max for each card. It will give you a decent guide I think. I would not push higher than 1.3v though, higher is for water.

Both my cards are low 70s ASIC

Same with my HD 7950.

Well, something happened to my Sapphire 7970 OC. Can't even make it through Heaven on stock clocks without the screen going black and sound looping. Not even 30 days old so I've got an RMA into Newegg and will be getting a replacement. *sigh*

Even reinstalled windows and tried the 12.7 drivers (was on 12.3), even without afterburner it still does it. FRUSTRATING!!!

Maybe your overclock had something to do with it?

Has anyone had their GPU core clock stuck at idle speeds even when they play games?

The pass few times I've played BF3 my core clocks been at 500 MHZ, other times it was fine, not too sure what's up with it.

Maybe... who knows... don't use it THAT much, and never got burning hot either. Crazy a card like this can degrade/burn up within 30 days of light use with that overclock (it's not THAT high). rolleyes.gif
