The two i have flashed both could not accept full 6970 bios and had to use w1zards 6950 bios unlock. with no voltage changes at all both cards can hit 880 / 1375, but i found they dont like much beyond that. the problem is, the more you turn up the voltage the more they crash. using powertune to min / medium / max doesn't seem to help.

apart from that they run great at 880 / 1400 24/7.

edit: temps never got over 65C even in extended benchmarking or gaming.
