I'm running 2 6950's at 925Mhz, no overvoltage, using Afterburner. Going past the 925 marks creates great inestability for the driver (most likely insufficient power) and crashes. Over 975 means BSOD. Got about 40MHs extra. Shaders are unlocked by the way.

What happens when you start pushing it up past 925? Does it downclock? Because once I get to 900ish it starts wavering back and forth between 880 or so and 900. If I push it higher it just downclocks even more. Do you have a 2gb or 1gb card? Also what kind of power supply? I have a 600W psu, and nothing is overclocked besides the 6950. Also what version of CCC are you using? Sorry for all the questions lol
