Unwider, do you have access to a CF system? CF is basically unusable with the overvolt/unofficial overclock settings right now. To detail the issues: 1. Even after going through registry and disabling all ULPS, the drivers crash and the screen freezes for 10 seconds when applying overclocks (though it does stick). 2. Once you overclock, the voltages and speeds get stuck at max. This is not because of disabling ULPS, either, as the cards ramp up and downlock fine with Afterburner turned off. 3. If you set up another profile with lower voltages, and then try to switch back, only the first GPU's voltages will be correct. 4. GPU1 and 2 are mislabeled. Again, this is using 6950CF with unlocked shaders only. Using official overclocks, everything works fine. Using unofficial overclocks and overvolt on first card only, everything is fine. So in short, there are a lot of CF issues. Hope that helps.
