I installed the beta drivers and it basically ruined my system and I had to do a fresh install. I was getting blue screen but once I had removed the drivers in safe mode and attempted to install the normal ones the 2 6950 would show as 2 standard VGA controllers. I tried taking one out, using driver sweeper and so on. I gave up and re-installed windows.
Everything was fine by now when my cards are in crossfire they throttle up to maximum just on windows desktop. I have tried re-installing drivers and so on but now crossfire is enabled it OK. I have had crossfire working fine for months. Any help would be great.
