I'm beginning to think at least one of my 7970ms aren't functioning properly. I was getting bluescreens pointing at the display driver till I did a reinstall of the OS. Formerly functioning driver versions wont install, I've only been able to use the windows update driver, 13.9 I believe, and the latest CCC 15.3 mar 20 beta on windows 8.1. Windows 7 I can use the whql omega driver or latest beta, though I can't get the second gpu to come online. It always returns a code 13 error, not enough resources, fresh windows 7 install. On top of all that, the best firestrike score I've ever gotten is 7765.... Scores just stay the same (~3-5% variance) regardless of GPU overclock. I'm at a loss. Short of just buying new cards. Anyone ever encountered this or have any ideas? AMD Radeon HD 7970M video card benchmark result - Intel Core i7-2920XM Processor,Alienware M18xR1
