Hi,
I got a DIAMOND 7870 GHz Edition and a xfx 7870 double d in crossfire, in windows 8 with the original drivers, asus z77 pro 4, and a thermaltake psu 600w, it runs excellent.
But, whe I tried to upgrade the drivers, estable or beta any version, my second card (the one not connected to the monitor) is disabled. I have tried unistalling drivers, using amd cleanup util or driver fusion, disconect one card before installing the drivers, no removing the old drivers.
Is there something bad with my hardware or, it's an extra procedure for upgrade the drivers withhout reinstalling windows?
