I am at a loss and not sure where to turn. I have two Sapphire HD 5770's that I am trying to crossfire. Both devices are listed in the device manager and gpu-z. They both list in CCC 10.1 but the secondary is listed as disabled. I have them connected with two crossfire bridges and each does have the pcie power to them. Both cards work individually but I have no option to crossfire them or to enable the second card. Sapphire tech was basically no help. System specs are:
Asus M4A79XTD Evo mainboard
Athlon II x4 620
4 gb DDR3 OCZ Fatl1ty 1066
Sapphire Radeon HD 5770 (*2)
Diablotek 650 Watt Power supply
Windows 7 Ultimate 64bit
