I have two Diamond 7970s that ran in Crossfire on my P55 SLI mobo with Windows 7 Pro x64. Anyone having trouble getting it to work on the Z87 FTW? Windows for some reason is not detecting the second card in the second PCIE slot (8x), after a fresh install. (it's not the power supply, I have a 900 Watt Antec Crossfire certified PSU!) I think it may be a BIOS setting, but I'm lost in there and their on no guides for understanding the settings. Help!

    CCC is installed, but if Windows doesn't see the second card, makes no difference about the driver and bridge...been reseated several times. Thanks though.

    Curious, how many z87 FTW mobo users here actually have a functioning dual 7970  Crossfire setup? Please chime in...   ;-)

    Windows didn't see my second 570 long ago until I downloaded the drivers...
