Hello,

i have rigs with 5x 7970 and 5x 7950 win 8

what you need?

First your cards need two 8 power pins, if dnt have, more as 4 cards need powered riser. In windows 8 for me working only catalyst 13.1 (only clean install) for more like 4 cards and cgminer without crash.

My all setup with 5x cards working without powered risers because all cards have 2x 8 power pins, mobo is M77 mpower. Many cards dnt have open all pcie slots without ivi bridge intel platform.

Hope it help and donate is welcome.
