Hi,
I'm trying to let windows 7 32bit to detect all my 4 gpus (2x vapor-x 280x and 2x asus directCUII TOP 280x) with no luck.
I'm using 3x powered riser cables (1x to 16x) and 1 gpu directly attached to the motherboard (ASrock 970 extreme 4).
All I can get is having two cards detected, sometimes a get a third but windows sees it as a HD7900
I've no jumped the pins because I heard my mobo doesn't need that, but probably I'll give it a try...
Should not be a power issue, the risers are powered and my psu should be enough (1300W coolermaster gold)
Anyone with a similar configuration/mobo/gpus?
Which pins you used? With the dummy plugs?
