Title: 4x 280x mining rig on Asrock 970ex4, windows 7 doesn't detect gpus Post by: Pompobit on January 10, 2014, 03:46:11 AM 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?
