Alright, Im assuming Im missing something rather simple here so I'll make it concise.
I recently bought another 5770 in hopes to crossfire them, but Im having a lot of trouble getting this to work. My motherboard has two pci-e slots on it. One is listed as a pci-e x16 (PCIEX16) and the other is listed as pci-e x16 (PCIEX8). Now the problem lies in that whichever card is placed in the latter slot is not detected by windows device manager or CatalystCC. Both cards run beautifully in when placed in the (PCIEX16) slot so I know its not the card, and I have ample power running to each of the cards.
I thought it might be a faulty pci-e slot, but when I leave out a 6pin the motherboard beeps a warning and both cards power up and have their fans spin when everything is connected.
There's a couple things that threw me for a loop. HWmonitor, a hardware monitoring program I have, detects when both cards are seated even though windows device manager does not. I also tried booting with just a single card placed in the second slot and windows device manager detected <NO> display adapter whatsoever, and same with CCC.
Now this is really starting to bug me. Am i missing something really simple here? Bios options for pci-e slots are limited to which to use as the primary slot so Im out of ideas here.
Any help is greatly appreciated.
