Okay so I had 3 7950's running just fine in the slots the board has. It has an x16, x8, and x4 slots that I used and mined perfectly fine. I installed an aftermarket cooler on one of the cards, and when I installed it back into the board, only 2 cards were detected, the artic cooler GPU in the x16 slot and the regular reference card in the x4 slot, x8 wasn't detected. I then went ahead and one by one tried each card in each slot, and they all gave an output, everything working good having a card in the x16 slot and in the x8 slot, but once I installed the 3rd card in the x4 slot, the card in the x8 slot wasn't being detected. I'm not sure what happened, all I did was change the cooler on one of the cards and they would mine just fine before. I'd really appreciate any help.
I've already updated BIOS too.
