I have a water cooled rig with a i5 and Asus Maximus board. Overkill..but I wanted to try a water cooled machine and I got it for a good price, used. It came with two 6950's and it was running steady for a couple weeks.... But for the search of more hash, I took out the 6950's and put in two watercooled 6990's with one watercooled 6950. I apologize for not having the exact motherboard model, but there are four pcie x16 and one partial pciex4 slots. I'm running windows 7 and I installed ATI 13.12. It's only recognizing the first 6990. So before a fresh windows install and trying different drivers I'd give BAMT a try.... Same problem... It's gotta be a motherboard problem... Right? What am I missing? I tried connecting the crossfire between both 6990's and no change in result.
Help!
Thanks
