I am having issues with the h81 pro btc motherboard. I am on windows 10 64 bit. My motherboard will not read the RAM in slot A, it only reads the RAM in slot b. I have double checked all my connections and downloaded all the latest drivers, disable the on board video and still can't get the mother board to read any of my r9 390 GPU. Any suggestions, Help please?
This is primarily a bitcoin forum - may I suggest you post to the proper vendor forums?
If I had to guess, I would say you have a bad motherboard. It happens.
