So I just got all the parts for my quad 7950 mining rig, earlier than I expected
I set it all up and was mining away, each card doing over 500kh/s ltc mining, all looked good and sat that way for about an hour. I reboot the system and now one of my cards won't mine. 3 of them go at the right speed but one of them reports 97kh/s and doesn't accept any shares. It also will say connection problems every so often. I also get a lot of errors about display drivers stopped and recovering themselves and it doesn't seem to affect the miner. Was running 12.3 drivers and had no control center, now running 13.5beta2 drivers.
Does this sound like a driver issue or something else?
