DO NOT install 14.6 or 14.4. The last good for Radeon 7990 was 14.3 Beta 1.
STILL nothing but hw errors.. ANY other suggestions? Help would be GREATLY appreciated and rewarded
Have you tried lowering the worksize to 128?
THIS freaking worked! If you can, shoot me a pm with your wallet address whenever we are able to send coins. I'll hook you up! Thank you SO much! I have been DYING to mine Darkcoins, but I just could NOT get them to mine lol
