Yes, I know. I've used the original miner and the updated one. Works perfectly fine on my desktop with a 7850, but my 7950s do nothing but throw out hardware errors. I cannot figure out what the problem is.
I didn't give up. I didn't think it would be a driver issue. I had installed the 13.11 beta drivers mentioned earlier and got nowhere with them. I just tried 13.12 for the heck of it and now all is working well on the 7950s. Thanks for all the suggestions everyone, I do appreciate the help.
