I just set up bitcoin mining. i have a HD 6950 2GB @880/1375 and i use Bitcoincz mining. Is BitcoinCZ mining good or what would you suggest. i'm getting about 358.9 Mhash/s
I don't know much about Bitcoinz, but you should be able to get a bit more out of that card. Drop your memory clock down to the minimum and up your core clock higher. Each card is different but you should be able to get the core to at least 900. I've seen some that claim to have the core up to 1000 on these cards with 1.25v (the temps would probably be a bit high for 24/7 mining at that voltage though). Also, to get a bit more performance, you may be able to unlock the shaders. Anyways, just some things to think about.
