I got a Sapphire 6670 card a couple of days ago for gaming, development, but mostly to replace a geforce card in bitcoin mining. But to my surprise, even when the card reports 90Mhash, it also produces a lot of hardware errors and no mining at all. Switched to Windows, and found that the GPU-Z reports no OpenCL support! I tried with Catalyst 13.4, then with the updated version in Ubuntu 12.04 repos, but nothing. The card does not produces any result. Can somebody give me an idea about whats happening? Should I discard this 6670 and get something else?
No announcement yet.
