I have a problem. I got an XFX 6850 card overclocked to 900 core clock and 1150 memory clock with SDK version 2.4 and driver version 11.4.
When I try to use poclmb, I can't get more than ~2 Mhash/s! But when I'm using DiabloMiner I get up to ~200 Mhash/s. Anybody know whats causing this?
You probably have the CPU selected as the device to mine with. Change your -d/--device setting. For SDK 2.4 device 0 should be the first GPU. (it's 1 on earlier SDK versions)
