Today i update the driver to 12.6 beta, remove the includet sdk and install the 2.1 sdk.
Now the prob is, that cgminer seem to work with ~350mh/s, but there are no shares at all?!?
wtf...
2.1 sdk does NOT work with the newer 12.x drivers at all. They are simply incompatible I'm afraid.

Um. I use 12.1 driver and my 2.1 SDK works just fine.
Try breaking it with 12.4 Wink

I'd rather not fix what isn't broken, unless you'd like to pay for my mining downtime.

Duh as if I expect you to... I was just pointing out it's newer 12.x drivers that are problematic, as I had said in my post.

Assuming it's the same thing causing it...  I had this problem as well and have been scratching my head for days until someone pointed out it's due to some ULPS bug with the new drivers. Installed 12.3 and everything appears to be working fine..... Wink
