Hi Guys,
Some help please...
Running 2 x 6990's in crossfire mode on Win 7 64.
3 cores are running @ about 350mh/s each but have one core that runs @ 125mh/s only.
I have noticed that when running Diablo miner I get 8 CU on the core instead of 24 CU on the other 3.
MSI Afterburner reports the core at 99% capacity but only reaches 55C temp... this surely is not running properly.
I think that it maybe a faulty core but just checking with you guys that you have not come across this before.
Any ideas?

Best
D
