Hi,
I just tried NIST5 GPU miner for the first time and even though I'm getting accepted shares they all got Diff 0.000/0.000 which seems a little odd to me.
Is this how it is supposed to work?
Also with my 280x I'm getting around 5.1 Mhash/s. Is this what I can expect from my GPU?
Also change intensity setting to 21.
FWIW I've tried every intensity between 16 and 23. By far the best for me is 18. Anything higher and my hashrate goes down. 13.4MH/s on a 7970. YMMV
