Yea, one of my rigs has 2 cards, one of them is runing with 15kh/s oO and the other one with 140kh/s. Any idea whats up?
I get weird and terribly low hashrates when I've got threads set wrong on my 270Xs, other than that, no, no idea.
Post your config and maybe someone can spot it for you. I'm heading out for the weekend, so please don't take my lack of help as a sign of disinterest! I just won't be on the forums much if at all until Tuesday. Best of luck!
