Sorry guys, I still have problem with my GIGABYTE GV-R928XOC-3GD. I have three of these, each in separate machine.
With one, I am getting 130 khash/s (and I am happy with it). The other two have ~70 khash/s and I can not get any more out of them (I start getting HW errors). Do you have any clue what may be the problem?

Thanks in advance!
Here is my config for my 4 MSI 280Xs - hard to see why yours is under performing. Can you get a little more on the GPU clock? That seems to be the only difference.
