I just cant make my sapphires dual x 280x to work like it should.
4x280x is hashing at 1450hs.
Tryed to run just one and result is 360-365hs.
Win 7, 8gb, drivers r 13.12, virtual mem set to 16gb.
Interesting thing is that i have same results on 1100mhz and on 950mhz gpu core clock.
How can ppl run Asus on 450+ hs?
