Anyone know why this can be?

XMR - Total Speed: 5537 H/s, Total Shares: 1(0+1+0+0+0+0), Rejected: 0, Time: 00:00
XMR: GPU0 953 H/s, GPU1 953 H/s, GPU2 954 H/s, GPU3 770 H/s, GPU4 954 H/s, GPU5 953 H/s

Note the 770 (will go to 0 aswell), all same cards, all same bios all same clocks. With claymore 9.7 all fine. Anyone has an idea on how to crank this one up aswell?
