g1610 h61b 8G 270*6 doesnt work.
Only main card plug on pcie 16x can get 60k 4ch,98% GPU useage.
the others got 99% GPU useage at the first 2 senonds,and drop to 0.
it can run any other crypto like: scrypt,scrypt-N,X11 etc, use all 6 cards.
an other rig with 280*4 works fine, 110k 4ch per card.

what can cause this? i have another rig with exact same hardware that works! just ssd is dieffrent.
on the rigs that work i have nofee 1 and gpu usage stays on 65-70%. is it ok?
