Been running 2.6 for a while but now a 1060 6gb card of mine is consistently giving me "incorrect eth share."  I switch to 2.7a, didn't help.  I've turned the card back to stock, 100% power +0 core +0 mem, still incorrect shares, I've swapped the card to a different PCI slot, no change.  I tried claymore and the card will mine fine and not get incorrect shares.
