Mate any idea why although
I have 2 GTX 780 (and two cuda miners) one shows 520 khps and the other 605? Can it be that the one that the monitor is plugged loses hash power because of it? Any idea what is going on?
I have 3 GTX 780Ti in one PC and two of them hash 10-20 kHash/s less than the fastest one. I attribute this to subtle differences in the PCI express connectivity.
But 100 kHash/s difference - ouch? played with the -H options yet?
