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?
Since they are the same I use the same configuration. My problem is that if i start either one alone. It does reach 605. If I start em together They both reach 605 but after 2-3 minutes the gpu clock drops and the Voltage and the hash with them (drops to 520). It s the upper card and the the monitor is plugged in meaning the pcie is the most powerful. Also this card appears to have more temp (85C) than the one that works with max hash (75C). (but probably due to the limited space that it has to breath).
EDIT: I also saw the 2 next answers. Thanks I ll try to play with the H (althouh I doubt i ll see any difference).
