I've got 3 gtx 1070s running. 2 get rate that one would expect (25 stock 30 OC) and 1 gets about 10-15mh less and I can't fathom why. Was pointed to these forums...hope someone can help. Win 10, creators update, cuda installed, current drivers, claymore 9.5 dual ETH+SIA
http://imgur.com/a/nwsDfI've also noticed my hashrate fluctuates like crazy on all 3 cards, some times I'll get 30 on the first two cards, then it'll drop down to 17
Any insight would be really appreciated
The fluctuating is I would say normal when you overclock you cards, I see you have +700 temperature and +175 core clock. If most of the time is staying on 30 mhash and just some times it goes down to 17-16 mhash I would say this is normal. It happens to my GTX-s 1060 too, I have overclocked them +65 core clock and +750 memory, power limit 73%. They are stable most of the time but sometime the hash rate in ethereum goes from 22.2 mhash to 14 mhash for a few minutes then back up as they should.
