Dear developers. Do you know why every month the ETH hashrate decreases a bit on 1070-1080Ti video cards? About 2-3 MX per year. On AMD cards and on 1066 - this does not happen, everything is ok there. Thank you in advance!
I also wants to know answer this question. In the first half of this year my 6 1070 have 192Mh. Now they have 183.8Mh. Moreover I decreased MC, because with MC I used before, hashrate is even less. But there is nothing incorrect shares, so looks like hardware works good.
May be it will help you.
I had some experiments.
1. Used Claymore 15.0. Still slower then PM. PM now have 184.2-184.5. So back to PM.
I had the following settings:
PM: 4.7c
CV: +0
PL: 64
CC: +0
MC:
1: +540 - 31.01
2: +540 - 30.94
3: +450 - 30.33
4: +510 - 30.79
5: +540 - 30.95
6: +450 - 30.39
-------
184.41 (PM shows 635W)
Each MC was setted up for each card.
Remember? I told that a half year ago I had 192Mh with MC +640 for all cards!
2. Changed PL. After increasing PL from 64 hashrate became growing.
With PL 100 and MC +650 for all cards I have now 192.5Mh (PM shows 905W power).
With PL 80 and MC +650: 192.4Mh (792-803W).
With PL 70 and MC +650: 191.5Mh (696-701W).
With PL 69 and MC +650: 190.6Mh (685-690W).
With PL 68 and MC +650: 189.4Mh (672W).
With PL 67 and MC +650: 187.9Mh (668W).
With PL 66 and MC +650: 186.1Mh (660W).
With PL 65 and MC +650: 184.2Mh (644W).
With PL 64 and MC +650: 182.5Mh (636W).
So after 2.5 years of mining my optimal working PL became 70, but was 64.
