I have 1 GTX1060 with 6GB and 4 GTX1060 with 3GB. They are all clocked at 1711 MHz core and +700 MHz memory, so the performance shpuöd be similar. The 6GB is set to 32 threads and 30 blocks, the 3GB cards at 32 threads and 27 blocks (as only 9 SMX).\r\n\r\nResults with XMR-Stak:\r\n0: 426  /  1: 529  /  2: 495  /  3: 400  /  4: 440    --> 2290 H/s\r\n\r\nResults with XMR-Stak-NVIDIA:\r\n0: 534  /  1: 526  /  2: 529  /  3: 531  /  4: 531    --> 2652 H/s\r\n\r\nThat's almost 14% more with the NVIDIA version of the miner. It's also strange that the cards yield so different in XMR-Stak. Any idea from dev site?\r\n\r\nBest regards\r\n\r\nStefan"},"comment":{"url":"https://api.github.com/repos/fireice-uk/xmr-stak/issues/comments/382724736","html_url":"https://github.com/fireice-uk/xmr-stak/issues/748#issuecomment-382724736","issue_url":"https://api.github.com/repos/fireice-uk/xmr-stak/issues/748","id":382724736,"user":{"login":"stna1981","id":29736665,"avatar_url":"https://avatars2.githubusercontent.com/u/29736665?v=4","gravatar_id":"","url":"https://api.github.com/users/stna1981","html_url":"https://github.com/stna1981","followers_url":"https://api.github.com/users/stna1981/followers","following_url":"https://api.github.com/users/stna1981/following{/other_user}","gists_url":"https://api.github.com/users/stna1981/gists{/gist_id}","starred_url":"https://api.github.com/users/stna1981/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/stna1981/subscriptions","organizations_url":"https://api.github.com/users/stna1981/orgs","repos_url":"https://api.github.com/users/stna1981/repos","events_url":"https://api.github.com/users/stna1981/events{/privacy}","received_events_url":"https://api.github.com/users/stna1981/received_events","type":"User","site_admin":false},"created_at":"2018-04-19T12:58:43Z","updated_at":"2018-04-19T12:58:43Z","author_association":"NONE","body":"I made a new comparison with 8x GTX 1060 3GB, all running at 1709/4600, with driver 391.35.\r\n\r\n**XMRStak-NVIDIA:**\r\n| ID |  10s |  60s |  15m | ID |  10s |  60s |  15m |\r\n|  0 | 540.7 | 540.4 | 540.6 |  1 | 540.7 | 540.8 | 541.4 |\r\n|  2 | 540.8 | 540.6 | 540.7 |  3 | 541.8 | 541.6 | 542.0 |\r\n|  4 | 542.4 | 542.0 | 542.4 |  5 | 542.0 | 541.8 | 542.0 |\r\n|  6 | 540.5 | 540.0 | 540.5 |  7 | 541.1 | 541.7 | 541.9 |\r\nTotals:   4330.1 4328.8 4331.4 H/s\r\n\r\nAs you can see the hashrate is between 540.5 and 542.4, i. e. more or less identical.\r\n\r\n**XMR-Stak 2.4.1:**\r\n| ID |    10s |    60s |    15m | ID |    10s |    60s |    15m |\r\n|  0 |  541.2 |  541.1 |  541.0 |  1 |  534.3 |  533.5 |  534.5 |\r\n|  2 |  536.9 |  536.8 |  534.9 |  3 |  525.4 |  523.3 |  522.3 |\r\n|  4 |  523.0 |  523.5 |  521.0 |  5 |  522.2 |  519.9 |  520.6 |\r\n|  6 |  519.3 |  519.1 |  518.5 |  7 |  538.8 |  538.3 |  537.9 |\r\nTotals (NVIDIA):  4241.0 4235.6 4230.6 H/s\r\n\r\nHere the hashrate is between 519.3 and 541.2, i.e. a variace of 22 H/s or about 4%.\r\nStill don't understand how the driver can be the reason if it performs nice with the older version..."}}
