Let me begin by joining the chorus of miners praising this effort. I spent a week working towards the same goal before finding this thread. I think you've probably saved me a month of evenings developing something similar. Sending some hashes your way as I test!
I'm using an msi z170a m5 with 4 Asus GTX 1060 6G GPUs on an 850w PSU. I'm also running a single gtx 1060 on a muuuuch older board Asus p5n-d (yes that old) and nvOC still works like a charm.
One thing I've noticed with nvOC versus my own Linux install is that I can't seem to get the same hashrate in nvOC. Even if I set the pl to 140 for the card, push memory all the way to 2000 and the GPU clock offset to 130, I can't break 21 MHS in nvOC. Comparatively, if I just load Ubuntu 16.04 with xorg, gnome and latest drivers with Claymore dual mining ETH and SC, I can sustain 23 MHS for days. Same if I put a card on my Win10 box and use MSI Afterburner to contro OC there. I've tried throwing configurations at my nvOC node manually with nvidia-settings -a and it just doesn't seem to get beyond 20 MHS. I can open the nvidia control panel and verify all the settings took. The only difference I can find so far between nvOC and my own build is that I was still using 375.66 version of the driver and nvOC appears to be using 378.13.
Anyone have any thoughts or suggestion of what else I could try? I'd love to switch all my gear to this but right now I'm getting better hash rates out of a 1060 in win10 and 1060s on Ubuntu not using nvOC. And across multiple 8 GPU rigs, the delta adds up.
Thanks!
From most data sets you will get slighly better hashrate from Windows still, even some 1070's I have seen pushing 31-33 while on Ubuntu I have only gotten 29-31. The biggest advantage though I will say is stability, Ubuntu has shown more constant and stable hashrate by far then any Windows PC (this is beyond the Win 10 auto update on home edition)
When mining Ethash going nuts with power is not the answer. Most of the time it will result with a perhaps marginally better hashrate, but significant instability.
I would recommend trying:
-100cc
+1100mc
powerlimit 110
higher mc might do better with your specific cards; I don't have any ASUS 1060s so I don't have a reference.
I would start with those settings and bump up the mc every 5 mins or so and test the results.
Some cards do better with different drivers. I choose the 378 driver based mainly on testing 1070s (as they are the best $/hash GPUs when normally priced / available) and it also fully supports 1080tis.
I have already had another member request a 375 driver version; for maxwell cards (it is opt for them) so eventually I will make a build with it as well.
Nexillus is correct in that it is usually possible to get sightly higher hashrates in Windows; although I always had to use the OC after building the DAG trick to do this: but in general I believe it is because Claymore spends more time Optimizing for windows. (we need to change this)
