… Nvidia has been a bunch of a bad boys and has been nerfing the linux
drivers ability to set clock rates and such.
As soon as ethminer kicks in some 1060 and 1070 cards will change from
Performance Level 3 to Performance Level 2. This results in a bit of a drop
in MHS.
Is there anyway the ethminer could trick these cards into needing a higher
level.

Unfortunately -ac would not work on 1070 cards - what I've done to mine is set the memory OC to a value that would match P2 to the value I would normally get in P3. My Gigabyte GTX 1070 G1 reports 30 Mh/s having the memory OC to 8808 MHz instead of the standard 8008 MHz and runs at 61C with power limit set to 120W. (To get there I have to OC Memory +1200! -> P2 would show 8808) Default settings on 1070 would get me 26 Mh/s - so with minor adjustments the hash-rate can be improved with about 15% and with less power usage. I can confirm that -ac works for my 970 card, but I don't notice any hash rate improvements - might be because of having the power limit set to 100W. I get ~9.5 Mh/s so it's a waste of power compared to 1070. This guy has some nice scripts to make ethminer a daemon on Linux - https://gist.github.com/bmatthewshea I've just added in his ethminer-monitor.sh some lines to set the power limits using nvidia-smi and to set OC using nvidia-settings - this way if my computer restarts it would always have the correct settings. |
@Profetul Good information. I also have GeForce 1070 cards and Linux your answer is relevant for me. The one key piece of info you left out is how exactly do you overclock in Linux w/out using the "-ac" setting? What commands do you use? I know in Windows people use tools like MSI Afterburner and such, but for Linux I have not come across any OC'ing tools. My 1070's also get ~26MH/s out of the box. |
@bm2k Ubuntu nVidia drivers come with an utility named nvidia-settings - A quick search on google yielded this result ... https://gist.github.com/bsodmike/369f8a202c5a5c97cfbd481264d549e9 |
Please feedback. |
@DeadManWalkingTO please, give us the linux version of your answer |

Please feedback. |
What does WatchDog do? i don't know what it is/how use it... `nvidia-smi -q -d PERFORMANCE ==============NVSMI LOG============== Timestamp : Sun Mar 4 17:46:07 2018 Attached GPUs : 1 ==============NVSMI LOG============== Timestamp : Sun Mar 4 17:45:49 2018 Attached GPUs : 1 ert@romario-computer:~$ nvidia-smi -q -d PERFORMANCE ==============NVSMI LOG============== Timestamp : Sun Mar 4 17:45:06 2018 Attached GPUs : 1 more than 1000 system gets little buggy. step 4. changes nothing. really, this GPU should work on 25Mh/s. This is a 30% loss!!! Many people with Hynix memory are with this problem, this has to be a solution |
After #757 (added --exit parameter to exit whenever an error occurred) you can use a watchdog. Try ETHminerWatchDogDmW Windows7/8/10 [32/64] & Linux (Any Dist/Any Ver/Any Arch) (#735). Check and feedback please. |
How do i use ETHminerwatchDogDmw??? |
