Try and force Linux Nvidia cards to higher Performance Level , ie. pstate ie perflevel #456

twiggy · 2017-12-21T22:23:00Z

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.

Profetul · 2018-01-10T12:39:16Z

@bm2k Ubuntu nVidia drivers come with an utility named nvidia-settings -
Running sudo nvidia-xconfig --cool-bits=28 should enable you to change the OC settings of the card

A quick search on google yielded this result ... https://gist.github.com/bsodmike/369f8a202c5a5c97cfbd481264d549e9

Try Update Drivers.
Download and install the latests.
Try use -U for CUDA devices.
That's my launch command:
ethminer.exe -RH -U -S eu1.ethermine.org:4444 -FS us1.ethermine.org:4444 -O 0x7013275311fc37ccc1e40193D75086293eCb43A4.test
Try to change P2 State and Power managment mode.
You can use NVidiaProfileInspectorDmW.
For the best mining hashrate choose from sector "5 - Common":
- CUDA - Force P2 State (Set to "Off")
- Power managment mode (Set to "Prefer maximum performance")
Try Tweak Win10.
You can use Windows10MiningTweaksDmW (Solution for 100% CPU usage (Win10 - CUDA - OpenCL) #695).
Try Optimize/Overclock GPUs.
You can use MSI Afterburner for GPU OverClock/Optimize.
My settings +150/+500/65%TDP
Hashrate 31-32@52oC
Try use a WatchDog
You can use ETHminerWatchDogDmW (Simple Script WatchDog #735).

Please feedback.
Thank you!

@DeadManWalkingTO please, give us the linux version of your answer

Linux

Try Update Drivers.
Download and install the latests.
Try Update Ethminer.
Download (or beter build) the latest.
Try use -U for CUDA devices.
CUDA Hardware Test Launch Command:

./ethminer -RH -U -S eu1.ethermine.org:4444 -FS us1.ethermine.org:4444 -O 0x7013275311fc37ccc1e40193D75086293eCb43A4.hardwaretest

Try to change P2 State and Power managment mode.
You can use nvidia-smi.

My actual clock is in +1000 for mem and -200 for core.

more than 1000 system gets little buggy.

step 4. changes nothing.
I kept on shit 18.5Mh/s.

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

DeadManWalkingTO · 2018-03-05T20:42:43Z

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.
Thank you!
