First, thank you so much fullzero  Grin for this.  I've rolled my own in the past, so this was a nice find and saved me a lot of trouble to do my own.

Have a couple of questions
1) I'm using 4 x PNY GTX 1060 3GB cards on a Gigabyte Z97 SOC Force motherboard.  Under Win10 with power 70, cclock 150, and mclock 850 I consistently get ~23 Mh/s.  With nvOC with the same settings I get 21.4 Mh/s.  Increasing the mclock doesn't seem to increase the hashrate.  cclock at 100 doesn't seem to make a difference either.

My oneBash looks like this:
Code:
COIN="ETH"

POWERLIMIT="70"                 # YES NO

INDIVIDUAL_POWERLIMIT="NO"      # YES NO

__CORE_OVERCLOCK=150
MEMORY_OVERCLOCK=850

INDIVIDUAL_CLOCKS="NO"          # YES NO

When the bash file starts it shows that the attributes are set, but it appears that the clock settings aren't taking effect. I don't see any errors thrown when Claymore starts up except that the cuda library doesn't have a version number.

2) I added a couple of parameters to the Eth command line, but it doesn't seem to pick them up.  For instance, when try to interactively change the dcri it tells me that i need to set -asm 1, but that is already set in the bash file.
Code:
if [ $COIN == "ETH" ]
then
HCD='/home/m1/9.0/ethdcrminer64'
ETHADDR="$ETH_ADDRESS/$ETH_WORKER"

if [ $ETHERMINEdotORG == "YES" ]
then
ETHADDR="$ETH_ADDRESS.$ETH_WORKER"
fi

until $HCD -epool $ETH_POOL -ewal $ETHADDR -epsw x -mode 1 -esm 0 -estale 0 -asm 1 -dcri 12
   do
   echo "FAILURE; reinit in 5" >&2
   sleep 5
done
fi

Any recommendations would be much appreciated.  Windows 10 sucks for mining - so much babysitting, so hoping to get this tweaked and running well.


Powerlimits in windows are in percent TDP; in linux they are in watts.  Thus a powerlimit of 70 in windows is .7 * 120 watts or whatever the TDP is (84 watts if the card TDP is 120); while 70 in linux is 70 watts.  I would recommend comparing Windows and linux powerlimits with a kill-a-watt to get them exactly equal; but most likely a 3gb 1060 has a 120 or 125 watt TDP.

Also linux OC offsets are scaled differently than windows; you will need to use higher offsets to get the same results in linux.

In regards to Claymore ETH settings; the Claymore readme says -asm is for AMD only.  I haven't tested this but -dcri 30 (or any valid number) is only supposed to work with mode 1 (ETH only) if -asm mode is used.



fullzero, thank you for the quick reply.  This was hugely helpful.

So strange that Windows is percentage of TDP and linux is watts.  The PNY 1060-3's are 120W TDP, so I've set it at 84 in linux.  I'll check it out with my power meter.

I increased the mclock to 1500, which is getting me about 22.7 Mh/s now.  I'll keep playing with it, but I see that the nvidia control panel has a max of 2000 for memory, whereas it's 1000 in afterburner on Windows.  It seems like the offset might be 2:1 on linux, so my 850 would be 1700 on linux.

Finally, with the dcri, you're right.  I have a mix of AMD and nvidia cards, so just assumed it worked on nvidia.  Tried it on a Windows nvidia only rig, and it gives the same error, so pretty sure dcri tuning doesn't work with nvidia cards.

Thanks again, this rocks!
