I have now added 2 GTX1060 GPUs to my rig that previously had only one GTX1080.
Hash rates look reasonable but I noticed that both of the GTX1060s were running below their expected power numbers, ~62W vs. 75W.
The GTX1080 is still running around 200W as before I added these two and that is expected.
So I monitored the "screen -r temp" printout for a while and noticed this:
ERROR: Error assigning value 75 to attribute 'GPUTargetFanSpeed' (m1-desktop:0[fan:2]) as
specified in assignment '[fan:2]/GPUTargetFanSpeed=75' (Unknown Error).
I see a similar message that mentions the other GTX1060.
Is this problem occurring possibly because I have mixed GPUs now?
Do I need to set individual OC/power numbers?
Thanks for the help.
I have made some progress clearing up this ERROR and it has to do with the NVIDIA driver not recognizing a card as having a "SCREEN" setup inetc/X11/xorg.conf
When I run this command:
sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration
After a reboot, I get full control of all parameters on all cards installed including the individual power, temp and clocks which is why the 1060s I added previously were not going to full requested power.
This holds true until I change something in the system that causes the XORG to balk on reboot, at which time it resorts back to the same error again.
I run the command above again and all is well.
For some reason, some system changes cause a reset of all the parameters in xorg.conf back to default values.
I can't explain it but through trial and error I am able to work around it.
