fan speed error #1

Open FlorinAndrei opened 6 years ago

FlorinAndrei commented 6 years ago

Running this command:

POWER=65 nvidia-control.sh

I get this error repeated over and over:

ERROR: Error assigning value 93 to attribute 'GPUTargetFanSpeed'
       (media:0[fan:0]) as specified in assignment
       '[fan:0]/GPUTargetFanSpeed=93' (Unknown Error).

Ubuntu 16.04

Titan X Pascal

driver version 370.28

EDIT: The custom power value is assigned just fine, by the way.

Hi @FlorinAndrei , sorry for the late reply, I think this error happens if you don't have the right "coolbits" applied to the GPU.

If you search for "coolbits", you get a description of the various values you can use, 4 is the minimum for fan speed control.

You can also combine multiple bits to enable multiple features, the arch wiki has some info on this: https://wiki.archlinux.org/index.php/NVIDIA/Tips_and_tricks#Enabling_overclocking

You can set this at runtime like this (first line applies if you have more than 1 gpu):


nvidia-xconfig --enable-all-gpus
nvidia-xconfig --cool-bits=4
