This will probably need to be executed at boot. Fan speed configurationĬreate a script (named gpufansetting in this example) in your user home or somewhere convenient. Above command creates sections for each GPU in the system. If you want to set all cool-bits binary bits to ‘1’ to control other aspects of the GPU, you can just set –cool-bits=31. sudo nvidia-xconfig -enable-all-gpus -allow-empty-initial-configuration -cool-bits=7 Without the “cool-bits” option set to a proper value in the nf file, trying to set fan speeds will just not work. You can check any existing configuration file /etc/X11/nf for the coolbits setting, or just create a new one using the command below. Make the script run on boot Install and Configure Xorgįirst we need to have Xorg installed and configured properly. Install Xorg and create nf configuration file Our post on Mining Pods using CentOS 7.4 with CUDA 9.1, covers the procedure for CentOS, and was tested with NVIDA FE GPU cards and some Zotac cards. The procedure was tested on Ubuntu 16.04.2 LTS with EVGA GTX 1050 Ti GPUs, on Ubuntu 16.04.3 LTS with EVGA and ASUS GTX 10 Ti GPUs. Unfortunately it appears that we cannot avoid installing and keeping running an Xorg server, just to change GPU settings and keep them that way. The following steps are needed to make this permanent, and without any display attached (a headless system.) This generally applies to datacenter and remote server environments.Ī simple search on the the Internet was not sufficient to make things work so here is a write-up that works. The following assumes you installed Ubuntu Server without desktop environment, you do not want to run a desktop manager, and you need a command prompt after reboot. In high-performance computing applications when the system is in a datacenter, it is often preferable to run the fan at maximum speeds for lowest possible operating temperature to possibly prolong the life of the hardware. NVIDIA GPUs have fan speed profiles that control the fan to keep the noise to a minimum.
