After having updated my headless gpu server (4 GTX 1080Ti) to the latest nvidia drivers v440.44, the performance mode of my 4 GPUs when not used is stuck to P0. I do not have any X11 folder (headless server) and I tried the following options into a new /etc/modprobe.d/nvidia.conf file (i ve created)
options nvidia NVreg_RegistryDwords=“PowerMizerEnable=0x1”
options nvidia NVreg_DynamicPowerManagement=0x02
and i applied these changes by doing this
sudo modprobe -r nvidia_drm nvidia_modeset nvidia
sudo modprobe nvidia_drm nvidia_modeset nvidia
But still the same pb. Any idea ?
