Welcome to the index page of my knowledge base, if you haven't done so, do visit my website at https://jarylchng.com.

I will mainly use this site to document stuff, most of which will likely be in the public domain.

Steps

Firstly we will have to one-time initialize /etc/X11/xorg.conf by using Nvidia's xconfig tool including a cool-bits value of 28.

nvidia-xconfig --allow-empty-initial-configuration --enable-all-gpus --cool-bits=28\n

Afterwards, we can start a Xorg server headlessly as Nvidia's setting tool requires it to be up.

X :0 & # display :0\n

Since I am running multiple cards, I would require a loop to go through all of it. Currently these values works best for the cards I used.

# export DISPLAY=:0\n# IFS=$'\\n'\n# for gpu in $(nvidia-smi -L); do\n    id=$(echo ${gpu} | sed -e 's/GPU //g' -e 's/:.*//g')\n    nvidia-settings -a [gpu:${id}]/GPUPowerMizerMode=1 -a [gpu:${id}]/GPUGraphicsClockOffset[3]=-200 -a [gpu:${id}]/GPUMemoryTransferRateOffset[3]=1200\ndone\n

As a final step, I would apply a -40 max watts undervolt as root.

nvidia-smi -pl 140\n

Optionally, since we do not need the Xorg server to be running anymore, we can kill it

killall Xorg\n

These configuration alone increased ~5MH/s per card, resulting in a 25-30MH/s overall increase!
