Then log out and log back in and all the GPUs will have overclocking and fan control enabled. Log out and then log back in, then enable overclocking on all the other identical GPUs: Problems setting nvidia-xconfig for multi-GPU rigs try this work-around-įirstly, log in and enable overclocking on one GPU: sh to the programs you run when you log in. Save and open properties and make each file 'executable'.

Make separate documents for each GPU by changing the numbers for each card. Nvidia-settings -a '/GPUTargetFanSpeed=80'Īmend the clocks (GPU and Memory) and fan speeds to whatever you're comfortable with. Nvidia-settings -a '/GPUFanControlState=1' Nvidia-settings -a '/GPUMemoryTransferRateOffset=100' Nvidia-settings -a '/GPUGraphicsMemoryOffset=100'

To finish, you will create a startup sh file for each GPU so the overclocks and fan speed are loaded when you log into Ubuntu 16.04LTS.Ĭreate some empty documents on Ubuntu Desktop and call them whatever you like.
