How can I change Default Application Clocks on a GeForce 840M using nvidia-smi or something else. I can set the application clocks using nvidia-smi -ac 405,405. Here is nvidia-smi -q
Applications Clocks
Graphics : 405 MHz
Memory : 405 MHz
Default Applications Clocks
Graphics : 1029 MHz
Memory : 800 MHz
Max Clocks
Graphics : 980 MHz
SM : 980 MHz
Memory : 800 MHz
Video : 960 MHz
I would like to underclock the GPU to get a quieter laptop while still using it for compute tasks, and would appreciate information on how to do more. I am setting max clocks using:
nvidia-settings -a GpuGraphicsClockOffset[2]=-135
nvidia-settings -a GPUMemoryTransferRateOffset[2]=-320
I have application profiles setup, but I’m not sure what clocks the applications are running under. Are the application settings effective only for overclocking? Can I underclock the GPU any more than what Max Clocks shows?
