Hi
I would like to know if I can change some hardware settings of my RTX 3080 via nvidia-smi command line tool. As a first try and based on the documents available on the web, I did the following steps:
$ nvidia-smi

$ sudo nvidia-smi -i 0 -pm 1
Enabled persistence mode for GPU 00000000:2D:00.0.
All done.
$ nvidia-smi -i 0 --query-supported-clocks=mem,gr --format=csv
memory [MHz], graphics [MHz]
9501 MHz, 2130 MHz
9501 MHz, 2115 MHz
...
$ sudo nvidia-smi -i 0 -ac 9501,2130
Setting applications clocks is not supported for GPU 00000000:2D:00.0.
Treating as warning and moving on.
All done.
So, it seems that the device doesn’t support such modifications. I would like to know if that is all or I have to do some more things. Any comments on that?
