How see current voltage and frequency?

Ubuntu 20.04.6 GT 640 driver 470.
In windows is possible using EVGA Precision X see video card current voltage and frequency.
In Linux Is possible see current voltage ?
Have an software similar as Precision X for Linux ?

Have an nice week.

I don’t think voltage display is supported on low-end kepler cards. Clocks can mostly only displayed by nvidia-settings

yeah … you are correct.
I remember being possible change voltage values using Precision X.

Yes, possible. I meant to say “not supported” on linux.
