GUI app to show at real time RAM being used and with its frequency (MHz) too

Hello Friends

Do you know a GUI app where it shows the total and current RAM being used?
Until here the already installed System Monitor app (at GNOME) does the job

But is need it show at real time the frequency (MHz) too. Is it possible?

Just in case as an alternative in the terminal world the htop and btop apps do not show the frequency (MHz). I know the dmidecode command can show data of the RAM but it is static, is need it at real time.

Thanks in advance

I use a Flatpak install of Mission Center. That shows lots of info including the CPU frequency and RAM usage.

I always have my conky running.

Huge thanks to both for the recommendations :clinking_beer_mugs:

Soon as I can I am going to test them (same as the apps for terminal for git branches history)

Thanks to all!!!
