Is there a way to monitor the current CPU core voltage and overclock, similarly to CPU-Z but for the raspberry pi? This is so I can check that nothing is limiting the overvolt or overclock.

These commands should do it. 

vcgencmd measure_clock arm
vcgencmd measure_volts core

If you like to monitor them in realtime, you can use watch:

watch -n1 "vcgencmd measure_clock arm && vcgencmd measure_volts core

or you can add a cronjob to write it inside file.

Is that what you are looking for?

  • Does this show what the overclock/overvolt is meant to be, or what it currently is?

  • It shows what there currently is. You can try that by workloading your CPU. For that you can use stress . It's availible for Archlinux ARM even for Raspbian in official repositories.
