Need help with CPU speed readout(script)

Hey,

I'm currently working on a script in Powershell to automatically check some system specs and confirm if they are correct or not. Some of the interns here are having difficulties with this, so I thought, why not help them by doing the check via script.

One thing I haven't found a solution to, is getting the correct CPU speed.

WMI and DMIdecode didn't give me the right speed. DMIdecode worked a little better though.

When overclocked, it always shows the wrong value.

Since I'm not very deep into scripting or building programs, I was wondering if anyone could give me some tips on how to read out the correct speed via a script. I guess it has to be via something that reads out from the BIOS, and maybe a calculation from MP and bClk.

Thanks in advance,
