Description:
All utilities in Linux report CPU frequencies for this CPU that is outside of the range that this CPU is capable of.

As an example, here is the output of lscpu:

There is a little more information on the CPU here:

I have a thread open with Intel themselves, but they don't seem too interested in what I am seeing:
https://community.intel.com/t5/Processors/Wildly-different-clock-speeds-reported-in-Windows-vs-Linux-for/m-p/1529153#M9023

If you require any more information from me, or have things that you would like me to test, I promise to be really responsive.
Because I can't see the proper CPU frequencies, I don't know whether this CPU is turbo boosting or not, and I don't even know if it is properly being utilized.
