Forcing Higher TDP and All Core Max Turbo With MSR TOOLS
by finalturismo from LinuxQuestions.org on (#5SQ88)
So i have been doing a bit of reading and found out you can force your intel based cpu to its max turbo ratio across all cores
and by pass the tdp limit using wrmsr from the msr-tools package.
Problem is there are like zero guides for doing this and i was wondering if one of you guys could me understand this.
Here is a link for basic explanation.

Here is the link for the cpu specific msr links from intel.

I installed the msr-tools package and enabled a kernel parameter for it and it seems be working. I was able to write msrs to my cpu, but the best ive goten was instability till crash or lower clock speeds.
The most i understand is how to choose to msr registry attribute to change, but i dont understand how to generate the mask for my cpu cores and their multiple values.
Anyway this a very rare find and it allows you to get non unlocked cpus to their max turbo values on all cores. So maybe one of you can help me for finding this XD.
Heres a link with a good break down of msr calculation, but i still dont get it...
