    TDP and turbo parameter modification with MSR on non-overclockable CPU

Disclaimer


MSR modification may void your CPU's (or system board's) warranty. Proceed with care. I'm not responsible for any destruction caused by this article.
MSR address (greatly) differs from CPU to CPU. Check your own CPU's MSR address using Intel's documentation.
Only tested on Intel i7-8550U (Kaby Lake R).
This article is translation of this article. If you can understand Korean, I recommend reading that article, not this.
