TDP and turbo parameter modification with MSR on non-overclockable Intel CPU (such as Intel i7-8550U)

TDP and Turbo Parameter Modification with MSR on Non-Overclockable CPUs

Disclaimer

  • Modifying MSR may void your CPU's (or system board's) warranty. Proceed with caution. I am not responsible for any damage caused by this article.
  • MSR addresses vary significantly between CPUs. Check your CPU's MSR address using Intel's documentation.
  • This has only been tested on the Intel i7-8550U (Kaby Lake R).
  • This article is a translation of this article. If you can read Korean, I recommend reading that article instead.
