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.

Introduction

#!/usr/bin/awk -f
# This program is a copy of guff, a plot device. https://github.com/silentbicycle/guff
# My copy here is written in awk instead of C, has no compelling benefit.
# Public domain. @thingskatedid
# Run as awk -v x=xyz ... or env variables for stuff?
# Assumptions: the data is evenly spaced along the x-axis
# TODO: moving average
