I don’t trust 2 year old articles too much … Anyway my exact situation. I have the plans, I used them for my 3800X before upgrading to the 5800X but they dissappeard when I updated and/or reinstalled every driver for MB, chipset and cpu. Six months later AMD posted a new chipset driver, I installed it and then noticed the plans have returned. The only thing unchanged is my Windows 11 install but I keep that updated anyway.
Anyway you may be right or half right especially as PBO is controlling my voltages but stuff like keeping usb keyboard, drives etc. alert and ready are all part of the plans too.
