Seems to be similar to the laptop AC adapter protocol but has some weird differences I’ve been trying to figure out. I hate stupid genuine checks that are actually pointless and limit hardware performance. All this so I can use a usb-c to 4.5mm adapter instead of the giant dell adapter. Otherwise I’m limited to 800mhz.
I bypassed this very easily by disabling turbo-boost and virtualization in the BIOS. Not sure which setting did the trick but no software was needed after this to run at 2.0 Ghz powered by a 20v USB C adapter. To go above 2.0, I used ThrottleStop.
This would be an option but I need virtualization support to run Proxmox with VMs. Thanks for the info though, I'll keep it in mind!
The fix I described before stopped working/ only works intermittently. However, installing Tiny10 on it somehow lets it run at full speed out of the box with no obvious BIOS setting or Throttlestop needed.

It looks like you might be able to use grub2 to boot in windows, and use this method above to remove the throttle before the windows boot loader starts up. I’ve tested it with my Lubuntu install and it works using the grub method but using wrmsr from the command line after boot does not work.
