Sup guys. I’ve been recently playing with different bios versions on my B550M Mortar board with 5600x. I found that beta bios from december 2020 (deleted from msi site) allows you to run PBO up to +500 (5150mhz!) but unfortunately this version of bios gives WHEAS every 2 hours even when PBO disabled.
The latest and most stable in terms of OC version of bios allows only +200 pbo, could anyone please unlock PBO and disable HPET? This board are pretty popular in Russia.

Beta bios with +500 pbo as example :

Stable best bios which need to be modified :

If this board has any hidden features i would be pleased to see them unlocked.
I have time to wait and could do any dump if needed. Just tell which software i have to use.

Made some screenshots of 154 beta and 1D0 bioses.
