Hey, I also have 1401 installed, and my L3 cache speed on 5600X is extremely slow !

Why I can't find any info regarding removal of this bios anywhere?
I would also address an issue with the fans control !!!!!!
The step up and step down doesn't work AT ALL.
The motherboard would just ignore the setting regarding the fan step up and step down adjustments.
The fan would just ramp up and slow down instantly, without taking in consideration the time set to spin up.
The same fans worked flawlessly on the B450 Strix board, and the issues I am having started right after board upgrade to B550 Strix.
