Go to solution Solved by The_russian,

I believe Validated since PCB means that the CPU has been validated to work since the motherboard has existed, basically on the original BIOS version. Validated since BIOS means that the CPU has been validated to work after updating to a new BIOS version.

Recently I was looking at a mobo ROG strix X570 E gaming  on ASUS offical website .

In that ASUS CPU support , there was a column named "validated since PCB" and in this column all entries were "ALL"

Validated since pcb (and this is my assumption ) Im pretty sure it means that is it compatible with the cpu (all of zen products in this case ) out of the box 

And validated since since bios I would assume means it is also compatible but after the bios update 

PC: Motherboard: ASUS B550M TUF-Plus, CPU: Ryzen 3 3100, CPU Cooler: Arctic Freezer 34, GPU: GIGABYTE WindForce GTX1650S, RAM: HyperX Fury RGB 2x8GB 3200 CL16, Case, CoolerMaster MB311L ARGB, Boot Drive: 250GB MX500, Game Drive: WD Blue 1TB 7200RPM HDD.

That ALL PCB revisions support it (in case there are more than one)

Sometimes there are different hardware revisions of the "same" board.

I think Kilrah is correct, it probably means that all versions of a motherboard support that CPU. On some, or all I'm not sure, motherboards there is a version number, usually v1.0. If the manufacturer needs to change something about the motherboard, they will make a new version, like v1.1 or v2.0 or something similar.
