Cheap and cheerful motherboard, very basic but functional.Box said Ryzen 5000 compatible, but did not work with a Ryzen 5 5600G.Only compatible BIOS is a beta BIOS.Therefore I swapped CPU's with another system I have. The 5600G fitted straight in to my Asus board as a compatible BIOS has been out a while.MSI need to be quicker with their BIOS updates.
