Last week, we saw the first public rollout of AMD's latest AGESA 1.0.0.5 microcode for AM4 boards which adds improved compatibility and support for Ryzen based systems. The AGESA 1.0.0.5 was delivered by MSI first on its MAX series (A320, B450, X470) motherboards but now, MSI is rolling out the BIOS update for its entire X570 lineup including a few new additions.

As expected, the AMD AGESA 1.0.0.5 BIOS firmware BIOS landing on MSI's X570 motherboards is a BETA version while the 300/400 series motherboards are releasing a final version BIOS. MSI will be releasing the BETA BIOS for 9 X570 motherboards, which is in addition to the 13 X470, B450 & A320 motherboards that have already received it.
