There are some new processors to be released soon, Ryzen 3 3100 and 3300X, likely they'll need a firmware update as all of the sudden a handful of X570 motherboards show a BIOS update, with firmware revision 1.0.0.5.

MSI seems to be the first to drop the new BIOS update AGESA 1.0.0.5. ComboAM4 1.0.0.5 is currently only available from MSI for the following models:

B450M-A Pro MAX

B450M Pro-VDH MAX

B450M Pro-M2 MAX

B450M Mortar MAX

B450-A Pro MAX

B450 Tomahawk MAX

B450 Gaming Plus MAX



An unofficial and thus beta test BIOS is available for the MEG X570 Ace and MEG X570 Godlike reports Hardwareluxx. From the looks of things, MSI testing its B450 mainboards before extending the update to other models. The changes list is minimal though:

Updated AMD AGESA ComboAm4PI 1.0.0.5

Fix HDMI audio lost issue when use AMD RX570 vga card.
