Starting with the B550 chipset, AMD restarts the version number of AGESA

AGESA is part of the AMD platform BIOS, provided by AMD, to initialize the platform. It includes not only the initialization processor-related code, but also the code like Intel Microcode, and every time you update AGESA, AMD fixes some bugs and may improve cpu stability and may bring some performance changes.

For each generation of Ryzen processor, AGESA has a branch version, in the Zen 2 processor launch, AGESA forked out the new ComboAM4 version, the current branch has been updated to 1.0.0.5, many motherboard factories have now launched the VERSION of AGESA BIOS update, and for the B550 motherboard has been launched, will be released next month, we expect it will directly integrate the latest version of A, But now it looks as if AMD is going to fork out a new version.

Starting with the B550 chipset, AMD restarts the version number of AGESA

According to HardwareLuxx, someone in their forum gave a screenshot of the B550 motherboard BIOS version number, the name of comboAM4 v2 appeared, and its version number did not follow the current ComboAM4 1.0.0.5, but jumped back to 1.0.0.0. Even the B550 motherboard, which has not yet been officially released, has had a poor version of the AGESA, with a MAG B550 Tomahawk using ComboAM4 v2 1.0.0.0,and a TechNocinthine B550 AORUS MASTER using 1.0.0.1.

It is not yet known why AMD is launching a new v2 version and resetting the version number, nor is it whether it will be a separate special version of AGESA for b550, X570 will not be updated to v2 version in the future, these questions are subject to the official answer sat in the future for us. In short, the introduction of v2 version of AGESA will make consumers feel a certain confusion, but ordinary consumers also have to follow the motherboard manufacturers on the line, there is no need to care about so many things.
