AMD 300 series motherboards are the first AM4 platforms, and they arrived with the first-generation Ryzen processors. By this year, they have been on the market for 5 years. In fact, AMD is also very swaying about whether to let these motherboards support the latest Ryzen 5000 series processors. At first, AMD was firmly opposed, but from time to time, the board factory will throw out a BIOS that allows AMD 300 series motherboards to support Ryzen 5000 series processors. At the beginning of this year, AMD relented, saying that they were working on how to make 300 series motherboards support Ryzen 5000 series (Vermeer) processors.
AMD has now announced that they will provide official Ryzen 5000 series processor support for the oldest AM4 motherboards. These motherboards include the X370, B350, and A320, and they are working with board makers and OEMs to push new firmware updates.
In addition to the Ryzen 5000 series processors with Zen 3 architecture, AMD will also fully add support for the Zen 2 architecture processors of the Ryzen 3000 series and the Ryzen 4000 series to these motherboards. The estimated update package supporting the Ryzen 5000 series processors will be integrated into the code of AGESA V2 PI 1.2.0.7. If users use the latest Zen 3 architecture processors on AMD 300 series motherboards, please look for the BIOS that uses this version of AGESA. AMD and motherboard makers are expected to begin rolling out these new BIOSes in May 2022.
