Since AMD released the Ryzen 5000 (Vermeer) processors, many motherboard manufacturers have upgraded the BIOS to allow some old motherboards to provide support, but there are not many motherboards based on the 300 series chipset. Although ASRock provided Beta BIOS for its 300 series motherboards in the early days, and ASUS and Biostar later provided related BIOS on A320 motherboards, but more manufacturers and products did not follow up. It has been rumored that the reason is that AMD does not want manufacturers to do so, so even if a manufacturer provides BIOS in this regard, it is either always in Beta state, or does not make specific instructions and publicity.
In an interview with TomsHardware, David McAfee, AMD vice president, and general manager of customer channel business said that it is not a good thing that 300 series motherboards do not support Ryzen 5000 series processors, and AMD won’t leave it alone and is currently working on making it a reality. In fact, this issue has also received attention and discussion within AMD and is currently researching how to make the 300 series motherboard support the Ryzen 5000, users can get the correct experience.
At present, the 300 series motherboards that can support Ryzen 5000 processors are mostly low-end A320 motherboards. The mainstream B350 and X370 for high-end users have not achieved the same operation, which has attracted criticism from many users. Although some enthusiastic technology enthusiasts have found some workarounds and provided self-made BIOS, stability and applicability are always lacking.
David McAfee said that the small BIOS capacity of early 300 series motherboards brought great complexity to maintaining product support, and validating and choosing which products to support required making difficult choices. In addition, the 300 series motherboards differ from the later motherboards in the AM4 ecosystem in some design requirements. Without careful verification, blindly choosing to support these Zen 3 architecture processors may have a great impact on performance, and there may also be some hidden problems.
