Motherboard manufacturers are prepping for the imminent release of the AMD Ryzen 3000 CPUs with new BIOS updates for existing motherboards. We are, of course, expecting them all to take advantage of a new range of CPUs and chipsets by releasing a slew of brand new 500-series motherboards, but thanks to the backwards compatibility of the AM4 platform you will still be able to run Ryzen 3000 processors in old school motherboards.

Though not all of them. The new batch of MSI, Asus, and Biostar BIOS updates have rolled out to existing X470, B450, and X370 motherboards… but not for the B350 boards. There had been earlier speculation that the lower end of 300-series motherboards wouldn’t be compatible with the new AMD Zen 2 CPUs, despite the original AMD assertion of AM4 CPU compatibility up to 2020.

Support, however, could be left up to the actual motherboard manufacturers themselves, however, as it’s possible the only real restriction on the B350 boards is the capacity of the BIOS chip itself. Higher-spec boards sport 32MiByte chips, while the B350s only have 16MiByte capacity BIOS silicon.
