As discussed in detail, older 300 and 400 series motherboards have been stripped in the BIOS from older CPUs and some features, due to a too-small EEPROM size. No biggy, but MSI is solving this with updated motherboards as well.
If you want to install a Ryzen 3000 CPU on an older motherboard, you will lose support for, among other things, data raid and some older Socket AM4 CPUs. MSI now offers a number of motherboards with a larger storage size for the BIOS. The backward compatibility of Ryzen AM4 is praiseworthy but also presents the board manufacturers with some problems.
The new motherboards get an extra-label called 'Max' and thus have the new 32 MB BIOS. The 300 and 400 series are cheaper than the newly introduced X500 motherboards and thus could be an attractive alternative if you do not fancy PCIe 4.0 These will be the motherboards:
- A-320M-A Pro Max
- B450M-A Pro Max
- B450M Pro-M2 Max
- B450M Pro VDH Max
- B450-A Pro Max
- B450M Mortar Max
- B450 Tomahawk Max
- B450 Gaming Plus Max
- X470 Gaming Plus Max
- X470 Gaming Pro Max
MSI launches new revisions of AMD 300 and 400 motherboards with 32MB Firmware
