With the launch of the AMD Ryzen 3000-series CPUs this week, MSI announced that it's updating its AMD 400-series motherboards with bigger BIOS chips to provide support for the larger database of AMD processors.
As AMD's family of processors continues to grow, MSI finds itself in a sticky predicament. The BIOS chips on some of the brand's 300-series and 400-series motherboards have run out of space to store the microcode and memory training tables for every single AMD processor.
ASMedia won't start shipping B550 and A520 chipsets to motherboard manufacturers until the fourth quarter. Therefore, the corresponding motherboards won't arrive until the end of the year or possibly until next year. So, there is still demand for 400-series motherboards among Ryzen 3000-series adopters who don't want to opt for the more expensive X570-based motherboards.
MSI has already released Beta BIOSes for a number of older AM4 motherboards to support the new Ryzen 3000-series chips. However, the motherboard manufacturer had to make a lot of sacrifices to make this happen. For starters, it removed all the eye candy from the BIOS interface. All the cool and flashy elements from the "Click BIOS 5" interface were replaced with a boring black background and simple icons. MSI calls this new interface "Click BIOS (GSE Lite)."
In order to squeeze in support for the new third-generation Ryzen chips, MSI also dropped support for the A-series and Athlon Bristol Ridge APUs, such as the A12-9800, A10-9700 and Athlon X4 970.
Many users can probably live without Click BIOS 5 and support for the archaic Bristol Ridge APUs. However, the biggest disappointment from MSI's stop-gap solution is the elimination of the RAID module. If you upgrade to the Beta BIOS, you will basically lose all RAID functionality, which means saying goodbye to your existing RAID array. And you won't be able to create a new one in the future.
Polish media PurePC recently reported that MSI will substitute the 16MB BIOS chips that were previously used on A320, B450 and X470 motherboards with 32MB ones. The refreshed motherboards will reportedly carry the MAX suffix (example: X470 Gaming Pro MAX or B450M Mortar Titanium MAX).
