Last week, we saw the first public rollout of AMD's latest AGESA 1.0.0.5 microcode for AM4 boards which adds improved compatibility and support for Ryzen based systems. The AGESA 1.0.0.5 was delivered by MSI first on its MAX series (A320, B450, X470) motherboards but now, MSI is rolling out the BIOS update for its entire X570 lineup including a few new additions.

As expected, the AMD AGESA 1.0.0.5 BIOS firmware BIOS landing on MSI's X570 motherboards is a BETA version while the 300/400 series motherboards are releasing a final version BIOS. MSI will be releasing the BETA BIOS for 9 X570 motherboards, which is in addition to the 13 X470, B450 & A320 motherboards that have already received it.

Optimized PCIe firmware to improve stability and interoperability
The BIOS definitely seems to offer improved stability and optimizations in regards to DDR4 DRAM compatibility and also generation PCIe stability and interoperability. Those who are still running an older BIOS should definitely try out the new BIOS but if you are not facing any issues with the ones you already have, then it's better to stick with it. If your motherboards aren't made by MSI, then don't worry since as mentioned above, motherboard manufacturers will be releasing new BIOS for their own specific lineups this month. We will keep you posted as more motherboards receive the AMD AGESA 1.0.0.5 update.
