Spotted by Techpowerup.com and featuring AGESA v1.1.0.1 firmware, the BIOS updates will bring support for the upcoming Ryzen 3 2200G and Ryzen 5 2400G APUs. In addition to the added Raven Ridge support, it appears that the BIOS update also improves memory support with some users reporting that 3200MHz is now achievable.
The list of motherboards includes anywhere from the high-end X370 lineup with the XPower Gaming Titanium, over the B350 lineup with Tomahawk, Gaming, and other series, down to the A320-based motherboards like the A320M Gaming Pro.
The BIOS update will be available in the download section for each AM4 motherboard so even if you are not shopping for the new Raven Ridge APU, better memory support is certainly enough to warrant the update.
