Update: We can also confirm that the latest MSI BIOS also supports AMD Smart Access Memory on 400-series motherboards and enables PCIe Gen 4.0 on select models.
MSI has announced a total of 14 motherboards which will be getting initial BIOS support for AMD Ryzen 5000 Desktop CPUs. These motherboards are part of MSI’s MAX family and are based on the X470 / B450 chipsets.

The MSI BIOS support is based on the AGESA 1.1.0.0 which is a BETA release for AMD Ryzen 5000 CPU support. ASRock and Gigabyte are also offering BIOS support for their motherboards based on the same AGESA firmware. ASUS is the only one who prompted to go for the AGESA 1.1.8.0 BIOS firmware which is internally not recommended or intended for consumer use. The AGESA 1.1.8.0 firmware has a few performance issues whereas the AGESA 1.1.0.0 firmware has no impact on the performance using a Ryzen 5000 Desktop CPU.
- ASRock – Unofficial BIOS based on AGESA 1.1.0.0 Firmware (B450 Only)
- Gigabyte – Unofficial BIOS based on AGESA 1.1.0.0 Firmware (X470 & B450)
- MSI – Unofficial BIOS based on AGESA 1.1.0.0 Firmware (X470 & B450)
- ASUS – Unofficial BIOS based on AGESA 1.1.8.0 Firmware (X470 & B450)
An official BIOS (AGESA 1.1.9.0 / 1.2.0.0) is planned for launch in January which will enable support for the AMD Ryzen 5000 Desktop CPUs across all board vendors and will also bring in Smart Access Memory (SAM) support, something which ASRock has already enabled on its 400-series boards with the AGESA 1.1.0.0 firmware.
