An unofficial BIOS has popped up which allows the Ryzen 5000 series CPUs to run with X470 and B450 series Motherboards for now. According to AMD’s road map, the official BIOS update is planned to arrive in January which will bring support for the Ryzen 5000 CPU & SAM (Smart Access Memory) support on X470 & B450 motherboards.
However, some motherboard manufacturers have started to release unofficial BIOS with support for Ryzen 5000 CPUs on their boards based on the 400-series chipsets. Currently, only AMD’s 500-series motherboards (X570 and B550) have the official BIOS to support Ryzen 5000 Desktop CPUs and Smart Access Memory technology.
However, multiple board manufacturers have released unofficial BIOS on an older AGESA firmware and not the official one which will be launching in January. ASRock released the first unofficial BIOS support for AMD Ryzen 5000 Desktop CPUs on its B450 line of motherboards and it is based on AGESA 1.1.0.0 firmware.
Then it was Gigabyte who released a BIOS update for their B450 motherboards also based on the AGESA 1.1.0.0 firmware. However, ASUS has gone one step ahead of others and has released unofficial BIOS for its entire X470 and B450 line of boards. The BIOS is based on the AGESA 1.1.8.0 firmware and according to AMD, the 1.1.8.0 firmware is not meant to be released to the public or marketed which ASUS has done so far.
According to various rumors, AGESA 1.1.9.0 is under development and suggests that the version will be known as 1.2.0.0 once it is available to the public and it is the version that will officially bring the Ryzen 5000 series support to the X470 and B450 motherboards. Motherboard makers are also adding unofficial BIOS support for AMD’s Smart Access Memory tech in their boards. ASRock seems to have already done so by enabling this feature in the BIOS mentioned above.
