When AMD announced the Ryzen 5000 processors it confirmed that they would only be compatible with the A520, B550, X570 motherboards, and the older AMD X470 and AMD B450, although these will be supported in January 2021.
This means that even older motherboards, such as those with an AMD 300 Series chipset, would not be directly supported, until now, as various AMD partners, such as Asus, ASRock and Gigabyte, have disclosed that their motherboards AMD A320 and AMD X370 will be compatible with AMD Ryzen 5000 processors, what’s more, two of these companies have already given access to a Beta BIOS that offers support.
From the Chiphell forums, it has been shown that an ASRock A320-HDV motherboard was even capable of running smoothly with a 12-core AMD Ryzen 9 5900X along with 16 GB of DDR4 RAM, and even with an AMD Ryzen 4000G APU, thanks to a new and unknown BIOS BETA.
Gigabyte and Asus have already made their BETA BIOSes available to support AMD Ryzen 5000 CPUs from an AMD B450 motherboard without waiting until 2021. Gigabyte is offering BETA support on a total of 16 motherboards based on the B450 chipset while that ASUS is offering BETA support on a total of 16 ROG STRIX, PRIME & TUF gaming products. Gigabyte BIOS has been christened F60c while Asus BIOS is 8501.
