ASUS has become the first motherboard manufacturer to roll out the latest AMD AGESA 1.2.0.3 Patch C for its X570 ROG lineup, offering improved compatibility with upcoming desktop CPUs & APUs.

The AMD AGESA 1.2.0.3 Patch C BETA BIOS is an extension to Patch B which was released last month and aside from extending support to the Ryzen 5000G APUs (Cezanne) and Ryzen 5000 CPUs (Vermeer B2 Stepping), it also resolved all USB issues on Ryzen 5000 systems.
