ASRock Brings Zen 3 Support to A320, X370, and B350 Boards with Beta BIOS Update

ASRock has released the beta BIOS updates for the older 300 series chipsets, including the A320, B350, and the X370 boards bringing Zen 3 support to pre-Ryzen 3000 hardware, despite AMD’s initial statement that support would be limited to the 500 series boards (later overturned). Even now, AMD is officially offering Zen 3 support on just the B450 and X470 boards via a one-way BIOS update expected to be available to verified buyers of the Ryzen 5000 chips.

While many OEMs have released beta BIOSes supporting the Vermeer parts on the 400 series boards, ASRock remains the only vendor allowing users to run the Zen 3 CPUs on even the A320 boards. We’ve already seen a bunch of modified BIOSes for the 300 series boards that reportedly support the Zen 3 processors but these files were from an unofficial source.

Supported boards

This latest bit of info comes from HKEPC (via WCCFtech). According to the outlet, ASRock sent them a number of BIOS files for its A320, B350, and X370 boards, all supporting the Ryzen 5000 CPUs. The BIOSes were tested and all appeared to be working normally (through POST and burn-in with normal results), but there’s no guarantee whether they are suitable for 24/7 hour use. The AGESA version is 1.1.0.0. We’d recommend using the A320 and B350 boards only with the Ryzen 5 5600X while the X370 with the Ryzen 7 5800X. It’s not recommended to pair these boards with the Ryzen 9 5900X or the 5950X, as performance will likely not be up to the mark, or you run into instability issues.
