How to make sure your motherboard is ready for AMD Zen 3

You'll need to update your BIOS not once, but twice.

If you've been waiting anxiously for weeks to drop AMD's new Zen 3 Ryzen 5000 into your 500-series motherboard, the time is nearly upon us.

You will have to do a few things to prepare your 500-series motherboard first, though. AMD official said for any 500-series motherboard to boot a new Zen 3 chip, it'll have to have a UEFI/BIOS featuring an AMD AGESA BIOS numbered or higher.

You can head over to your motherboard maker's website and search the support section for the BIOS for your board. For example, for this Asus Prime X570P, we found that Asus currently has a BIOS/UEFI version of 2606 on its website that was released in August of 2019. The descriptions for the BIOS/UEFI show that it incorporates AMD AGESA version To install it, we'd download the file, decompress the file onto a USB stick, and then reboot into the BIOS.

You'll need a BIOS/UEFI with at least AMD AGESA to boot a new Zen 3 CPU in your 500-series motherboard.

From there we'd use the built-in flash BIOS tool to update to the BIOS from the USB stick. We're not going to get into too much granular detail, as the method does vary from among vendors. Some also offer different methods to update a BIOS, including OS-based updaters.

With the AGESA installed, AMD said the board will properly boot a Zen 3 / Ryzen 5000 chip. But the just allows the board to POST the new CPU. On November 5, you should check your motherboard vendor's site again for a BIOS featuring the AGESA, which will incorporate more optimized features for the Zen 3 chip.

And yes, we do think it is recommended that you run the latest AGESA to extract the most performance from the new CPU.

What about AMD 400-series users?

All this advice applies to those with 500-series motherboards. For folks still using older 400-series motherboards, you're going to have to wait a few months more. AMD officials said BIOS updates for older motherboard users are currently in development by board makers. You probably shouldn't expect support until January of 2021.
