“Zen 3” Architecture for 400 Series Motherboards Update
News
We’re excited to
announce the AMD Ryzen 5000 Series desktop processors with the groundbreaking “Zen 3” architecture today. Based on the new levels of gaming performance the 5000 Series enables, we’re certain many of you are already excited to upgrade and making plans to do so. In an effort to keep you informed as promised on
May 19, we’re sharing more on the status of BIOS updates for motherboards with AMD 400 Series chipsets.
The process is underway, and we have already begun providing our motherboard partners with the software code to add Ryzen 5000 Series support for 400 Series motherboard BIOSes.
You can expect the first beta releases of these BIOSes to be available for download starting in January 2021. The BIOSes will be made available directly from your preferred motherboard vendor when they are ready – exact timing and availability will depend on the development, implementation, and test schedule for your specific motherboard vendor and model.
One change from our May 19 update on this topic: Users will not have to verify processor ownership with AMD – we have streamlined the process.
As always, users should verify the processors supported by a BIOS update before flashing, as support for legacy CPUs may be removed to make way for the Ryzen 5000 Series. This may make the update a “one-way” process for some motherboards.
Please confirm you have a processor supported by the new BIOS before flashing to ensure you can boot your PC after the update.
As a reminder, this is the final upgrade path AMD can enable for 400 Series motherboards. Ryzen CPU releases beyond the “Zen 3” architecture will require a new motherboard. We continue to recommend that new AMD customers purchase an AMD B550 or X570 motherboard for the best/easiest user experience.
