We've all heard the advice by now not to believe everything you read on the Internet. The latest example is the rumor that Asus will not support AMD's new Ryzen 5000 series processors on its 400 series motherboards. In a statement released on the Internet, Asus simply states that it is not true. So which should we believe?

Asus. Because the idiom "straight from the horse's mouth" trumps sensible but vague advice, Asus has declared the rumor to be "disinformation and incorrect," and has stated that it plans to roll out a BIOS update to X470, B450, and B450 II motherboards to support AMD's next CPU He stated that he plans to roll out a BIOS update to X470, B450 and B450 II motherboards to support AMD's next CPUs.

"I have seen recent forum posts that the X470 and other 400 series boards are not supported by Asus for AMD's 5000 series processors. This is incorrect and incorrect information," Asus said in an emailed statement.

"To clarify, Asus will release a new BIOS for X470, B450 and B450 II motherboards in accordance with AMD's support plan, and all motherboards currently available on the market will also support that BIOS upgrade."

Asus added, "AMD's guidelines and timeline, which means the beta BIOS support will be ready for deployment around January 2021.

AMD's recently announced Ryzen 5000 series is based on the company's latest generation Zen 3 architecture, which the company claims offers a 19% increase in IPC (instructions per clock) over Zen 2: Ryzen 5 5600X (6C/12T, $299) Ryzen 7 5800X (8C/16T, $449), Ryzen 9 5900X (12C/24T, $549), and Ryzen 9 5950X (16C/32T, $799).

One of the attractions of the Zen 3 is that AMD has decided to stick with the AM4 socket for another round. The original plan was to limit support primarily to 500 series motherboards (and a few specific high-end X470 boards), but after community outcry, AMD changed its guidelines. [because AMD provides the base AGESA code on which custom BIOS firmware is built]. By deciding to extend backward compatibility to X470 and B450 motherboards, AMD's hardware partners will be able to support the upcoming processors with By deciding to extend backward compatibility to X470 and B450 motherboards, AMD's hardware partners were assured that they could provide firmware updates to support the upcoming processors.

As this applies specifically to Asus, confirmation will be made at a later date as to which motherboards will need to be upgraded with the previous generation CPUs. However, all new Asus B450 II motherboards will include a USB BIOS flashback feature that allows the BIOS to be updated with the new CPU installed.

On the other hand, if you own an X570 or B550 motherboard, BIOS updates supporting Zen 3 have already begun. Keep in mind that these initial updates are primarily focused on supporting the Ryzen 5000 series, and later updates will be more optimized for the new CPUs.
