A feature that is appreciated by many was adding support for Smart Access Memory aka resize BAR functionality on the Ryzen 5000 platform. AMD yesterday also announced that Ryzen 3000 will get supported.

AMD reports that users with Ryzen 3000 systems can update their BIOS with Agesa version 1.1.0.0 to get that support enabled. The feature however only works on series 500 chipset-based motherboards with (X570 or B550). Smart Access Memory will not work on Ryzen 3000G APUs, such as the Ryzen 5 3400G and Ryzen 3 3200G.

A secondary requirement is that you need to own a Radeon RX 6000 video card to use Smart Access Memory.  The recently released GeForce RTX 3060 also supports the feature. Other RTX 30 video cards will also receive support for the feature via a bios update. Intel as well has added the feature to its Z490 and soon Z590 chipset.

If compatible and you'd like to try it out, seek Re-Size BAR Support' and 'Above 4G Decoding' in your BIOS.
