AMD B550 Motherboard Shown to Run Older Ryzen Processors (non-Matisse)

It appears that AMD’s latest B550 chipset will support older processors such as the Ryzen 5 2600X (Pinnacle Ridge) or even the Ryzen 5 3400G with Vega graphics (Picasso). This is great news for existing Ryzen users who haven’t upgraded to the Matisse yet … PCIE 4.0 here we come!

Taken from TPU … The AMD B550 chipset isn’t supposed to run 1st- and 2nd-generation AMD Ryzen processors, or even Ryzen 5 3400G and 3200G APUs based on the older “Zen+” microarchitecture. AMD specifically made a packaging badge that reflects this. The B550 chipset only supports 3rd gen Ryzen “Matisse,” and is ready for upcoming “Renoir” and “Zen 3” based “Vermeer” processors, when they do come out.

Given this, imagine our surprise when someone with access to a B550 motherboard was able to run older processors on it. PC enthusiast 188 “momomo_us” posted screenshots of an ASUS TUF Gaming B550M-Plus motherboard running “Zen+” based Ryzen 5 3400G APU based on the “Picasso” silicon, and Ryzen 5 2600X processor based on the “Pinnacle Ridge” silicon, complete with CPU-Z validations. The board is shown running BIOS version 0608 (dated 15/06/2020). There’s nothing in the official change-log to indicate Zen+ support, nor in its CPU support list, and the CPU-Z screenshots don’t reveal AGESA version in the BIOS version string. An impressive feat nonetheless. We still can’t recommend taking the risk of buying B550 motherboards with older processors. Find the CPU-Z validation for the 3400G+B550 and 2600X+B550.
