    "AMD Zen 3 Ryzen 4000 Motherboards
    With a new wave of chips about to crash down on the market, the first question on enthusiast's minds is: Can I drop a Zen 3 Ryzen 4000 chip in my motherboard?
    If you have a B550, X570, B450, or X470 motherboard, the answer is yes. Ryzen 4000 series processors will drop into the tried-and-true AM4 socket, and AMD will support the chips on the aforementioned chipsets. Enthusiasts with 300-series motherboards are left in the cold, though, but you're probably better served by stepping up to more modern accommodations anyway.
    The new BIOS revisions for existing 400-series boards will enable the full functionality of Zen 3 processors. However, you will still not gain access to the PCIe 4.0 interface on B450 and X470 motherboards (they don't support the interface). AMD says the 400-series BIOS updates come as a one-way path: You can flash your motherboard to the new firmware, but you will not be able to flash back to previous BIOS versions that support pre-Zen 3 processors.
    AMD will also require an as-yet-undefined process that verifies you have purchased a Zen 3 processor. AMD says that verifying a customer has purchased a Zen 3 processor is designed to prevent irreversible BIOS flashing issues, but AMD's reasoning behind the forward-only flash requirement is unclear.
    AMD's updates also mark the end of the line for 400-series motherboards: AMD will not support future processors on the platform."

    de hogy miként fog majd a frissítés végbemenni az még titok :F
