Some AMD B450 chipset motherboards may need a BIOS update prior to using Matisse CPUs. Upgrading the BIOS may require a different CPU that is supported by older BIOS revisions.

So, after some time I've saved up for a new PC and went on to a site to check if everything goes together and put the parts I want to take but I get this error "Some AMD B450 chipset motherboards may need a BIOS update prior to using Matisse CPUs. Upgrading the BIOS may require a different CPU that is supported by older BIOS revisions."
The motherboard is MSI B450 TOMAHAWK ATX AM4 Motherboard
The CPU is AMD Ryzen 5 3600 3.6 GHz 6-Core Processor

What does this error mean ? Thanks in advance!

It means that you might get a B450 motherboard which is running an older version of the BIOS which does not support the Ryzen 5 3600. If you recieve a board with an older BIOS the CPU will not work.

Some motherboards are capable of updating the BIOS without a working CPU. Some Asus boards with BIOS flashback for example.

If you want to be sure that the motherboard will work get a X570 board, however these boards are a lot more expensive. You can also ask the retailer if they can update the BIOS for you.

I believe AMD is still borrowing CPUs to people who need to update their BIOS. You can contact AMD if the board does not work and they will borrow you a CPU to update the BIOS.

Ryzen 3000 series wont work with older motherboards like B450, X470 unless they have the updated version of BIOS. Usually you cant update BIOS without CPU so you would need compatible Ryzen 2000 or Ryzen 1000 series CPU to update.
Some of those boards are sold in stores with already updated BIOS and some are not, should have the Ryzen 3000 series compatible sticker on the box if it`s with already updated BIOS.
If you want motherboard that is guaranteed to work out the box then get the new X570 motherbord.

and there a lot of Boards that can do a BIOS update without CPU or RAM installed like all Gigabyte Motherboards, Asus Motherbaords with EZ FLash

I think MSI 'MAX' motherboards are Ryzen 3000 ready out of the box.....any B4xx series MSI motherboard ending with the 'MAX' moniker should be Ryzen 3 ready.

B450 Tomahawk Max boards have an updated BIOS out the box, it'll work fine.
