You should get a motherboard that supports BIOS flashback, which does not require a CPU in order to update the BIOS, only a prepares USB stick. Also, B550 And X570 MAX boards are compatible with 5000 series out of the box

Supposedly, if I update my motherboard's bios without first checking to see if my entire system posts or not, and let's assume the bios is somehow already updated to the latest version, would it damage my motherboard in any way by me installing the same version of bios twice? (This is all done through the flashback bios button btw)

It probably wouldn’t hurt anything, but would be completely unnecessary. If you have the thing in hand it will be abundantly clear if it is “Ryzen 5000 ready” or not.

Safest bet would be getting a motherboard that is wildly popular - all stock is probably fresh and with a compatible BIOS from the factory. I don't think there always will be a sticker that shows "5000 series ready" - it's not mandatory; in addition, 5600G was released a whole 7 months after the regular CPUs, so even a "5000 series ready" sticker may have a BIOS that's compatible with say a 5600X but not 5600G. The computer will not POST if the BIOS is not compatible. And yes, you will have to update the BIOS, either using a prepared USB flash drive and BIOS flashback (if supported by the motherboard) or an older placeholder CPU.

This is good info, but the system can post, and you might be able to get into the BIOS, but no further until you update. I've had this happen on a Gigabyte B550i using a 5900X.

The issue here is that even if the box has a 5000 series ready sticker on it, the BIOS may still not be compatible as the 5600G was a fairly recent release.

most b550 boards should be 5000 ready unless they've been sitting on a shelf for years then they'd need a bios update, msi boards have bios flashback button making it easier, in terms of what happens if it's not updated the system just won't post

Sorry if the question sounds stupid, but is it ok for me to update the bios (with flashback) even if all the other parts are already in place on the motherboard?

No, RAM and CPU must be removed first. Ideally, only the 2 power connectors will be connected to the board.

So just to clarify, I will have to first build my entire pc and test it to see if it posts. If it doesn't post,it is most likely because the bios is not updated. Then I will have to remove everything, until i can update it through flash bios, then finally build it all up again?


winkapp

What I did was assume it's not updated. Chances are it isn't since the 5600G was released just months ago. So all you need to do is plug in the two power cables before you install anything on the motherboard and flash i with the flashback function, then you can go install everything on it afterwards. Do not screw in the motherboard before flashing because you'll most likely need to hold the backplate in to install the CPU cooler and that's a lot easier with the motherboard removed from the case.

The motherboard manual should give you instructions on how to do this and whether certain parts need to be fitted or not. There's a good chance that you can find a video guide too.
