Hello,

I am thinking about replacing the R5-1400 in my system with an R5-5600 rather than jumping to AM5 given the price. Seems like a good and cheap drop in upgrade to keep this system chugging along.

I am on BIOS p5.40 right now. If I am reading correctly, I can flash P7.00 [Beta] and then L8.02. Is that correct, or are there any bridge BIOS' I am missing? And to confirm, would I be able to use the 1400 to flash from 5.40 up through L8.02?

Thanks in advance!

My advice, don't use the 5000 series CPU's, but stick to the CPU support list.
https://www.asrock.com/mb/AMD/AB350%20Pro4/index.asp#CPU
5000 sereis is not on the support list and can only function because AMD put that in the Agesa code, and sometimes it works for a short while, and suddenly 1 memory slot stops working, with the Old CPU there is no problem, and when you put the new CPU on an newer board, there is also no problem
Also a new BIOS doesn't mean, that it is always betetr, that is a misperception, many people have.
When your BIOS is 5.40, indeed you need to go to the 7.00 bridge BIOS, then You can update to 8.02.
But You cannot downgrade anymore, once You have 7.00 or above.
Kind Regards

Thanks for your insight. If there is no confidence in the 5k sku's in the b350 boards, then this machine is end of the road. I don't see any reson in adding a 3k series sku to this given how old it is.
