B450M Pro4 BIOS issue

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello

I was wondering if anyone could help. I bought a B450M Pro4 second hand. I was told upon purchase that the boards bios has been updated so I built my new system with a Ryzen 5 5600.

When booting the system it seems to be stuck in a loop, resetting after theory seconds. I do not get any signal to my monitor and cannot get into the BIOS. I have also tried removing ram to see if that fixed it. I am not getting any error sounds when booting.

I suspect that the BIOS has not fact been updated to run 5000 series CPUs. and that is my issue. I do not however have access to an older CPU to update it.

Is there another way to fix my issue?

Thank you in advance for any help.

	Maybe you can borrow or buy an old/cheap CPU. I had a 2600 and I was told by ASRock to update the BIOS right before putting in a 5600. They warn against updating the BIOS past a certain point with old CPUs. Unfortunately I don't have an easy fix suggestion. I'd ask ASRock if there is a way to update the BIOS without booting. I think MSI boards can.

	Thank you for your response. I believe I will need to buy another older CPU to update the bios but I will look into this first. Thanks again

	See if AMD still offers "Short Term Processor Loan Boot Kit" I'm so glad most (all?) AM5 boards have BIOS flashback (or whatever it's called) feature.
