Question B450M Mortar Max and Ryzen 5 5600x

[SandyDuk]

Hi everyone,

I've just bought my son a Ryzen 5 5600x as an upgrade but pc won't boot now. The cpu light is on the ezdubug on the board. I've used mflash to get to the latest bios version but still no joy. Any advice is welcome ...

Mortar Max B450M MS-7B89 AM4

bios flashed to v2.k0 20/10/2023

Ryzen 5 5600x

Thanks in advance, Sandy

Hey there,

Are these new components?

WHat are the other specs of the PC. WHat PSU, make and model. Are you sure the PSU is functional? Tested on another system?

I'm working on the assumption that this is a CPU upgrade for a system that was already known working.

That BIOS date and naming doesn't quite match the MSI site (2023-10-26/v2K) is this a prebuilt system?

What CPU was in there before?

Does the old CPU still work?

 

[SandyDuk]

Yeah, all working with the old cpu at the moment, but if I swap for the new cpu then it won't boot.

Bios details came from speccy. I did download the latest from msi website for B450M though.

Current cpu is ryzen 5 5600

Thanks

Sounds like the CPU is bad then because they both have the same base TDP so there's no technical reason the new one wouldn't work with what you have.

Just as a piece of information the 5600X is rather unlikely to give any meaningful performance increase over the non-X.
