Hi

I'm having some throuble to boot up my system. Sunday I bought this the B450M-HDV R4.0 mobo, installed my Ryzen 5, wich is supported since BIOS 4.5.
But, no boot, nothing. Had to change back to the Ryzen 5 1400 to update the BIOS to the last version, but, still no boot. What should I do? The CPU is fine, I tested it before buying.

EDIT: I found out the reason. AMD has a “feature” called PSB, and since i tested the CPU in it’s original motherboard, worked just fine.
Now i have to find another CPU, hopefully unlocked or return the mobo.
Thanks for the supports and insights!
