By any chance anyone on this forum could mod the B350 PC MATE motherboard bios to support latest Ryzen 5000 series?
There is this for 320 https://www.chiphell.com/thread-2274538-1-1.html
Request still valid =(
This just got out https://www.reddit.com/r/Amd/comments/k3…50_gaming_plus/
No one will do such mod.
The bios will need to have a new AGESA V2 for Ryzen 5000 support. There is no known method to just replace the old AGESA with a new one.
Your best bet would be crossflashing with a B450 bios. Look for a bios from a B450 board with the same Multi I/O chip (Nuvoton NCT6795) and a 16Kb ROM size.
