Question No signal when using new cpu, but works with an older cpu.

[UyKerad]

I recently got a new CPU (Ryzen 5 5600) to replace my old one (Ryzen 3 1200). I have a b450m ds3h motherboard. I updated the BIOS of the motherboard to the latest version and it works with the older CPU. However, when I use the newer CPU, it doesn't work. PC turns on, just No Signal to the monitor.

I also tried resetting the BIOS (the two pins and the battery), so I'm confused as to what else I can do.

Yes but f62 is what's needed to support the cpu so start there.

Ok, I'll try that!

Seems like it didn't work. I still have the same no signal problem.

Nevermind, turned it off and on again. Works now. Thanks.

Good deal. On my Asrock b350 board, at least when I went to my ryzen 5 3600 you had to install a bridge bios before you could install the needed bios for the cpu. Sometimes as well when you swap cpus it may have to cycle a couple of times.
