Hi, I put together a this build:

ASRock B550m Phantom Gaming 4 AC

Ryzen 5600x

and Corsair 2x8 Gb memory (CMK16GX4M2B3200C16)

Have continuous red lights on DRAM/CPU on the mobo, will not boot/post or any video output when I plug hdmi/displayport into my GPU.

Looking up the QVL for this mobo with the 5600x pairing it looks like that specific model isn't on the list, is this the reason this is happening?

I believe this motherboard has bios 1.20, I see a transparent sticker that faintly says "P.120", and according to ASRock that BIOS should support 5600x.
