There should be a sticker on the chipset with the current bios number. https://www.asrock.com/support/index.us.asp?cat=FindBIOS

Your MB needs bios V1.60 for the ryzen 5 5600X. https://www.asrock.com/mb/AMD/B550%20Phantom%20Gaming-ITXax/index.asp#CPU

That's a recent bios release, 11/4/2020, so your MB may not have it. https://www.asrock.com/mb/AMD/B550%20Phantom%20Gaming-ITXax/index.asp#BIOS

Hi. I am testing my build out.

I bought my Board, a ASrock B550 Phantom Gaming ITX on September 5th in preparation for Zen 3. Got a 5600x at launch.

[Link to my build here](https://pcpartpicker.com/user/ravage123/saved/k3qk99). I don't have a 3080 yet and have been trying to get it to boot with a GTX 1070 and a RX 580.

At first I tried the Rx580, and the lights and fans would not turn on at all. Then I tried the GTX1070 and it seemed to turn on fine. Fans spun up, lights stayed on.

The Case/CPU/GPU fans, turn on, GPU/motherboard lights turn on. I've tried different display outputs, monitors, and 2 different GPUs, and its the same result. No display signal or POST screen.

Reseated the RAM and GPU as well.

I'm stumped.... Maybe my motherboard doesn't have a BIOS that supports Zen 3? No way to check since I don't have a Zen 2 CPU.

How can I check the currently installed BIOS without being able to boot? I know ASrock has the BIOS version written on a sticker somewhere but I am unable to find it on this board.
