Strix B550-F Gaming (Wifi) stuck on DRAM led, BIOS flashback not working

I did all of your suggested steps, but the issue still remains.

The DRAM led lights up directly and just stays on. What could have caused the intermitent POST previously? The board looks fine physically from what I can see...

As you've already tried another CPU, probably an idea to contact service. I've moved the thread to ROG Care so the team can try to help you, but consider contacting service for your region 👍

Hello, @infinipix 

Could you confirm if your current installed memory is listed on the ROG STRIX B550-F GAMING (WI-FI) Memory QVL?
We recommend performing a bare-board test to verify if the MB is able to boot into BIOS:
Install only the 3200G CPU on the MB and use onboard video output, install a single RAM module in the DIMM_B2 slot (not A2), connect the PSU, and clear CMOS before powering on.

Additionally, based on your description, is the second-hand MB you purchased in good condition?
Have you confirmed the reported issues with the previous owner?

Thank you.

Hi, @Jiaszzz_ROG 

I tried with a stick of memory, known working and on the QVL in slot B2, with the 3200G as you suggested, but it still will not POST.

The board is in very good condition visually, no sratches or bent pins or anything like that. The previous owner had the same issue, but hadn't the equipment to troubleshoot.

Hello, @infinipix 

Based on your description, you have conducted various cross-tests and the previous owner also experienced this issue.
We recommend sending the motherboard for repair for further diagnostics.

Thank you.
