Question Need Help Flashing BIOS on ASRock A620M-HDV/M.2 for Ryzen 5 8500G (Stuck on CPU/DRAM Red Light)

[ad0792]

Hey everyone,
I'm in the process of building a new budget PC and decided to go with the Ryzen 5 8500G paired with the ASRock A620M-HDV/M.2 motherboard. After installing everything (CPU, RAM, NVMe, PSU, etc.), I attempted to boot — but the system didn’t post. Instead, I got solid red lights on both CPU and DRAM indicators on the motherboard.

After doing some research, I realized this seems to be a common issue with this board-CPU combo — apparently the board often ships with an older BIOS that doesn’t support the 8500G out of the box.

I came across a Reddit post where someone had the exact same setup, and they managed to get it working by doing a BIOS flash using a USB drive. They formatted their USB to 2GB FAT16, renamed the BIOS file to CREATIVE.ROM, and used the BIOS Flashback button on the board to update it.

I’ve been trying to replicate the process, but things are getting confusing. The ASRock official instructions differ from what users are saying online.

ASRock doesn’t mention anything about renaming the file to CREATIVE.ROM

Some tutorials suggest different formats (FAT32, FAT, FAT16) and file names

There’s also no clear indicator on this board during BIOS flash, so it’s hard to tell if it’s working at all


At this point, I’m really frustrated. If anyone has successfully flashed the BIOS on this exact board (ASRock A620M-HDV/M.2) to get the Ryzen 8500G working, I’d really appreciate some help and a clear step-by-step.

Thanks in advance to anyone who can guide me. You’d be saving my sanity.

and see if your predicament changes/improves.

FYI, I'd have avoided ASRock motherboard's entirely due to their BIOS killing 9000 series processors. A second FYI, is I would've looked into a B850 chipset instead of an A620 chipset board.

Thanks for your reply, I will check that video and if it doesn't work will have to get a new one. I was on low budget and this was cheap. Can you recommend any good boards which I can get without robbing a bank?

Will MSI B650M-E board work out of box?
