The ASUS B550-F continues to show the DRAM light with flashing after the repair was issued via RMA.

TL;DR: PC won’t boot due to DRAM light on the motherboard. Replacing RAM didn’t help. An ASUS RMA was attempted but likely ineffective. Possible causes range from motherboard issues to BIOS problems. I’ve tried several fixes and still face uncertainty. The most probable culprit seems to be the motherboard itself, though other parts could be involved. I’m seeking guidance on whether to pursue an ASUS fix or get a replacement sooner.
It seems the CPU might be faulty, possibly due to a failing memory controller.
Thanks, it makes perfect sense too. Thought a CPU problem would be clear-cut—works or doesn’t. I’ll start an AMD RMA and see if that fixes it. By the way, once my issues are resolved, I’ll share my 3080 and 680 BIOS files with your database.
Because the memory controller is now built into the CPU, it might be the sole component failing, leading to a system crash.
I have now selected "bad CPU" as the correct choice. AMD has received my return request and approved a replacement. For those facing similar problems, handle the cooler removal with care—follow the manufacturer’s guidelines. It’s wise to gently twist the detached cooler while pulling it off slowly to avoid damaging pins or thermal paste. Any scratches or nicks may invalidate your warranty, particularly if they hide the ID numbers or QR code on the CPU. For troubleshooting, return or replace the RAM, motherboard, and CPU as soon as possible through the retailer you bought from. Otherwise, expect a 2-week wait for an RMA, even with fast processing (ASUS: 1-2 days, AMD: 1 day). Pickup shipping may add an extra day or two. It would be helpful to have an extended warranty, but right now it’s about staying attentive to return deadlines. I understand that replacements at the store can be limited by their inventory. AMD RMA advice: They’ll need a photo of your processor in the socket, clearly showing the model and serial number. Write your service request on paper and include both the CPU serial and your SRN. Keep the BIOS version handy. Make sure to read all their shipping and RMA instructions via email. So far, they haven’t shared tracking details for the replacement shipment—they just say to expect delivery in 5 days and contact support if it’s delayed.
It finally worked after three years. However, in recent months I've faced other problems: currently the main concern is that the NVME drive I inserted into the M.2 slot isn't being recognized. I'm still open to possibilities like a motherboard or CPU issue, but at least RAM, GPU, and Windows 10 are no longer contributing to the problems.
