Translated with ChatGPT:
Why does it suddenly stop booting one day?
→ Because of a BIOS update, even though it was running stably. (This issue does not occur unless the BIOS is updated.)

What are the specific conditions for this issue to occur?
→ The issue is caused by some older DDR5 RAM and certain memory controllers on X3D CPUs, as well as the impact of Agesa.

Why does the CPU boot if it is RMA’d (returned/exchanged)? What exactly happens to the CPU that makes it stop booting?
→ The memory controller on the CPU changes.

Where does the responsibility for this issue lie (Is it AMD’s fault, the motherboard manufacturer’s fault, or both)?
→ It is caused by a very specific combination of components. I would like to know where the responsibility for the damage and the spreading of false information lies as well.

What is the specific cause of this issue (It’s said to be a memory compatibility problem, but what exactly is happening)?
→ As mentioned above, it is the combination of older DDR5 RAM, certain memory controllers on X3D CPUs, and the influence of Agesa.

Is there anything users can do in advance to prevent encountering this issue?
→ This is very important, so I’ll say it three times: If it’s running stably, do NOT update the BIOS.
Do NOT update the BIOS if it’s running stably.
Do NOT update the BIOS if it’s running stably.
