Not just crumbs in the CPU socket: Over 100 AMD 9800X3D chips are now reported to have gone pop and the most by far have died in ASRock motherboards

AMD Ryzen 7 9800X3D processor.

Update, April 2, 2025: AMD has given us a statement regarding the reportedly dead Ryzen processors, and we are pursuing further clarification from AMD. The statement notes that after an investigation between AMD and ASRock it has been decided the issue is down to memory incompatibility rather than the CPUs themselves being broken. Which doesn't necessarily jibe with the reddit reports, it has to be said:

We are aware of a limited number of user reports involving ASRock AM5 motherboards failing to complete POST. Following a joint investigation, AMD and ASRock identified a memory compatibility issue present in earlier BIOS versions, which has been rectified in the latest BIOS. ASRock has already issued guidance on this behavior and addressed a singular report of a damaged CPU.
