Exploding AMD CPUs | Investigating ASRock's Murderboards

Sponsor: ID-Cooling Frozn A720 Black on Amazon https://geni.us/VDnou4Y
ASRock motherboards have been killing AMD CPUs all year, and in particular, the AMD Ryzen 7 9800X3D CPUs. The mystery has been unsolved for 9 months now (and remains unsolved), but ASRock and AMD are both investigating, as are we. In theory, they should find an answer before us -- but for whatever reason, it's been complete silence from both companies beyond some blame-gaming between them. In this video, we do our best to test for internet theories as to the root cause of ASRock's murderboard failures that cause the destruction of X3D CPUs.
