Repairing A Couple Of Very Expensive Registered DDR5 RAM Sticks

A repair shop was handed two failing registered ECC DDR5 RDIMMs by businesses rather than having them discarded, given their high market value. The 128GB stick failed DDR5 training due to a cracked solder joint and was fixed with a reflow cycle. The 256GB stick was dead due to a shorted MLCC filter capacitor and a broken PMIC, likely caused by being dropped, requiring extensive reballing and troubleshooting including SPD ROM swapping and reprogramming before being resolved.
