AMD documents AM4 as DDR4 and publishes a chipset-by-processor-family support matrix.
A matching socket and memory generation are only part of the check. The exact board's BIOS, module type, capacity and memory-support list still matter. The listings below are filtered by generation, not a claim that every kit works with every board.
