Dual in-line memory modules provide high-density random access memory for computers and servers. They feature separate electrical contacts on each side of the board edge, allowing a wider data path than older single in-line modules. They connect directly to the motherboard memory slots and are classified by generation, such as DDR4 or DDR5, and pin count.
Make sure to seat the DIMM firmly until the side latches click into place.
