Samsung 64GB DDR4 2133 Mbps Server Memory Module

The Samsung M386A8K40BM1-CPB is a 64GB DDR4 memory module built for servers that need large amounts of dependable RAM without sacrificing signal quality. As a Load Reduced DIMM, it places a data buffer between the memory chips and the host controller, which lowers electrical load and helps maintain stable performance when multiple modules share the same channel.

Running at 2133 Mbps with a low 1.2 V operating voltage, this module balances speed with energy efficiency, an advantage for data centers that watch both performance metrics and power budgets. The 4-rank by 4-bit organization and 288-pin layout follow common DDR4 server standards, making installation straightforward in systems that accept LRDIMM technology.

Administrators who manage virtualization clusters, in-memory databases, or high-performance computing nodes can use this module to push system capacity to 64 GB per slot. The load-reduced design is especially helpful in configurations that populate all memory channels, supporting steady throughput even under heavy, multi-threaded workloads.

Before ordering, confirm that the target server supports DDR4 LRDIMM modules. When the platform is compatible, the Samsung M386A8K40BM1-CPB gives IT teams a practical path to expand memory density and maintain consistent uptime in demanding enterprise environments.
