About the Samsung 64GB DDR4 LRDIMM M386A8K40BM2-CWD
Samsung 64GB DDR4 LRDIMM M386A8K40BM2-CWD delivers CL21 latency at 1.2V—ideal for high-frequency trading platforms and in-memory database workloads where timing precision directly impacts throughput. This enterprise-grade module combines quad-rank density with load-reduced architecture, enabling scaling across dual-socket and multi-socket server environments without sacrificing signal integrity or thermal performance.
The M386A8K40BM2-CWD operates at DDR4-2933 (PC4-23400), providing 23.4 GB/s peak bandwidth with full ECC protection across all 64 bits of addressable memory plus parity. Engineered for mission-critical applications, this Samsung LRDIMM fits into standard 288-pin sockets and maintains a compact 31.25mm height for dense server configurations. Storage architects, hyperscaler procurement teams, and data center engineers standardize on this form factor for its reliability and compatibility with major OEM platforms. The quad-rank, x4 device configuration (4Rx4) reduces the number of modules required per server while maintaining performance headroom across NUMA-aware operating systems and virtualization stacks. JEDEC compliance ensures vendor interoperability and long-term supply chain stability.
