About the Samsung 128GB DDR4 LRDIMM - DDR4 (M386A8K43CM4-CVF)
A single Samsung M386A8K43CM4-CVF LRDIMM delivers 128GB of memory capacity, enabling enterprise servers to reach maximum memory configurations of 2TB per system when fully populated. This load-reduced DIMM is engineered specifically for high-density memory deployments in Intel Xeon Scalable processors, making it the go-to choice for infrastructure teams scaling large compute clusters.
The Samsung DDR4-2933 LRDIMM combines three-dimensional DRAM stacking (3DS technology) with advanced load-reduction buffering to minimize electrical stress on server memory controllers. This architecture allows storage architects and IT procurement teams to maximize per-socket density without sacrificing stability or performance. With full ECC protection, 8Rx4 octal-rank configuration, and JEDEC DDR4 standard compliance, the M386A8K43CM4-CVF delivers proven reliability in mission-critical environments. Operating across 0°C to 85°C, Samsung's LRDIMM maintains consistent 21-21-21 CAS latency performance under enterprise workloads. The 1.2V operating voltage aligns with modern efficiency standards for large-scale data center deployments.
