About the Samsung 128GB DDR5-6400 RDIMM Server Memory
Samsung DDR5-6400 at 128GB capacity delivers enterprise-class memory speed and density for next-generation server architectures. The Samsung M329R0GA0PB0-CQK is a 128GB DDR5 RDIMM module engineered for high-performance, mission-critical computing environments. Operating at 6400 MT/s with a PC5-51200 speed rating, this registered DIMM combines raw throughput with industry-leading reliability. Built on a 288-pin architecture with 2Rx4 rank configuration and a 72-bit data width (64-bit base plus ECC), the module delivers both protection and performance across demanding workloads. Samsung has designed this memory with on-die error correction (ODECC) and full ECC support, critical for systems where data integrity cannot be compromised. The low-profile form factor ensures compatibility with LRDIMM-capable server slots, while 1.1V operation and an operating temperature range of 0°C to 85°C reflect enterprise thermal and power efficiency standards. RoHS compliance underscores Samsung's commitment to environmental responsibility.
Data center architects, network infrastructure teams, and IT procurement departments select this Samsung RDIMM for Intel Xeon Scalable processors (Sapphire Rapids and later) and AMD EPYC platforms (Genoa and later) where DDR5 RDIMM support is essential. Organizations running virtualization, cloud computing, in-memory analytics, and high-frequency trading systems depend on the CL52 latency and 128GB single-module capacity to minimize system complexity while maximizing memory density per socket. The combination of speed, capacity, and error correction makes this module indispensable for environments that cannot tolerate unplanned downtime or data corruption.
