About the Samsung 128GB DDR5 6400 ECC Registered DIMM Server Memory
As a 288-pin DIMM module, the Samsung 128GB DDR5 6400 ECC Registered DIMM Server Memory (part number M321RAJA0MB2-CCP) is engineered for direct installation into RDIMM-compatible server motherboards, ensuring proper physical fit before performance considerations come into play. This Samsung memory module delivers enterprise-grade reliability through dual-layer error correction—combining on-die ECC with DIMM-level ECC protection—making it ideal for mission-critical workloads where data integrity cannot be compromised. The quad-rank (4Rx4) configuration maximizes memory density while maintaining stability across demanding virtualization, database, and analytics environments.
Built on Samsung's advanced 1b-nm DRAM process node, this DDR5 module operates at an effective speed of 6400 MT/s with a CAS latency of CL46 and runs at just 1.1V, reducing power consumption without sacrificing performance. For storage architects and IT procurement teams evaluating next-generation server platforms, this module is explicitly validated for Intel Xeon Scalable (Sapphire Rapids+) and AMD EPYC (Genoa+) processors, ensuring seamless integration into the latest data center infrastructures. The 72-bit data width (64-bit data plus 8-bit ECC) and strict JEDEC DDR5 RDIMM standard compliance guarantee compatibility and long-term support across multi-vendor environments. Operating reliably between 0°C and 85°C, the M321RAJA0MB2-CCP is built to sustain continuous high-performance computing demands. Whether you are scaling memory capacity for HPC clusters, consolidating virtualized workloads, or architecting resilient storage solutions, this Samsung DDR5 module provides the capacity, speed, and protection your enterprise requires.
