About the Samsung 64GB DDR5 Registered ECC Memory
Intel Xeon Scalable (Sapphire Rapids and later) and AMD EPYC Gen 4 (Genoa/Bergamo) systems demand memory modules engineered for mission-critical reliability, and Samsung's 64GB DDR5 Registered ECC Memory delivers exactly that specification. The Samsung M321R8GA0PB0-CWMXJ is a 288-pin RDIMM built for enterprise data centers where error correction and fault tolerance are non-negotiable. Operating at DDR5-4800 (PC5-38400) with a 4800 MT/s data transfer rate, this dual-rank module combines high throughput with the robust error detection and correction needed in virtualization, database, and AI workload environments.
Samsung engineered this module with integrated PMIC on-die power management and Error Correcting Code (ECC) with on-die ECC (ODECC) to protect against single-bit errors in real time. The 64GB capacity in a 2Rx4 configuration with CAS Latency CL40 and primary timings of 40-39-39 provides the balance of performance and stability that storage architects and IT procurement teams expect in Xeon Scalable and EPYC platforms. Operating at 1.1V with a temperature range of 0°C to 85°C and full RoHS compliance, the M321R8GA0PB0-CWMXJ integrates seamlessly into modern hyperscale and edge deployments.
