The Samsung 64GB DDR4 RDIMM (M393A8K43DB4-CVF) is a quad-rank registered ECC module engineered for Intel Xeon Scalable and AMD EPYC platforms. This enterprise-grade memory delivers 2933 MT/s performance at PC4-23400 specification with CAS latency 21, combining reliability with throughput for mission-critical server environments. The module features Samsung's advanced 3D TSV technology, enabling higher density within a standard 288-pin DIMM form factor while maintaining strict JEDEC DDR4 compliance and operating stability across 0°C to 85°C temperature ranges.
Data center administrators, storage architects, and IT procurement teams select the M393A8K43DB4-CVF for virtualized infrastructure, database servers, and high-performance computing workloads where error correction is non-negotiable. The integrated ECC protection safeguards against single-bit failures that could compromise uptime or data integrity. Samsung's reputation for manufacturing quality ensures consistent performance across large-scale deployments, making this RDIMM a trusted choice for organizations standardizing on Xeon Scalable or EPYC-based systems. The quad-rank configuration optimizes memory density per slot, reducing total module count while supporting 1.2V low-voltage operation for improved power efficiency in multi-socket server builds.
Whether you are refreshing existing infrastructure or scaling new deployments, our technical team can validate compatibility with your specific platform requirements.
