About the SK Hynix DDR5 192GB 4800 MT/s RDIMM
Built for Intel Xeon Scalable (Sapphire Rapids and later) and AMD EPYC (Genoa and later) server platforms, the SK Hynix DDR5 192GB 4800 MT/s RDIMM (part number HMAF24GR7AJR4N-XN) delivers enterprise-grade memory capacity and reliability for mission-critical data center workloads. This 4-rank, 288-pin registered DIMM operates at 4800 MT/s (PC5-38400) with CAS latency 40, providing balanced performance across high-density server configurations. The module features dual error correction—system-level ECC plus on-die ECC (ODECC)—ensuring data integrity in virtualization, database, and AI infrastructure environments where uptime is non-negotiable.
SK Hynix's 3DS (three-dimensional stacked) die technology maximizes capacity while maintaining thermal stability across the standard commercial operating range of 0°C to 85°C. At 1.1V operating voltage, the module delivers power efficiency critical for large-scale deployments. Storage architects and IT procurement teams selecting high-capacity DDR5 solutions will find this RDIMM particularly suited to consolidation projects, in-memory analytics, and next-generation hyperscaler builds.
