About the SK Hynix 64GB DDR5 LRDIMM
SK Hynix DDR5-4800 64GB LRDIMM — next-generation memory for mission-critical server infrastructure. The HMAA8GR7MJR4N-XN delivers 4800MT/s performance in a 64GB load-reduced DIMM configuration, engineered for demanding enterprise environments where capacity and reliability intersect. This quad-rank (4Rx4), 288-pin module operates at just 1.1V, combining power efficiency with exceptional density on Intel Xeon Scalable 4th Gen (Sapphire Rapids) platforms and compatible DDR5 LRDIMM server architectures.
SK Hynix built this LRDIMM with on-die ECC, integrated data buffers, and low-profile form factor (31.25mm) to minimize thermal overhead while maximizing fault tolerance. The 16Gb DRAM die density and CAS Latency 40 specification provide balanced performance for virtualization, in-memory databases, and high-frequency trading applications. Built-in SPD ensures plug-and-play compatibility, and full JEDEC DDR5 standard compliance guarantees longevity across future hardware refresh cycles. Operating across 0–85°C, the module handles rack-dense deployments without performance degradation.
Data center architects, storage engineers, and IT procurement teams standardizing on DDR5 infrastructure select SK Hynix modules for their proven reliability and cost-per-GB advantage in bulk deployments. Whether you're scaling hyperscale cloud environments, consolidating legacy systems, or architecting next-generation AI inference clusters, the HMAA8GR7MJR4N-XN addresses the capacity and speed demands of modern workloads. Omnixon Global supplies this module direct from verified inventory, backed by technical support across the GCC region.
