About the SK Hynix DDR5 512GB 4800 MT/s LRDIMM
The SK Hynix HMAF64GR7MJR4N-XN is a 512GB DDR5 4800 MT/s LRDIMM engineered for Intel Xeon Scalable and AMD EPYC systems requiring massive memory capacity per socket. This 288-pin, 8-rank module delivers PC5-38400 performance with native CAS Latency 40, operating at just 1.1V to minimize thermal load and power consumption in high-density server environments. SK Hynix built this module with load-reduction architecture—featuring an on-board Registering Clock Driver (RCD) and Data Buffer (DB)—to maximize channel stability across 12+ DIMM configurations typical in modern data center deployments.
Data center architects, storage engineers, and AI infrastructure teams specify SK Hynix DDR5 LRDIMMs like this for mission-critical workloads demanding both capacity and reliability. The dual-layer error correction—system-level ECC combined with on-die ECC (ODECC)—ensures enterprise-grade fault tolerance, while JEDEC DDR5 LRDIMM compliance guarantees interoperability with certified platforms. Organizations building high-memory-footprint clusters for analytics, machine learning model training, and virtualization environments depend on SK Hynix's proven DRAM reliability. The module's wide operating temperature range (0°C to 85°C) and RoHS compliance meet stringent procurement standards in regulated industries.
