Product Overview
The SK Hynix HMAA8GL7AMR4N-UH is a high-density 64GB DDR4 Load Reduced DIMM (LRDIMM) engineered for enterprise server and workstation environments. Operating at 2400MHz (PC4-19200) with a Quad Rank (4DRx4) x4 architecture, this module delivers outstanding memory bandwidth and capacity for demanding workloads including virtualization, large-scale database management, and high-performance computing. The ECC (Error Correcting Code) functionality ensures data integrity and system stability, while the LRDIMM design reduces electrical load on the memory controller — enabling higher memory density per server without sacrificing reliability. At 1.2V, it also maintains energy efficiency befitting a modern enterprise memory solution.
