Product Overview
The SK Hynix HMAA8GL7CPR4N-VK is a high-capacity 64GB DDR4 Load Reduced DIMM (LRDIMM) designed for enterprise servers and data center environments. Operating at DDR4-2666 (PC4-21300) with a Quad Rank x4 (4Rx4) configuration and ECC (Error-Correcting Code) support, this module delivers exceptional memory density, stability, and reliability for demanding workloads including virtualization, database hosting, and high-performance computing. The LRDIMM architecture uses an onboard memory buffer to reduce electrical load on the system's memory controller, enabling higher memory densities per channel than standard RDIMMs. This module is Supermicro certified (MEM-DR464L-HL03-LR26) and compatible with a broad range of Intel-platform servers from Dell, HPE, Lenovo, Cisco UCS, and Supermicro.
