SK Hynix HMAA8GL7MMR4N-UH 64GB DDR4 2400MHz 4Rx4 LRDIMM ECC Server RAM (PC4-2400T) Refurbished

SK Hynix HMAA8GL7MMR4N-UH is a 64GB DDR4 2400MHz ECC Load Reduced DIMM (LRDIMM) server memory module built for enterprise and data center environments. Featuring a 4Rx4 quad-rank configuration and PC4-2400T performance class at 1.2V, it delivers high memory density, strong stability, and reliable error correction for mission-critical workloads.

Pulled from working systems, tested and functional.

Key Features

• Model: SK Hynix HMAA8GL7MMR4N-UH — 64GB DDR4 2400MHz (PC4-2400T) ECC LRDIMM
• Load Reduced Architecture: The onboard memory buffer reduces electrical load on the memory controller, allowing higher total capacity and more populated ranks per channel than an equivalent registered module.
• High Density Support: The 4Rx4 quad-rank configuration places four ranks of x4 DRAM on a single 288-pin module, delivering 64GB per slot for high-density enterprise deployments.
• Data Integrity: Integrated ECC (Error-Correcting Code) functionality helps detect and correct memory errors in real time, ensuring improved system reliability and uptime for mission-critical workloads in data center environments.
• Enterprise-Grade Design: Engineered specifically for server and workstation platforms requiring dependable high-capacity memory. Not compatible with consumer desktops or laptops due to LRDIMM architecture and ECC requirements.
• Compatibility: Supports enterprise platforms using standard 288-pin DDR4 LRDIMM memory slots that specifically support 64GB quad-rank load reduced modules. LRDIMM support is not implied by RDIMM support — verify against your platform's memory QVL and population rules.
• Note: You cannot mix LRDIMMs with RDIMMs or UDIMMs in the same system — ensure all installed modules are of the same type.
