About the SK Hynix 128GB DDR5 LRDIMM
The SK Hynix 128GB DDR5 LRDIMM (HMAF16GR7MJR4N-XN) is an 8Rx4 Load-Reduced module engineered for high-density server environments requiring enterprise-grade reliability. This DDR5 LRDIMM combines on-die ECC with module-level error correction, delivering dual-layer data protection across 72-bit architecture—ideal for mission-critical infrastructure where data integrity is non-negotiable. Storage architects and AI infrastructure teams designing next-generation data centers will appreciate the integrated Power Management Integrated Circuit (PMIC) and SPD Hub, which simplify platform provisioning while reducing thermal load across dense server racks.
SK Hynix's DDR5 LRDIMM specification includes advanced RAS (Reliability, Availability, Serviceability) features such as command/address parity, on-module temperature sensing, and JEDEC-compliant DDR5 standards. Operating at 1.1V with thermal resilience across 0°C to 85°C, this module supports seamless integration into major OEM server platforms supporting Load-Reduced form factors. The low-profile design maximizes memory density without compromising airflow or system stability. Whether scaling hyperscale deployments, financial databases, or HPC clusters, the SK Hynix HMAF16GR7MJR4N-XN delivers 128GB capacity in a single DIMM slot, reducing server sprawl and operational complexity.
