SK Hynix 64GB DDR5-6400MT/s

Built for modern data centre performance, the SK Hynix HMCG94AHBRA480N 64GB DDR5-6400 RDIMM delivers exceptional bandwidth, reliability, and scalability for enterprise-class computing environments. Operating at a high-speed 6400 MT/s (PC5-51200), this module is engineered to support the demanding requirements of next-generation server platforms, including virtualisation, in-memory databases, AI workloads, and high-performance cloud infrastructure. Its 64GB single-module capacity enables dense memory configurations while maintaining efficient power usage at just 1.1V, helping to optimise both performance per watt and overall system efficiency.

Designed with a registered ECC architecture, this module ensures maximum system stability under sustained heavy workloads. The RDIMM design reduces electrical load on the memory controller, enabling improved signal integrity and allowing large-scale multi-module configurations across multi-channel server platforms. Built on a 2Rx4 dual-rank configuration, it offers a strong balance of bandwidth and latency efficiency, while onboard ECC error correction provides continuous data integrity protection—critical for mission-critical environments where uptime and accuracy are essential.

The HMCG94AHBRA480N is fully intended for enterprise server and workstation platforms supporting DDR5 RDIMM memory, including modern Intel Xeon Scalable and AMD EPYC systems. It is not compatible with consumer desktop motherboards, ensuring it remains focused on environments where stability, scalability, and sustained throughput are paramount. Whether deployed in hyperscale data centres or high-density enterprise servers, this SK Hynix module provides a dependable foundation for memory-intensive workloads and future-proof system expansion.
