About the SK Hynix DDR5 64GB 4800 MT/s RDIMM
SK Hynix DDR5 64GB at 4800 MT/s in RDIMM form factor delivers enterprise-grade memory performance for next-generation data center infrastructure.
The HMAA8GR7AJR4N-XN is a registered DIMM engineered for mission-critical server environments requiring maximum reliability and uptime. SK Hynix's on-die ECC combined with module-level error correction ensures data integrity across demanding workloads. With integrated power management and a 10-layer PCB design, this module operates efficiently at just 1.1V, reducing power consumption while maintaining thermal stability from 0°C to 85°C. The 8Rx4 organization and 288-pin configuration provide optimal compatibility with Intel Xeon Scalable (Sapphire Rapids) and AMD EPYC platforms running DDR5-capable architectures. Storage architects, cloud infrastructure teams, and IT procurement specialists typically evaluate SK Hynix RDIMM solutions for virtualization, database servers, and high-performance computing clusters. Registered memory eliminates signal degradation, enabling longer module lifespans and superior scaling across multi-socket systems. The JEDEC DDR5 standard compliance guarantees interoperability and future-proofs your investment against emerging processor generations. RoHS certification confirms environmental compliance for sustainable data center operations.
