About the SK Hynix DDR5 16GB 4800 MT/s RDIMM
A single SK Hynix DDR5 16GB module enables server configurations up to 2TB total memory capacity—the ceiling that enterprise infrastructure architects and data center teams require for mission-critical workloads. This RDIMM (Registered DIMM) is purpose-built for fault-tolerant environments where downtime is unacceptable and data integrity is non-negotiable.
The SK Hynix HMAA2GR7AJR8N-XN delivers 4800 MT/s throughput with dual on-die error correction: industry-standard ECC plus DDR5's hardware-level ODECC technology that detects and corrects single-bit errors in real time. Operating at just 1.1V, this memory reduces power consumption versus previous generations while maintaining compatibility with Intel Xeon Scalable 4th Gen (Sapphire Rapids) and AMD EPYC 4th Gen (Genoa) platforms. Storage architects, IT procurement teams, and HPC infrastructure engineers specify SK Hynix DDR5 RDIMMs to maximize reliability and uptime across hyperscale data centers, financial services clusters, and AI inference deployments. The 2Rx8 dual-rank organization and registered clock driver (RCD) architecture ensure signal integrity at scale, critical for densely populated server chassis.
