About the SK Hynix DDR5 256GB 6400 MT/s MCRDIMM
SK Hynix DDR5 256GB at 6400 MT/s in MCRDIMM form factor delivers enterprise-grade memory performance for next-generation data centers. The HMCCAGB8MEBRA181N combines massive capacity with high-speed data transfer, purpose-built for Intel Xeon Scalable processors supporting the MCRDIMM specification.
This SK Hynix module is engineered for storage architects, AI infrastructure teams, and data center IT procurement professionals who require reliable, high-density memory for demanding workloads. The DDR5 MCRDIMM architecture features multiplexer combined ranks buffering, enabling maximum modularity and reduced pin load per rank—critical for environments scaling to petabyte-class storage or intensive compute operations. Operating at just 1.1V, the module delivers efficiency gains across large deployments. Dual-layer error correction—combining on-die ECC with DDR5 channel ECC—ensures data integrity in mission-critical systems where downtime is unacceptable. The 288-pin interface and registered buffer design guarantee seamless integration into certified Granite Rapids and compatible platforms.
