About the SK Hynix 64GB DDR5 6400MHz 2Rx4 RDIMM ECC Memory Module HMCG94BHBRA276N
SK Hynix 64GB DDR5 RDIMM with ECC is a dual-rank, x4 registered DIMM engineered for mission-critical server deployments on Intel Xeon Scalable (Sapphire Rapids+) and AMD EPYC (Genoa+) platforms. The HMCG94BHBRA276N module delivers 64GB capacity at 6400 MT/s (PC5-51200 rating) with native on-die ECC and integrated thermal sensing per JEDEC DDR5 RDIMM specification. Operating at 1.1V with a 288-pin interface and standard height form factor, this SK Hynix memory combines density, reliability, and performance in a footprint designed for enterprise-scale infrastructure.
Enterprise storage architects, data center IT procurement teams, and infrastructure engineers standardize on this module when deploying high-availability systems that demand error correction and registered DIMM stability. The 2Rx4 rank configuration balances capacity per slot with signal integrity, while on-die ECC eliminates single-bit corruption silently—critical for databases, virtualization platforms, and analytics workloads running 24/7. SK Hynix's manufacturing heritage ensures consistent quality and long-term availability, making HMCG94BHBRA276N a trusted choice for organizations building out next-generation Xeon and EPYC server fleets.
