About the SK Hynix 64GB DDR5-4800MHz 2Rx4 ECC
SK Hynix 64GB DDR5-4800 MHz 2Rx4 ECC RDIMM delivers enterprise-grade memory performance at 4800 MT/s with full error correction for mission-critical server deployments. This JEDEC-standard registered DIMM (part number HMCG94MEBRA123N) combines high capacity with proven reliability, making it the foundation for data centers, virtualization clusters, and large-scale database environments.
The SK Hynix module features dual-rank (2Rx4) architecture with on-die ECC (ODECC) and registered error correction, eliminating silent data corruption in demanding workloads. Operating at just 1.1V with CAS latency of CL40 (timing 40-39-39), it maintains thermal stability across the full 0–85°C operating range while supporting Post Package Repair (PPR) for extended module longevity. The 288-pin form factor integrates seamlessly into existing enterprise infrastructure without compatibility concerns. SK Hynix manufacturing ensures consistent quality and supply chain stability—critical factors for organizations scaling infrastructure across multiple sites.
Storage architects, IT procurement teams, and infrastructure engineers standardize on this configuration for Xeon-based servers, hyperconverged systems, and high-memory analytics platforms where downtime and data integrity carry significant costs. Whether you're refreshing aging DDR4 environments or building new DDR5 capacity, the HMCG94MEBRA123N strikes the right balance between performance, protection, and total cost of ownership.
