About the SK Hynix 128GB DDR5 4800MT/s RDIMM Memory
SK Hynix 128GB DDR5 4800MT/s RDIMM (HMCT04MEERA129N) is a 4-rank registered DIMM engineered for next-generation Intel Xeon Scalable and AMD EPYC server platforms requiring high-capacity memory with native on-die ECC protection. This enterprise-grade module combines 128GB capacity with DDR5 speed, delivering the performance density that infrastructure architects and data center procurement teams demand for mission-critical deployments.
The HMCT04MEERA129N operates at 1.1V with CAS latency 40 and achieves PC5-38400 performance across DDR5-capable Sapphire Rapids and Genoa platforms. SK Hynix's ODECC (on-die error correction) meets JEDEC DDR5 specifications, ensuring fault tolerance without requiring additional hardware overhead. The low-profile 288-pin form factor maintains 1U-compatible cabinet density while the registering clock driver (RCD) isolates address/command load for improved signal integrity across high-capacity configurations. Built to commercial/server standards (0–85°C operating range), this module supports the demanding workloads that define modern enterprise infrastructure.
Typical Enterprise Deployment Scenarios
- High-Performance Computing (HPC): Accelerate simulation, modeling, and scientific computing tasks requiring 1TB+ total memory per node.
- Database & Data Warehouse: In-memory analytics on large datasets—Snowflake, SAP HANA, and PostgreSQL benefit from 128GB capacity per socket.
- Virtualization Clusters: VMware vSphere and KVM environments hosting hundreds of guest instances with guaranteed memory availability.
- AI/ML Training Infrastructure: Support dense GPU-accelerated workloads where memory bandwidth and ECC reliability prevent training corruption.
- Real-Time Analytics: Finance, telemetry, and streaming platforms where sub-millisecond latency and error correction are non-negotiable.
