About the SK Hynix 256GB DDR5-4800 LRDIMM Server Memory
A single SK Hynix 256GB DDR5-4800 LRDIMM module unlocks memory ceiling of 256GB per slot, enabling enterprise data centers to achieve multi-terabyte system configurations essential for scale-out computing. The HMCG98MEBRA145N (SK Hynix manufacturer part number) delivers 4800 MT/s throughput at just 1.1V, combining density with thermal efficiency across next-generation server platforms. This 288-pin LRDIMM uses load-reduced architecture with integrated Registering Clock Driver (RCD) and Data Buffer (DB) components, distributing electrical load to support high-capacity multi-socket deployments without sacrificing stability or lifespan.
SK Hynix engineered dual-layer error correction—both On-Die ECC and Host ECC—into the 8Rx4 rank configuration, critical for mission-critical workloads where data integrity cannot be compromised. The module operates across 0°C to 85°C, meeting enterprise environmental standards for both air-cooled and liquid-cooled infrastructure. Compatible with Intel Xeon Scalable (Sapphire Rapids+) and AMD EPYC (Genoa+) processors, this DDR5 LRDIMM addresses the technical procurement needs of storage architects and IT procurement teams modernizing high-performance server environments.
