About the Samsung 256GB DDR5-4800 LRDIMM ECC (Load Reduced)

The Samsung 256GB DDR5-4800 LRDIMM ECC is a load-reduced dual in-line memory module engineered for high-density enterprise server deployments. This module delivers 256GB capacity per DIMM at DDR5-4800 speed (4800 MT/s), enabling significant memory consolidation in 2-socket and multi-socket systems while maintaining full error correction and system stability.

Load-reduced technology distributes electrical load across dedicated register and buffer components, allowing for higher memory density per server without compromising signal integrity or reliability. The ECC (Error-Correcting Code) protection detects and corrects single-bit errors in real time, critical for mission-critical applications where data integrity is non-negotiable.

Optimized for data centers, AI/ML inference platforms, large-scale analytics, and virtualized environments where memory density, thermal efficiency, and uptime are primary considerations. Compatible with 4th Gen Intel Xeon Scalable (Graveltino) and equivalent AMD EPYC platforms requiring registered DDR5 memory.

Ideal for

  • High-density virtualization clusters requiring 10+ TB per-server memory configurations
  • Large language model (LLM) inference and AI workload acceleration with extensive tensor caching
  • In-memory database systems (SAP HANA, Oracle Exadata) demanding multi-terabyte footprints
  • Real-time financial analytics and algorithmic trading platforms with sub-microsecond latency requirements
  • Enterprise data warehouse consolidation and analytical query processing at scale
  • Kubernetes orchestration and containerized microservices with stateful memory-intensive applications
