About the Samsung 128GB DDR4 LRDIMM M386AAG40EM3-CRC
CL17 at 1.2V — the Samsung M386AAG40EM3-CRC delivers predictable latency for latency-sensitive workloads, from high-frequency trading platforms to in-memory databases that demand sub-microsecond response times. This 128GB DDR4 LRDIMM operates at 2400 MT/s (PC4-19200) with full ECC protection, making it the standard choice for mission-critical enterprise servers where data integrity cannot be compromised. The octal rank (8Rx4) configuration and load-reduced design enable maximum memory density per socket on Intel Xeon Scalable (Purley-generation) platforms, reducing overall server footprint while scaling storage capacity across large clusters.
Samsung's M386AAG40EM3-CRC is engineered for infrastructure teams managing virtualization farms, database clusters, and consolidated workloads that require both capacity and reliability. The 288-pin LRDIMM form factor distributes electrical load across ranks, extending system stability and lifespan in 24/7 production environments. Operating across 0–85°C, this module handles demanding thermal conditions in dense data centre racks. Storage architects and IT procurement teams standardize on this part number for predictable performance across multiple server generations.

Typical Enterprise Deployment Scenarios
- Consolidation of large SAP, Oracle, and PostgreSQL databases on shared server pools
- Hypervisor memory pools for VMware vSphere and Hyper-V environments scaling beyond 2TB per host
- Real-time analytics and BI platforms requiring sub-second query latency across terabyte datasets
- High-throughput financial and market-data platforms where CAS latency directly impacts transaction throughput
- Disaster-recovery and failover clusters where ECC detection and single-bit correction prevent cascade failures
