Samsung 128GB 4DRx4 LRDIMM- 3200MT/s Load Reduced (M386AAG40AM3-CWE-OSTK)

Maximize your enterprise server’s memory capacity and reliability with the Samsung 128GB DDR4-3200 ECC LRDIMM (M386AAG40AM3-CWE). Engineered specifically for high-density rack-mount servers and mission-critical workloads, this 288-pin Load-Reduced DIMM module delivers DDR4-3200 (PC4-25600) speeds with full ECC error-correction, a Quad Rank x4 configuration, and a low 1.2V operating voltage. Compatible with leading enterprise server platforms from Dell, HPE, Lenovo, and Cisco, it is the definitive choice for data centers requiring maximum per-slot memory density without sacrificing stability or power efficiency.

Key Features & Performance Benefits

•   128GB Per-Slot Maximum Density: A single module provides 128GB of server memory, maximizing per-slot capacity to support more virtual machines, larger in-memory databases, and broader AI/ML datasets per server node.
•   DDR4-3200 PC4-25600 Performance: Operates at 3200 MHz with CL22 latency and PC4-25600 bandwidth for consistently fast, low-latency server memory access during intensive workloads.
•   ECC Error-Correcting Code Technology: Full ECC memory automatically detects and corrects single-bit memory errors in real time, ensuring continuous system stability and data integrity in production environments.
•   Load-Reduced LRDIMM Architecture: The Load-Reduced DIMM architecture uses a memory buffer to reduce the electrical load on the memory controller, enabling higher memory capacity per channel than standard RDIMM configurations.
•   Quad Rank x4 Configuration (4Rx4): Quad Rank x4 organization maximizes memory density and capacity per slot while maintaining electrical compatibility with supported server platforms.
•   Energy-Efficient 1.2V Operation: Low 1.2V supply voltage minimizes power consumption and heat generation per module, reducing cooling requirements and operational costs in high-density server deployments.
•   Broad Server Platform Compatibility: Certified compatible with Intel Xeon Scalable processor-based server platforms from Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem, Cisco UCS, and Supermicro.
•   Samsung Server-Grade Reliability: Manufactured to Samsung’s stringent enterprise-grade quality standards for verified long-term reliability in mission-critical server environments.

Best-Fit Applications

•   Large-Scale Enterprise Virtualization: Maximize VM density per server node with 128GB modules in VMware vSphere, Microsoft Hyper-V, and KVM hypervisor environments.
•   In-Memory Database Servers: Power SAP HANA, Redis, Oracle TimesTen, and other in-memory database workloads requiring maximum available server RAM.
•   AI/ML Training & Inference Infrastructure: Provide large working memory pools for AI model training frameworks and high-throughput inference serving pipelines.
•   Big Data Analytics & High-Performance Computing: Support Apache Spark, Hadoop, and HPC workloads requiring massive in-memory data processing capacity.
•   Cloud & Hyperscale Data Center Servers: Maximize memory capacity per rack unit in high-density hyperscale and cloud data center server deployments.
