The M386AAG40DM3-CWE is the trusted high-density memory solution for Intel Xeon Scalable server platforms requiring maximum per-slot capacity and rock-solid ECC-backed reliability.

Key Features & Performance Benefits

•   128GB Per-Slot Maximum Memory Density: Provides the highest available per-slot memory capacity, enabling denser VM deployments, larger in-memory databases, and more expansive AI/ML working datasets per server.
•   DDR4-3200 PC4-25600 High-Speed Performance: Operates at 3200 MHz with CL22 latency timings for fast, consistent, and low-latency memory access under the heaviest multi-threaded server workloads.
•   ECC Error-Correcting Code Protection: Full ECC memory continuously detects and corrects single-bit memory errors, maintaining system uptime and data integrity in business-critical production environments.
•   Load-Reduced LRDIMM Architecture: Memory buffer reduces electrical load on the memory controller, allowing higher capacity configurations per channel than standard RDIMM modules support.
•   Quad Rank x4 Configuration (4Rx4): Quad Rank x4 organization optimizes per-slot capacity and signal integrity for validated high-density server deployments.
•   Energy-Efficient 1.2V Operation: Low-voltage design minimizes power draw and thermal output per module, supporting sustainable, cost-efficient high-density data center operations.
•   Enterprise Server Platform Certified: Compatible with Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem, Cisco UCS, and Supermicro server platforms supporting DDR4-3200 LRDIMM modules.
•   Samsung Quality Assurance: Built to Samsung’s strict enterprise manufacturing standards for long-term reliability in mission-critical production server deployments.

Best-Fit Applications

•   Enterprise Virtualization Platforms: Maximize virtual machine density per server node in VMware, Hyper-V, and KVM environments.
•   In-Memory Database & Analytics: Support SAP HANA, Redis, and real-time analytics workloads with massive in-memory data pool capacity.
•   AI & Machine Learning Infrastructure: Provide large working memory for model training, inference serving, and data pre-processing pipelines.
•   High-Performance Computing (HPC): Power distributed computing workloads requiring massive memory bandwidth and capacity.
•   Hyperscale Cloud Data Centers: Maximize memory density per rack unit in high-density cloud server infrastructure.
