About the Samsung 64GB DDR4 LRDIMM M386A8K40CM2-CWD
Samsung DDR4-2933 64GB LRDIMM (M386A8K40CM2-CWD) delivers 23,400 MB/s bandwidth in a quad-rank, load-reduced form factor engineered for high-density server deployments. This Samsung module combines capacity with thermal efficiency, featuring low-profile construction (31.25 mm) and full ECC support for mission-critical infrastructure requiring robust error detection and correction.
The M386A8K40CM2-CWD is optimized for Intel Xeon Scalable processors (Cascade Lake, Cooper Lake generation) and meets JEDEC DDR4 LRDIMM standards. With CAS latency 21 and 1.2V operation across the 0–85°C range, this Samsung module reduces memory subsystem strain in high-core-count systems where conventional RDIMMs create excessive electrical load. Infrastructure architects and storage teams sourcing memory for virtualized environments, database clusters, or HPC workloads will find the quad-rank configuration essential for maximizing DIMM slot utilization. The C-die (CWD) revision ensures proven compatibility and reliability across enterprise deployments. RoHS compliant and field-tested in data center operations, this part number is available through Omnixon Global for integration into your enterprise platform roadmap.
Enterprise Deployment Scenarios
- High-density virtualization platforms requiring 2TB+ memory per chassis with reduced slot count
- In-memory database systems (SAP HANA, Oracle Exadata) demanding ECC protection and consistent performance
- Analytics and big-data clusters where load-reduction prevents memory controller saturation
- Large-scale backup and archive appliances running across distributed server nodes
- Mission-critical transactional workloads needing multi-bit error detection on every memory access
