Samsung DDR4-2666 128GB LRDIMM memory module delivers enterprise-grade capacity and speed for mission-critical server deployments. The M386AAG40BM3-CTD combines 128GB per module with 2666 MT/s performance, enabling data centers to scale memory-intensive workloads without architectural compromise.
Built on Samsung's proven 3DS TSV architecture, this LRDIMM features eight ranks with x4 organization, ECC protection, and an isolation memory buffer (iMB) for load reduction across Intel Xeon Scalable processors. Operating at 1.2V with CAS latency 19, the module maintains stability across enterprise temperature ranges (0–85°C) while adhering to JEDEC DDR4 standards. Infrastructure architects and storage teams consistently specify this part number for hyperscale deployments requiring maximum memory density per socket. Samsung's reputation for reliability makes the M386AAG40BM3-CTD a trusted choice for financial services, healthcare analytics, and research computing environments where data integrity is non-negotiable.
