M386B4G70DM0-YK0 Samsung 1x32GB DDR3L LRDIMM ECC RAM

High-Density DDR3L ECC LRDIMM Server Memory Expansion featuring quad-rank reliability with the M386B4G70DM0-YK0

The M386B4G70DM0-YK0 is a 32GB DDR3L ECC LRDIMM designed for DDR3-era x86 server platforms that require higher per-slot capacity without increasing power and thermal load. By using a load-reduced architecture, the M386B4G70DM0-YK0 decreases electrical loading on the memory controller to help sustain stable population at scale in multi-DIMM configurations, supporting predictable performance on supported Intel Xeon E5/E7 and comparable enterprise platforms.

Operating at DDR3-1600 (PC3L-12800L) with JEDEC timing, the M386B4G70DM0-YK0 targets balanced throughput and latency characteristics for virtualization clusters, enterprise application stacks, and memory-constrained legacy nodes. Its quad-rank 72-bit ECC design focuses on data integrity and uptime, while the 1.35V DDR3L profile improves efficiency across dense deployments. The low-profile 240-pin DIMM format supports space-restricted server layouts and maintains airflow planning in 1U/2U chassis where thermals and serviceability are critical.

Why Choose the M386B4G70DM0-YK0?

The M386B4G70DM0-YK0 delivers a pragmatic capacity uplift for DDR3L servers by maximizing gigabytes per socket within existing PCIe and storage architectures, avoiding disruptive platform refresh cycles. Its LRDIMM signaling characteristics are engineered for scalable memory footprints, enabling higher consolidation ratios and more consistent performance under mixed workloads while maintaining enterprise-grade reliability expectations.

Samsung designs server DRAM for long lifecycle stability, tight process control, and validation aligned with datacenter operational standards. The focus is on predictable interoperability, consistent electrical characteristics, and sustained availability for enterprise maintenance windows and controlled change management.
