M386B4G70DM0-YK04 Samsung 4x8GB DDR3L RDIMM ECC RAM

High-Density DDR3L LRDIMM Server Memory Kit featuring ECC reliability with the M386B4G70DM0-YK04

The M386B4G70DM0-YK04 is a Samsung DDR3L ECC low-profile 240-pin LRDIMM kit engineered to extend the usable lifecycle of DDR3-era server platforms where CPU generation and memory controller limits make validated module selection critical. Deployed as 4x8GB, the M386B4G70DM0-YK04 supports predictable memory population across multi-socket systems, helping maintain stable NUMA layouts for virtualisation and database nodes while preserving compatibility with registered/load-reduced DIMM requirements.

Built for 1600MT/s operation at 1.35V, the M386B4G70DM0-YK04 provides bandwidth aligned to PCIe 3.0 expansion and storage architectures commonly found in legacy enterprise servers, where balanced memory throughput supports RAID/HBA queues, network I/O, and moderate analytics pipelines. Its ECC 72-bit data path and load-reduced architecture improve signal integrity at higher slot counts, enabling scalable capacity growth without forcing platform redesign, and keeping service profiles consistent during phased refresh cycles.

Why Choose the M386B4G70DM0-YK04?

The M386B4G70DM0-YK04 delivers a practical density-to-stability profile for DDR3L infrastructures that must scale memory while protecting uptime. By using LRDIMM electrical loading characteristics and ECC protection, the M386B4G70DM0-YK04 supports higher population schemes with reduced risk of training issues, making it suitable for standardised fleet deployments and controlled maintenance windows.

Samsung memory engineering emphasises validation, consistent component sourcing, and long-run reliability for enterprise environments. The low-profile mechanical format aligns with dense server chassis airflow paths, and the DDR3L power envelope supports data centre efficiency targets without compromising compatibility with established platform standards.

Key Applications:

• Legacy enterprise server memory expansion
• Virtualisation host capacity scaling
• Database buffer and cache growth
• General-purpose compute on DDR3L platforms
• Lab, staging, and platform validation builds
