M386B4G70DM0-CMA Samsung 1x32GB DDR3 RDIMM ECC RAM

High-Density DDR3 LRDIMM Server Memory Expansion with the M386B4G70DM0-CMA

The M386B4G70DM0-CMA is a 32GB DDR3 LRDIMM designed for enterprise platforms that require higher per-socket capacity on 240-pin DDR3 memory channels while maintaining signal integrity under heavy DIMM loading. As a load-reduced ECC module, it offloads command/address buffering to enable stable population across multi-channel CPU architectures common in legacy virtualization and scale-up nodes.

With JEDEC-aligned 1866 MT/s operation and 72-bit ECC data paths, the M386B4G70DM0-CMA supports predictable latency behavior for mixed VM and database profiles where memory pressure drives paging and throughput loss. In systems constrained by PCIe expansion or storage bandwidth, increasing DRAM headroom is often the most effective architectural lever: the M386B4G70DM0-CMA helps keep working sets resident, reducing storage I/O amplification and improving overall platform efficiency without changing CPU generation, PCIe topology, or drive architecture.

Why Choose the M386B4G70DM0-CMA?

The M386B4G70DM0-CMA provides an enterprise-focused capacity and reliability profile for DDR3 RDIMM/LRDIMM-capable servers, prioritizing density per slot and stable operation at scale. By enabling higher DIMM population levels compared to standard registered modules, the M386B4G70DM0-CMA supports consistent performance in consolidated environments and offers a pragmatic upgrade path for extending the service life of validated DDR3 infrastructure.

Samsung designs server memory with a disciplined focus on JEDEC compliance, rigorous qualification, and long-term supply consistency, aligning with data centre requirements for predictable interoperability, controlled change management, and dependable error correction behavior in 24/7 operations.
