Samsung 8GB DDR3-1866 1Gx72 ECCREG CL13 Memory Module

The Samsung M393B1G70QH0-CMA is an 8GB DDR3 Registered ECC DIMM built for servers that need dependable data integrity and steady throughput. By running at 1866 Mbps and operating at either 1.5 V or a power-saving 1.35 V, it gives administrators the flexibility to balance performance with energy efficiency.

This module includes an on-board register that buffers clock, command, and control signals. The design reduces electrical load on the memory controller, allowing systems with multiple populated slots to remain stable even under heavy workloads. Error-correcting code adds another layer of protection by detecting and correcting single-bit errors, a feature that helps keep databases, virtual machines, and analytics tasks running without interruption.

With its single-rank x4 layout, the module integrates smoothly into platforms that expect 240-pin RDIMMs and supports configurations with up to two DIMMs per channel. IT teams can drop it into enterprise servers from major vendors, lab workstations, or small business file servers to expand capacity without complicated tuning.

Whether you are scaling a virtual host, fine-tuning a web server cluster, or building out an HPC node, the Samsung M393B1G70QH0-CMA offers a straightforward path to higher memory bandwidth and greater system resilience.
