M393A2K40BB2-CTD Samsung 1x16GB DDR4 ECC RAM

Enterprise DDR4 RDIMM Memory Module for Reliable Capacity Scaling with the M393A2K40BB2-CTD

The M393A2K40BB2-CTD is a Samsung 16GB DDR4-2666 ECC Registered RDIMM designed for predictable memory expansion in standard DDR4 server platforms. As a JEDEC-compliant 288-pin DIMM, it aligns with OEM-qualified memory rules for mainstream CPU generations that depend on stable channel population, consistent timings, and registered signal integrity at scale.

In multi-socket architectures, the M393A2K40BB2-CTD supports balanced DIMM-per-channel configurations to sustain bandwidth for virtualization, general-purpose compute, and database tiers without introducing non-standard profiles. ECC with a 72-bit data path and a single-rank x4 organization improves fault tolerance and supports enterprise RAS expectations, while 1.2V operation helps keep power and thermals within data centre envelopes. By stabilizing memory behavior, the M393A2K40BB2-CTD enables efficient utilization of PCIe expansion and storage I/O paths by reducing memory-induced contention under mixed workloads.

Why Choose the M393A2K40BB2-CTD?

The M393A2K40BB2-CTD is selected to standardize RDIMM population across fleets where density-to-performance must remain consistent over time. Its registered design improves electrical loading for higher-capacity configurations, supporting scalable deployment from single-server upgrades to rack-level rollouts while maintaining operational reliability and controlled interoperability risk.

Samsung memory engineering focuses on JEDEC adherence, process consistency, and qualification discipline suited to 24/7 enterprise duty cycles. The module’s low-profile form factor supports dense server layouts and airflow requirements common in modern data centre standards.
