M393A2K43BB1-CTD Samsung 1x16GB DDR4 ECC RAM

High-Performance DDR4 RDIMM Server Memory featuring ECC Registered architecture with the M393A2K43BB1-CTD

The M393A2K43BB1-CTD is a 16GB DDR4-2666 ECC Registered DIMM designed to stabilise memory behaviour in modern dual-socket server platforms running mainstream Intel Xeon and AMD EPYC generations that rely on high channel utilisation. By using a register between the memory controller and DRAM devices, the module improves signal integrity and supports predictable scaling as DIMM population increases across channels.

In virtualised clusters and general-purpose compute nodes, the M393A2K43BB1-CTD helps maintain consistent latency and error resilience under mixed workloads. It aligns with JEDEC DDR4-2666 (PC4-21300R) operation at 1.2V and fits standard 288-pin RDIMM slots, enabling straightforward expansion without affecting PCIe generations, storage fabrics, or I/O layouts. This makes it a practical choice when balancing CPU core density, memory bandwidth, and capacity per node for database and application server profiles.

Why Choose the M393A2K43BB1-CTD?

The M393A2K43BB1-CTD delivers an enterprise-friendly density-to-performance ratio in a single 16GB RDIMM, allowing architects to scale memory footprints methodically while preserving platform stability. ECC with registered buffering supports higher DIMM loading, reduces the operational risk of soft errors, and keeps fleet configurations consistent for large-scale deployments and lifecycle-managed spares.

Samsung engineers this RDIMM for data centre continuity, focusing on standards compliance, controlled component qualification, and repeatable behaviour across server BIOS and memory training routines. The result is reliable interoperability with modern rack and blade systems that must meet uptime and serviceability requirements.

Key Applications:

• Server virtualisation hosts
• General-purpose compute nodes
• Database and application servers
