Samsung 16GB DDR4 2666 Mbps SDRAM Memory Module

The Samsung M393A2K40BB2-CTD is a 16 GB DDR4 registered memory module built for servers that run demanding workloads around the clock. It follows the RDIMM standard, so it drops straight into motherboards that accept registered DIMMs and need error correction for mission-critical data.

Running at 2666 Mbps while using just 1.2 V, the module delivers solid bandwidth without adding extra strain to the power budget of a rack or tower chassis. The 288-pin layout and 1 rank x 4 organization allow straightforward installation and predictable thermal behavior, which is important when modules sit shoulder-to-shoulder in dense systems.

A built-in register cleans up clock, command, and control signals before they reach the DRAM chips, helping large multiprocessor boards stay synchronized even under heavy traffic. The added 8-bit parity enables ECC, so bit-level errors are detected and corrected on the fly. Database servers, hyper-converged nodes, and virtual machine hosts all benefit from this layer of protection because corrupted data never reaches the operating system.

Administrators who manage virtualization clusters, analytics engines, or file servers can slide this module into existing DDR4-2666 platforms to boost capacity without introducing compatibility issues. Whether the environment is a compact edge appliance or a full rack in a data center, the Samsung M393A2K40BB2-CTD helps keep services responsive and reliable while maintaining a controlled power profile.
