Samsung M393A2K40CB2-CTD8Q 16GB DDR4-2666MHz RDIMM 1Rx4 CL19 Memory

Product Description

The Samsung M393A2K40CB2-CTD8Q is a high-performance 16GB DDR4 memory module specifically designed for server and workstation environments. As a Registered DIMM (RDIMM), it incorporates an onboard register that buffers command and address signals, reducing the electrical load on the memory controller. This feature is crucial for systems utilizing a large number of memory modules, as it enhances signal integrity and allows for higher memory capacities and speeds to be reliably supported. The RDIMM format also includes Error-Correcting Code (ECC) functionality, which detects and corrects single-bit memory errors, significantly improving system stability and data integrity – a critical requirement for mission-critical applications. This module operates at a DDR4-2666MHz speed, identified as PC4-21300, providing substantial bandwidth for data-intensive tasks. The CAS Latency (CL) is rated at CL19, indicating the number of clock cycles required for the memory to respond to a column address command. The 1Rx4 memory organization signifies that the module is single-ranked and uses a 4-bit-wide data interface per memory chip. This configuration is optimized for performance and compatibility with a wide range of server chipsets and processors that support DDR4 memory technology. With a standard operating voltage of 1.2V, the M393A2K40CB2-CTD8Q adheres to the energy efficiency standards of DDR4 technology. Its combination of high capacity, ECC support, registered buffering, and high speed makes it an ideal choice for upgrading or populating servers and workstations used for virtualization, database management, scientific computing, content creation, and other demanding professional workloads where memory performance and reliability are paramount.
