Product Description
The Samsung M393A2G40EB2-CTDTQ is a 16GB DDR4 Registered DIMM (RDIMM) module, designed to meet the memory demands of server and workstation environments. Its 2Rx4 configuration indicates two ranks of memory chips, each containing four banks, which helps in optimizing data throughput and efficiency within the system's memory controller. This configuration is suitable for a broad range of server applications, including virtualization, database management, and general-purpose computing. Operating at a frequency of 2666MHz, this module provides a solid performance level for multitasking and running memory-intensive applications. The CAS Latency (CL) of 19 is a common specification for DDR4 memory at this speed, ensuring timely data retrieval. As a Registered DIMM, it incorporates an onboard register that buffers address and command signals, reducing the electrical load on the memory controller. This feature is essential for enabling higher memory capacities and maintaining signal integrity in systems populated with multiple memory modules. This memory module also features Error-Correcting Code (ECC) functionality, which is critical for server environments where data accuracy and system stability are paramount. ECC detects and corrects single-bit errors, preventing data corruption and system crashes. The module adheres to standard DDR4 specifications, ensuring compatibility with servers and workstations that support DDR4 RDIMMs, providing a reliable and efficient memory upgrade or replacement solution.
