Product Description
The Samsung M393A2K43BB1-CTD7Y is a high-performance 16GB DDR4 Registered DIMM (RDIMM) memory module, engineered for server and workstation environments. DDR4 technology offers significant improvements in speed, power efficiency, and density over previous generations of RAM. This module operates at a clock speed of 2666MHz, corresponding to a PC4-21300 designation, providing ample bandwidth for demanding applications and multitasking scenarios. The RDIMM form factor includes a register chip that buffers the command and address signals between the memory controller and the DRAM chips. This reduces electrical load on the memory controller, allowing for more memory modules to be installed per channel and improving overall system stability, especially in systems with large memory configurations. The module is also equipped with Error-Correcting Code (ECC) functionality, which detects and corrects single-bit memory errors, crucial for maintaining data integrity in critical server operations. With a 2Rx8 organization, this module consists of two ranks of memory chips, each organized as eight data bits wide. This dual-rank design can sometimes offer performance benefits in certain memory access patterns. The CAS Latency (CL) of 19 indicates the number of clock cycles required to access data after a command is issued. This 16GB DDR4-2666MHz RDIMM is a standard component for modern servers requiring reliable and fast memory performance.
