Samsung M393A2K43DB2-CTD6Y 16GB DDR4-2666MHz RDIMM 2Rx8 CL19 Memory

Product Description

The Samsung M393A2K43DB2-CTD6Y is a 16GB DDR4 Registered DIMM (RDIMM) memory module, engineered for high-performance server and workstation environments. It operates at a rapid speed of 2666MHz, corresponding to the PC4-21300 specification, delivering substantial bandwidth for demanding computing tasks. The RDIMM design incorporates an onboard register that buffers command and address signals, reducing the electrical load on the memory controller. This allows for greater system stability and the ability to support higher memory capacities, making it ideal for memory-intensive applications. This module features a 2Rx8 organization, signifying it is dual-ranked with eight memory chips per rank. Dual-rank configurations can sometimes provide performance benefits by enabling the memory controller to interleave accesses between ranks. With a CAS Latency (CL) of 19, it offers a standard timing for DDR4 memory at this speed, balancing responsiveness with system stability. The standard operating voltage for DDR4 is 1.2V, which contributes to improved power efficiency and thermal management in server deployments. As an ECC (Error-Correcting Code) memory module, the M393A2K43DB2-CTD6Y provides enhanced data integrity by detecting and correcting common types of internal data corruption. This capability is crucial for mission-critical server applications where data accuracy and continuous operation are essential. The 288-pin connector is standard for DDR4 DIMM slots, ensuring compatibility with appropriate server and workstation motherboards. This Samsung RDIMM is a reliable component for upgrading or building systems that require robust, error-corrected memory with high capacity and speed.
