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

Product Description

The Samsung M393A2K43DB2-CTD is a 16GB DDR4 Registered DIMM (RDIMM) memory module, designed to deliver high performance and capacity for modern server and workstation systems. Operating at a fast speed of 2666MHz, it provides significant bandwidth, crucial for memory-intensive applications, virtualization, and data analytics. The RDIMM architecture includes an onboard register that buffers command and address signals, reducing the electrical load on the memory controller. This allows for greater stability and the ability to populate systems with more memory modules, enhancing overall system capacity and performance. This module features a 2Rx8 organization, indicating it is dual-ranked with eight memory chips per rank. Dual-rank modules can sometimes offer performance advantages by allowing the memory controller to access data from different ranks concurrently. With a CAS Latency (CL) of 19, it represents a typical timing for DDR4 memory at this speed, balancing responsiveness with stability. The standard operating voltage for DDR4 is 1.2V, contributing to improved power efficiency and thermal management compared to previous DDR generations. As an ECC (Error-Correcting Code) memory module, the M393A2K43DB2-CTD is capable of detecting and correcting common types of internal data corruption. This feature is vital for mission-critical server environments where data integrity and system uptime are paramount. The 288-pin connector is standard for DDR4 DIMM slots, ensuring compatibility with appropriate server and workstation motherboards. This Samsung RDIMM is a reliable choice for upgrading or building systems that require substantial, error-corrected memory.
