Description

The Samsung M393A2K40BB2-CTD-DNA is a high-performance 16GB memory module designed for server and workstation environments. It operates at a speed of 2666MHz, providing ample bandwidth for demanding applications and multitasking scenarios. The DDR4 technology ensures improved power efficiency and performance compared to previous generations of RAM. As a Registered DIMM (RDIMM), this module incorporates an onboard register that buffers command and address signals, reducing 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 stability. The 1Rx4 memory organization indicates a single rank with four data bits per chip, optimized for specific memory controller architectures. With a CAS Latency (CL) of 19, this module offers a balance between speed and timing. It also features Error-Correcting Code (ECC) functionality, which detects and corrects single-bit errors, significantly improving system reliability and data integrity. This makes the M393A2K40BB2-CTD-DNA an ideal choice for mission-critical applications where uptime and data accuracy are paramount.
