Product Description
The Samsung M393A2K40BB2-CTD is a high-performance 16GB DDR4 Registered DIMM (RDIMM) memory module, engineered for demanding server and workstation environments. Operating at a speed of 2666MHz (also known as PC4-21300), this module provides substantial bandwidth for data-intensive applications. The RDIMM form factor includes an onboard register that buffers memory commands and addresses, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in multi-module configurations. This module features a 1Rx4 rank organization, meaning it has a single rank with four bits accessed per memory chip. This configuration is often preferred in server applications for its balance of density and performance. With a CAS Latency (CL) of 19, it offers a respectable response time for memory operations. The standard operating voltage for DDR4 is 1.2V, contributing to improved power efficiency compared to previous DDR generations. Crucially, the M393A2K40BB2-CTD incorporates Error-Correcting Code (ECC) functionality. ECC memory can detect and correct common types of internal data corruption, significantly enhancing data integrity and system reliability. This makes it an indispensable component for servers, data centers, and critical workstations where data accuracy and uptime are paramount. Samsung's reputation for quality ensures that this memory module meets stringent performance and reliability standards.
