Samsung M393A1G40EB2-CTD7Q 8GB DDR4-2666MHz RDIMM 1Rx4 CL19 Memory

Product Description

The Samsung M393A1G40EB2-CTD7Q is an 8GB DDR4 Registered DIMM (RDIMM) module, engineered for server and workstation applications where reliability and performance are paramount. It operates at a higher frequency of 2666MHz, offering improved bandwidth compared to lower-speed DDR4 modules. The 1Rx4 configuration signifies a single-rank design with four data bits per chip, which is common for modules of this capacity and provides efficient memory access for many server workloads. As an RDIMM, this module includes an onboard register that buffers command and address signals, reducing the load on the memory controller. This feature is essential for enabling higher memory densities and maintaining signal integrity in systems with multiple memory channels. The CAS Latency (CL) of 19 is a key timing parameter that dictates the delay between the memory controller requesting data and the data being available. While CL19 is slightly higher than some lower-speed modules, it is appropriate for the 2666MHz frequency, offering a balanced performance profile. This 8GB DDR4 RDIMM also supports ECC (Error-Correcting Code) functionality, which is a critical feature for server environments to detect and correct memory errors, thereby preventing data corruption and system crashes. Operating at the standard 1.2V for DDR4, it ensures compatibility with a wide range of server platforms. This module is a suitable choice for memory upgrades or for building systems that require dependable, error-corrected memory with a moderate capacity and good performance.
