Product Description
The Samsung M391A4G43MB1-CTD0Q is a high-capacity 32GB DDR4 Unbuffered DIMM (UDIMM) memory module. This module is designed for systems that can accommodate larger memory footprints, such as high-end desktops, workstations, and some entry-level servers that utilize UDIMMs. DDR4 technology offers improved performance and power efficiency compared to previous generations, and the 2666MHz speed (PC4-21300) provides substantial bandwidth for demanding applications. This module features a 2Rx8 configuration, indicating it is dual-rank with x8 memory chips. Dual-rank modules can sometimes offer performance advantages by allowing the memory controller to access data from different ranks, potentially improving efficiency in certain workloads. The CAS Latency (CL) is 19, which is a standard timing for DDR4 memory at this speed, representing the delay in clock cycles before data is available. As a non-ECC (Error-Correcting Code) memory module, it does not include error correction capabilities. This makes it suitable for standard computing tasks where the highest level of data integrity is not a primary concern, or where the system's motherboard does not support ECC memory. The 32GB capacity makes this Samsung UDIMM an excellent choice for users running memory-intensive applications like video editing, 3D rendering, large-scale data analysis, or extensive multitasking.
