Product Description
The Samsung M391A2K43DB1-CWEQY is a 16GB DDR4 Unbuffered DIMM (UDIMM) memory module, designed for mainstream desktop computers and workstations. This module operates at a speed of 3200MHz, identified by the PC4-25600 standard, offering a significant boost in data transfer rates compared to older DDR generations. The UDIMM form factor is standard for non-server motherboards, providing broad compatibility with a wide range of consumer and prosumer systems. It features a CAS Latency (CL) of 22, which is a key timing parameter affecting memory performance. Unlike Registered DIMMs (RDIMMs) used in servers, UDIMMs are unbuffered, meaning they connect directly to the memory controller without an intermediate register. This makes them generally more cost-effective and suitable for systems where the memory controller can handle the direct load. This particular module is non-ECC, meaning it does not include error-correcting capabilities, which is typical for standard desktop applications where the highest levels of data integrity are not as critical as in server environments. The 2Rx8 organization signifies a dual-rank configuration with an x8 data width per DRAM chip. With its 16GB capacity and DDR4-3200MHz performance, the Samsung M391A2K43DB1-CWEQY is an excellent choice for users looking to upgrade their system's memory for improved multitasking, faster application loading, and smoother overall performance. It is well-suited for gaming, content creation, and general productivity tasks, providing a reliable and efficient memory upgrade path for compatible systems.
