Product Description
The Samsung M391A1K43DB2-CWEQ is an 8GB DDR4 Unbuffered Dual In-line Memory Module (UDIMM) designed for standard desktop computers and entry-level servers. This module operates at a high frequency of 3200MHz, identified as PC4-25600, and has a CAS Latency (CL) of 22. The 1Rx8 configuration signifies a single-rank module where each rank is composed of 8-bit memory chips, providing a balance of capacity and performance for everyday computing tasks. Unbuffered DIMMs (UDIMMs) do not have a register chip; the memory controller communicates directly with the DRAM chips. This direct communication path generally results in lower latency compared to RDIMMs, making them suitable for applications where responsiveness is key, such as gaming and general productivity. The standard operating voltage for DDR4 UDIMMs is 1.2V, contributing to lower power consumption. This specific Samsung memory module, bearing the part number M391A1K43DB2-CWEQ, is intended for use in systems that support DDR4 memory and do not require ECC (Error-Correcting Code) functionality. It is a common choice for upgrading existing systems or building new PCs and servers that benefit from faster memory speeds and increased capacity for multitasking and demanding applications.
