Product Description
The Samsung M391A1G43EB1-CPBQ is an 8GB DDR4 Unbuffered DIMM (UDIMM) memory module, designed for standard servers and desktop computers. Operating at a speed of 2133MHz, it provides a solid foundation for everyday computing tasks and moderate workloads. The UDIMM form factor is characterized by its direct connection to the memory controller without an intermediate register, making it suitable for systems with fewer memory modules or less demanding memory configurations. This module features a CAS Latency (CL) of 15, offering a reasonable balance between access time and operational speed for DDR4 memory. The 2Rx8 organization indicates a dual-rank configuration, where each rank consists of DRAM chips with an 8-bit data width. Dual-rank modules can sometimes offer performance benefits in certain scenarios due to their ability to interleave operations between ranks. Crucially, this is a Non-ECC (Error-Correcting Code) memory module. This means it does not have the built-in error detection and correction capabilities found in ECC memory. Therefore, it is best suited for applications where data integrity is not as critical as in server environments, such as general-purpose workstations or gaming PCs. The standard 1.2V operating voltage ensures compatibility with a wide range of DDR4-compatible motherboards.
