Product Description
This Micron MT18KSF51272AZ-1G4K1ZE module provides 4GB of DDR3 SDRAM, operating at a frequency of 1333MHz. It is an Unbuffered DIMM (UDIMM), which is commonly used in desktop computers, workstations, and some entry-level servers that do not require ECC (Error-Correcting Code) memory. The 2Rx8 configuration indicates that the module is dual-rank, with each rank consisting of eight memory chips organized in banks, which can offer performance benefits in certain memory controllers. The module adheres to the DDR3 standard, offering a balance of performance and power efficiency. With a CAS Latency (CL) of 9, it provides a responsive memory access time suitable for general computing tasks, multitasking, and moderate application workloads. The standard operating voltage for DDR3 is 1.5V, ensuring compatibility with a broad range of motherboards designed for this memory generation. This 4GB DDR3 UDIMM is a reliable choice for upgrading existing systems or for building new ones where 4GB of standard DDR3 memory is specified. Its specifications make it a versatile component for users looking to enhance system performance for everyday computing, office productivity, or light gaming.
