Samsung M391B5273DH0-YH9 4GB DDR3-1333MHz UDIMM 2Rx8 CL9 Memory

Product Description

The Samsung M391B5273DH0-YH9 is a high-quality 4GB DDR3 memory module designed to enhance the performance of compatible computer systems. Operating at a speed of 1333MHz, it provides a significant boost in data transfer rates compared to older DDR generations, making it suitable for a wide range of computing tasks. The module utilizes Unbuffered DIMM (UDIMM) technology, which is commonly found in desktop computers and entry-level servers, offering a balance of performance and cost-effectiveness. This specific module features a CAS Latency (CL) of 9, indicating the number of clock cycles required to access data. Combined with its 1333MHz speed, it delivers efficient memory operations for everyday applications, multitasking, and general productivity. The 2Rx8 configuration signifies that the module is dual-ranked, with each rank utilizing eight memory chips (x8), which can sometimes offer performance benefits in certain system architectures by allowing the memory controller to access different ranks independently. With a standard operating voltage of 1.5V, the M391B5273DH0-YH9 is compliant with DDR3 specifications and is designed for reliability. It is important to note that this is a Non-ECC (Error-Correcting Code) module, meaning it does not have built-in error detection and correction capabilities. Therefore, it is best suited for systems where ECC is not a requirement, such as most consumer-grade desktops and some workstations or servers.
