Product Description
The Samsung M391B1G73QH0-YK0 is an 8GB DDR3 memory module designed for a wide range of computing platforms, including desktops and entry-level servers. Its Unbuffered DIMM (UDIMM) configuration makes it suitable for systems where direct memory controller access is preferred or required, offering a cost-effective solution for memory upgrades. The module operates at a speed of 1600MHz, often referred to as PC3-12800, providing a significant performance boost over older DDR3 generations. This module features a 2Rx8 organization, meaning it is dual-ranked with an x8 data width per DRAM chip. This configuration can enhance performance by allowing the memory controller to access different ranks, improving efficiency in multitasking scenarios. The CAS Latency (CL) is rated at 11, which dictates the number of clock cycles required to access a particular column of data. This timing, combined with the 1600MHz frequency, ensures a responsive computing experience for everyday tasks and more demanding applications. Furthermore, the M391B1G73QH0-YK0 supports Error-Correcting Code (ECC) functionality. While UDIMMs with ECC are less common than their RDIMM counterparts, they are available for specific server and workstation motherboards that can utilize this feature for enhanced data integrity. This capability helps detect and correct minor memory errors, contributing to system stability. Samsung's reputation for quality ensures this module meets stringent manufacturing standards for reliability and compatibility.
