Product Description
This Samsung 8GB DDR3 UDIMM module, model M391B1G73QH0-CK0, is a standard memory component suitable for a wide range of computing systems, including desktops, workstations, and entry-level servers. Operating at a speed of 1600MHz (also known as PC3-12800), it provides a good balance of performance and power efficiency for everyday computing tasks. The UDIMM form factor means it is unbuffered, directly connecting to the memory controller, which is typical for consumer-grade motherboards and many server boards. The 2Rx8 configuration signifies that the module is dual-rank, with each rank having an x8 data width. Dual-rank modules can sometimes offer a slight performance advantage over single-rank modules due to the way the memory controller can access different ranks independently. With a CAS Latency (CL) of 11, this module offers a reasonable response time for its speed, contributing to overall system responsiveness. It operates at the standard DDR3 voltage of 1.5V, ensuring compatibility with a broad spectrum of DDR3-compatible motherboards. This particular module is a non-ECC (Error-Correcting Code) memory, meaning it does not have the built-in error detection and correction capabilities found in ECC memory. Therefore, it is best suited for systems where data integrity is not as critical as in server environments handling sensitive financial or scientific data. Users should confirm their system's compatibility with DDR3 UDIMMs, 1600MHz speed, and 8GB capacity before installation to ensure seamless integration and optimal performance.
