Product Description
The Micron MT18HTF25672FDY-667A4E2 is a 2GB memory module specifically designed for server and high-performance workstation environments that utilize DDR2 FB-DIMM technology. FB-DIMMs are characterized by an Advanced Memory Buffer (AMB) chip on the module, which helps to improve signal integrity and allows for higher memory densities and speeds compared to standard unbuffered DIMMs, particularly in systems with many memory slots. This module operates at a frequency of 667MHz, often referred to as PC2-5300F, providing substantial bandwidth for memory-intensive applications. The CAS Latency (CL) is rated at 5, indicating the number of clock cycles required for the memory to respond to a column address command. The 2Rx8 designation signifies that the module is dual-ranked, with each rank composed of eight memory chips (x8 organization), which can offer performance benefits in certain system configurations. As a Fully Buffered DIMM, it includes ECC (Error-Correcting Code) functionality, which detects and corrects single-bit memory errors, enhancing system stability and data integrity – a critical feature for servers. This Micron memory module is built to stringent quality standards, ensuring reliability and compatibility with systems that support DDR2 FB-DIMMs.
