Micron MT18HTF12872FY-667B4D1 1GB DDR2-667MHz FB-DIMM 1Rx8 CL5 Memory

Product Description

The Micron MT18HTF12872FY-667B4D1 is a 1GB DDR2 FB-DIMM memory module, engineered for server and workstation applications demanding high reliability and performance. This module operates at a speed of 667MHz, providing the necessary bandwidth for memory-intensive tasks and multitasking environments. The DDR2 technology, combined with the FB-DIMM architecture, allows for efficient data transfer and supports higher memory densities compared to traditional unbuffered DIMMs. The Advanced Memory Buffer (AMB) chip on the FB-DIMM serializes data, reducing electrical load and enabling higher clock speeds and improved signal integrity across the memory bus. This specific module features a CAS Latency (CL) of 5, which defines the timing delay between the memory controller issuing a read command and the data becoming available. The 1Rx8 organization indicates a single rank configuration with an 8-bit data width per DRAM chip, a standard setup for many server memory modules. The 1.8V operating voltage is typical for DDR2 memory. The inclusion of ECC (Error-Correcting Code) is a critical feature for server environments, as it provides enhanced data integrity by detecting and correcting memory errors, thereby preventing system crashes and data corruption. As part of Micron's extensive memory portfolio, the MT18HTF12872FY-667B4D1 is built to meet the rigorous standards of enterprise computing. Its specifications make it suitable for a wide range of server platforms that support DDR2 FB-DIMMs, offering a reliable solution for memory upgrades or replacements. The part number suffix '-667B4D1' likely denotes specific manufacturing or testing revisions, but the core technical specifications remain consistent with the 1GB DDR2-667MHz FB-DIMM 1Rx8 ECC standard.
