Micron MT18HTF25672FDY-667AZE4ES 2GB DDR2-667MHz FB-DIMM 2Rx8 Memory

Description

The Micron MT18HTF25672FDY-667AZE4ES is a 2GB Fully Buffered DIMM (FB-DIMM) memory module, part of Micron's line of server-grade memory. It operates at DDR2 speeds, specifically 667MHz (often referred to as PC2-5300F), and is configured as 2Rx8, indicating dual-rank operation with x8 DRAM chips. FB-DIMMs were a key technology for scaling memory capacity in servers during the DDR2 era, featuring an onboard buffer chip that improved signal integrity and allowed for more DIMMs per channel compared to unbuffered DIMMs. This module is equipped with Error-Correcting Code (ECC) capabilities, which are essential for server environments where data integrity and system stability are paramount. ECC memory can detect and correct single-bit errors and detect multi-bit errors, preventing data corruption and system crashes. The 2Rx8 configuration means the memory is organized into two ranks, each utilizing x8 data width DRAM chips, which can influence performance depending on the memory controller and workload. FB-DIMMs require specific motherboard support and are typically found in servers and high-end workstations from the mid-2000s. The 'AZE4ES' suffix in the part number likely denotes specific manufacturing or testing variations, but the core technical specifications (2GB, DDR2-667, FB-DIMM, 2Rx8, ECC) remain consistent with its intended use in demanding server applications. This memory module is designed to provide reliable and efficient performance for memory-intensive tasks in enterprise computing.
