Micron MT18HTF25672FDY-667EYE4ES 2GB DDR2-667MHz FB-DIMM 2Rx8 Memory

Product Description

The Micron MT18HTF25672FDY-667EYE4ES is a 2GB Fully Buffered DIMM (FB-DIMM) memory module, engineered for server and high-performance computing environments. It adheres to the DDR2 SDRAM standard, operating at a frequency of 667MHz, which corresponds to the PC2-5300F specification. The FB-DIMM form factor includes an Advanced Memory Buffer (AMB) chip on each module, which serializes data transfers and reduces the electrical load on the memory controller, enabling greater memory scalability in systems with multiple memory channels. This module features a 2Rx8 configuration, meaning it is dual-ranked with each rank composed of x8 DRAM chips. Dual-rank modules can sometimes offer improved performance by allowing the memory controller to interleave accesses between ranks. Crucially for server applications, this memory module includes Error-Correcting Code (ECC) functionality. ECC memory is designed to detect and correct common types of memory errors, thereby enhancing system stability and data integrity, which is vital for preventing data loss and ensuring continuous operation in critical workloads. The 'EYE4ES' suffix in the part number likely indicates specific Micron product revisions or quality grades, but the fundamental technical specifications remain consistent with its role as a reliable server memory component. FB-DIMMs were a prevalent memory technology in servers during the DDR2 generation, supporting higher memory capacities than previous unbuffered modules. This module is suitable for systems that require robust memory performance and reliability for demanding enterprise applications.
