Product Description
The Micron MT18HTF25672FDY-53EA4E3 is a 2GB DDR2 Fully Buffered DIMM (FB-DIMM) memory module, designed for server platforms that utilize this advanced memory technology. FB-DIMMs were developed to overcome the limitations of traditional Registered DIMMs (RDIMMs) in high-density memory configurations by introducing an Advanced Memory Buffer (AMB) chip on each module. This AMB chip serializes and deserializes data, effectively isolating the memory modules from the memory controller and allowing for significantly higher memory capacities and improved signal integrity across more memory channels. This specific module operates at 533MHz, corresponding to the PC2-4200 standard, providing a substantial data transfer rate suitable for demanding server workloads. The 2Rx8 configuration indicates a dual-rank design, where each rank consists of eight memory chips. The CL4 CAS Latency specifies the number of clock cycles required for the memory controller to access a specific column of data. FB-DIMMs inherently include advanced error correction capabilities, offering robust data integrity essential for server environments. The FB-DIMM architecture, while offering advantages in density and scalability, typically consumes more power and generates more heat than RDIMMs due to the AMB chip. However, for systems designed to support FB-DIMMs, modules like the MT18HTF25672FDY-53EA4E3 provide a reliable and high-performance memory solution. This 2GB module is suitable for servers requiring substantial memory capacity and advanced error management features within the DDR2 generation.
