Product Description
The Micron MT18HTF12872FDY-667D5E4 is a 1GB DDR2 FB-DIMM memory module, engineered for demanding server and workstation environments. As a Fully Buffered DIMM, it incorporates an Advanced Memory Buffer (AMB) chip that serializes data, reducing bus loading and enabling higher memory capacities and speeds. This architecture is crucial for systems requiring extensive memory resources and high bandwidth. This module operates at a speed of 667MHz, corresponding to PC2-5300F specifications, and has a CAS Latency of CL5. The 2Rx8 designation indicates that it is a dual-rank module, utilizing two sets of memory chips (ranks), with each chip having an 8-bit data interface. This configuration allows for improved performance through parallel access by the memory controller. FB-DIMMs were a key technology in server platforms during the DDR2 era, offering advantages in signal integrity and scalability over unbuffered memory. The MT18HTF12872FDY-667D5E4 is a reliable component from Micron, suitable for applications that demand stability and high memory throughput, such as virtualization, large databases, and complex scientific simulations.
