Product Description
The Micron MT18HTF12872FDY-667D5E3 is a 1GB DDR2 Fully Buffered DIMM (FB-DIMM) memory module, specifically designed for server and workstation environments that require high memory bandwidth and reliability. The FB-DIMM architecture incorporates an Advanced Memory Buffer (AMB) chip on the module itself, which serializes data to and from the memory controller. This design significantly reduces electrical loading on the memory bus, allowing for higher densities and speeds compared to traditional Unbuffered DIMMs (UDIMMs). Operating at a frequency of 667MHz (often referred to as PC2-5300F), this module provides substantial bandwidth for memory-intensive applications. The CAS Latency of CL5 indicates the number of clock cycles it takes for the memory to respond to a column address command. The 2Rx8 configuration signifies that the module is dual-ranked, meaning it has two independent sets of memory chips (ranks) that the memory controller can access. Each chip within these ranks has an 8-bit data width. This specific FB-DIMM is a component for systems that utilize DDR2 memory technology. FB-DIMMs were prevalent in server platforms during the DDR2 era due to their ability to support larger memory capacities and improved signal integrity, crucial for mission-critical operations. The Micron brand is known for its quality and reliability in memory manufacturing.
