Product Description
The Micron MT9RTF12872FY-667G1N8 is a 1GB memory module utilizing DDR2 technology, specifically designed in the FB-DIMM (Fully Buffered DIMM) form factor. FB-DIMMs were developed to overcome the scalability limitations of traditional DIMMs by incorporating an Advanced Memory Buffer (AMB) chip on each module. This buffer serializes data, reducing the electrical load on the memory controller and enabling higher memory capacities and speeds in server environments. Operating at a frequency of 667MHz (equivalent to PC2-5300F), this module provides a significant bandwidth suitable for memory-intensive server applications. The CAS Latency (CL) of 5 indicates the number of clock cycles required to access a particular memory column. The 1Rx8 rank configuration signifies a single rank of memory chips, each with an 8-bit data width, which is standard for many DDR2 modules. While FB-DIMMs offered advantages in density and scalability, they also generated more heat and consumed more power compared to later DDR3 and DDR4 technologies. Nevertheless, for systems that were designed to utilize FB-DIMMs, modules like the MT9RTF12872FY-667G1N8 were essential for achieving the required memory capacity and performance. This particular module is ideal for upgrading or populating servers that specify DDR2 FB-DIMM memory.
