Product Description
The Micron MT9HTF12872FY-667G1N8 is a 1GB DDR2 Fully Buffered DIMM (FB-DIMM) memory module. FB-DIMMs were designed to overcome the scalability limitations of traditional DDR2 unbuffered DIMMs by incorporating an Advanced Memory Buffer (AMB) chip on each module. This buffer isolates the memory controller from the DRAM chips, allowing for higher memory capacities and speeds in server environments. This module operates at a speed of 667MHz (PC2-5300F) with a CAS Latency (CL) of 5. The 1Rx8 organization indicates it is a single-rank module with an x8 data width per DRAM chip. FB-DIMMs also feature ECC (Error-Correcting Code) capabilities, which are essential for server stability and data integrity by detecting and correcting memory errors. FB-DIMMs were primarily used in servers and high-end workstations from the mid-2000s. While DDR2 and FB-DIMM technology are now considered legacy, modules like this are still crucial for maintaining and upgrading older server infrastructure. It's important to note that FB-DIMMs run hotter than unbuffered DIMMs due to the AMB chip and require adequate system cooling.
