Micron MT9HTF12872FZ-667EZD4ES 1GB DDR2-667MHz FB-DIMM 1Rx8 CL5 Memory

Description

The Micron MT9HTF12872FZ-667EZD4ES is a 1GB memory module specifically designed for server and workstation environments that utilize the Fully Buffered DIMM (FB-DIMM) architecture. FB-DIMMs were an intermediate memory technology used primarily in DDR2-based servers to overcome the limitations of standard DIMMs regarding signal integrity and scalability, allowing for higher memory capacities and speeds than were possible with unbuffered modules of the era. This module operates at DDR2-667MHz speed, also known as PC2-5300F, providing a data transfer rate suitable for demanding server workloads. The CAS Latency (CL) is 5 clock cycles. A key characteristic of FB-DIMMs is the presence of an Advanced Memory Buffer (AMB) chip on the module itself. This AMB chip serializes data traffic between the memory controller and the DRAM chips, effectively decoupling the memory bus from the DRAM speed and allowing for higher densities and improved signal integrity across multiple modules. As a server-grade memory module, it features ECC (Error-Correcting Code) functionality, which is crucial for detecting and correcting single-bit memory errors, thereby enhancing system stability and data integrity. The 1Rx8 organization indicates a single rank of memory chips, each with an x8 data width. While 1GB is a modest capacity by today's standards, this FB-DIMM was a common component in servers from the mid-2000s, supporting platforms that required robust memory performance and reliability.
