Micron MT9HTF6472FY-667A2D2 512MB DDR2-667MHz FB-DIMM 1Rx8 CL5 Memory

Product Description

The Micron MT9HTF6472FY-667A2D2 is a 512MB memory module utilizing DDR2 SDRAM technology, operating at a speed of 667MHz, which corresponds to the PC2-5300 standard. This module is a Fully Buffered DIMM (FB-DIMM), a type of memory module designed for servers and workstations that incorporates an Advanced Memory Buffer (AMB) chip. The AMB chip serializes data transfers between the memory controller and the memory chips, enabling higher memory densities and improved signal integrity, albeit with slightly increased latency compared to unbuffered modules. This specific module is configured as 1Rx8, meaning it is single-ranked with memory chips organized in an 8-bit data width. FB-DIMMs typically include an integrated heat spreader or heatsink on the AMB chip, which is essential for managing the heat generated by the buffer. The module also supports ECC (Error-Correcting Code) functionality, which is crucial for server environments to ensure data integrity and system stability by detecting and correcting memory errors. While DDR2 and FB-DIMM technology are older standards, modules like the MT9HTF6472FY-667A2D2 were vital for building high-capacity and reliable server systems in their time. They provided the necessary memory bandwidth and error correction for demanding enterprise workloads before the advent of DDR3 and subsequent memory generations.
