Product Description
The Micron MT9HTF12872FY-80EE1D4 is a 1GB DDR2 Fully Buffered DIMM (FB-DIMM) memory module. FB-DIMMs were a server-grade memory technology that utilized an Advanced Memory Buffer (AMB) chip on each module to enhance signal integrity and allow for higher memory capacities and speeds compared to standard DDR2 unbuffered DIMMs. This technology was prevalent in servers and workstations during the DDR2 era. This specific module operates at a faster speed of 800MHz (PC2-6400F) compared to its 667MHz counterparts, offering improved bandwidth. It has a CAS Latency (CL) of 6. The 1Rx8 configuration denotes a single-rank module with an x8 data width per DRAM chip. Like all FB-DIMMs, it includes ECC (Error-Correcting Code) functionality, which is critical for maintaining system stability and data accuracy in server environments by detecting and correcting memory errors. FB-DIMMs were a key component for servers and high-performance workstations that required significant amounts of memory and high reliability. While DDR2 and FB-DIMM technology are now considered legacy, this module is essential for maintaining or upgrading older server systems that are not compatible with newer memory types. It's important to be aware that FB-DIMMs generate more heat than unbuffered DIMMs, necessitating adequate cooling within the server chassis.
