Micron MT36HTF51272FZ-667HZN8ES 4GB DDR2-667MHz FB-DIMM 2Rx4 Memory

Product Description

The Micron MT36HTF51272FZ-667HZN8ES is a 4GB Fully Buffered DIMM (FB-DIMM) module, utilizing DDR2 SDRAM technology. This memory module is specifically designed for server and workstation applications where high memory capacity and data integrity are critical. The FB-DIMM architecture, characterized by its Advanced Memory Buffer (AMB) chip, allows for increased memory density and improved signal integrity, enabling systems to support larger amounts of RAM compared to earlier DIMM types. This particular module operates at a clock speed of 667MHz, providing a solid level of performance for DDR2-based systems. The 2Rx4 rank configuration indicates that the module has two ranks, with each rank consisting of memory chips that have a 4-bit data interface. This configuration is common for achieving higher capacities within a single DIMM while maintaining reasonable performance metrics for its generation. As with most FB-DIMMs, this Micron module includes built-in ECC (Error-Correcting Code) capabilities. ECC memory is essential in server environments as it can detect and correct single-bit memory errors, significantly reducing the risk of data corruption and system instability. While FB-DIMMs were known for higher power consumption and heat generation compared to later memory technologies, they were instrumental in enabling the high-capacity memory configurations required by demanding server workloads of their era. This module is a key component for maintaining or upgrading systems that utilize DDR2 FB-DIMM technology.
