Product Description
The Micron MT18HTF12872JDY-667D6D4 is a 1GB DDR2 FB-DIMM memory module designed for server and workstation applications demanding high reliability and performance. This module operates at a speed of 667MHz (PC2-5300) with a CAS Latency of 5 (CL5), providing efficient data transfer rates. The Fully Buffered DIMM (FB-DIMM) architecture, featuring an Advanced Memory Buffer (AMB) chip, serializes data traffic, reducing electrical loading and enabling higher memory speeds and capacities. This makes it suitable for memory-intensive tasks and environments requiring substantial memory resources. The key distinction for this module is its 2Rx8 organization, meaning it consists of two ranks of DRAM chips, with each chip having an 8-bit data width. Dual-rank modules can sometimes offer performance advantages in certain server architectures by allowing the memory controller to access data from different ranks concurrently, potentially improving efficiency. It operates at the standard DDR2 voltage of 1.8V. As with other server-grade memory, it includes ECC (Error-Correcting Code) functionality, which is crucial for detecting and correcting memory errors, thereby ensuring data integrity and system stability. This specific part number, MT18HTF12872JDY-667D6D4, is a Micron product, indicating a commitment to quality and reliability. The suffix '-667D6D4' likely refers to specific manufacturing, testing, or packaging details within Micron's product codes. It is designed for compatibility with server platforms that support DDR2 FB-DIMMs, serving as a dependable component for memory upgrades or replacements in demanding IT infrastructures.
