Description
This Micron MT18HTF25672FDY-667A5E3 module is a 2GB DDR2 Fully Buffered DIMM (FB-DIMM) memory stick, engineered for demanding server and workstation applications. It operates at a frequency of 667MHz, providing a significant bandwidth increase essential for memory-intensive tasks. The FB-DIMM architecture, featuring an Advanced Memory Buffer (AMB), isolates the memory chips from the memory controller, reducing electrical load and enabling higher memory densities and improved signal integrity, which is critical for system stability in multi-module configurations. The module is configured as 2Rx8, indicating it is dual-ranked with each rank utilizing x8 data-width DRAM chips. This configuration is often chosen for its balance of performance and density in server environments. The memory speed of 667MHz, also known as PC2-5300, translates to a theoretical peak data transfer rate of approximately 5.3 GB/s. The CAS Latency (CL) is rated at 5 clock cycles, which is a standard timing parameter affecting memory access latency. When combined with the clock speed, it determines the actual latency in nanoseconds. Crucially for server environments, this module supports ECC (Error-Correcting Code). ECC memory can detect and correct single-bit errors and detect multi-bit errors, significantly enhancing data reliability and preventing system crashes due to memory faults. The module operates at the standard 1.8V for DDR2 FB-DIMMs. Its specifications make it a suitable component for upgrading or populating memory in servers and workstations that are designed to support DDR2 FB-DIMM modules, ensuring robust performance and data integrity.
