Micron MT36HTF51272FDY-667G1D6 4GB DDR2-667MHz FB-DIMM 4Rx8 CL5 Memory

Product Description

The Micron MT36HTF51272FDY-667G1D6 is a 4GB memory module specifically designed for server applications that utilize the DDR2 Fully Buffered DIMM (FB-DIMM) standard. Operating at a frequency of 667MHz, which corresponds to the PC2-5300F specification, this module provides a significant bandwidth for data-intensive server tasks. FB-DIMMs were characterized by an Advanced Memory Buffer (AMB) chip on each module, which managed data flow, enabling higher memory densities and speeds compared to traditional unbuffered DIMMs of the DDR2 era. This module features a 4Rx8 configuration, indicating it is quad-rank with each rank composed of x8 (8-bit wide) DRAM chips. This configuration can offer performance advantages in certain server workloads by allowing for more simultaneous memory accesses. The CAS Latency (CL) is rated at CL5, which is a common timing for DDR2 memory operating at this speed, balancing responsiveness with stability. As a Fully Buffered DIMM, this memory module inherently supports ECC (Error-Correcting Code) functionality, which is critical for server environments where data integrity and system uptime are paramount. The AMB chip on the FB-DIMM handles the buffering and error correction, reducing the load on the memory controller and enabling higher memory capacities per channel. This Micron 4GB DDR2 FB-DIMM is suitable for servers that were designed to accommodate this specific memory technology, providing a reliable and performant memory solution for their intended applications.
