Dell A2690220 1GB DDR2-667MHz FB-DIMM 2Rx8 CL5 Memory

Description

The Dell A2690220 is a 1GB DDR2 Fully Buffered DIMM (FB-DIMM) memory module, specifically designed for server and workstation platforms that utilize this advanced memory architecture. FB-DIMMs incorporate an Advanced Memory Buffer (AMB) chip on the module itself, which serializes data traffic between the memory module and the memory controller. This design allows for higher memory densities and improved signal integrity compared to traditional unbuffered DIMMs, especially in systems with many memory slots. Operating at a frequency of 667MHz (also known as PC2-5300), this module provides a significant bandwidth for memory-intensive tasks. The CAS Latency (CL) of 5 indicates the number of clock cycles required for the memory to access data. The 2Rx8 configuration signifies a dual-rank module with an x8 data width per rank, which can offer performance benefits in certain memory access patterns. These modules were commonly found in enterprise-grade servers from manufacturers like Dell, HP, and IBM during the DDR2 era. While DDR2 technology is now considered legacy, FB-DIMMs were a critical component for enabling larger memory capacities in servers of their time. The A2690220 module is built to meet the rigorous demands of server environments, offering reliability and performance for applications such as virtualization, database hosting, and scientific computing. It's important to note that FB-DIMMs are not compatible with standard DDR2 unbuffered DIMM slots and require specific motherboard support.
