Dell 6472FB667 512MB DDR2-667MHz FB-DIMM 1Rx8 CL5 Memory

Product Description

The Dell 6472FB667 is a 512MB memory module belonging to the DDR2 generation of SDRAM, specifically designed in the FB-DIMM (Fully Buffered DIMM) form factor. FB-DIMMs were a transitional technology used in servers and high-end workstations to overcome the limitations of traditional DIMMs, particularly regarding signal integrity and scalability at higher speeds and capacities. This module operates at a clock speed of 667MHz, which corresponds to a PC2-5300 data transfer rate, providing a moderate level of bandwidth for the systems it supports. The module features a CAS Latency (CL) of 5, indicating the number of clock cycles it takes for the memory to respond to a column address command. The 1Rx8 configuration signifies that it is a single-rank module with eight memory chips per rank, a standard configuration for many memory modules. The key characteristic of FB-DIMMs is the Advanced Memory Buffer (AMB) chip present on each module. This chip serializes and deserializes data, improving signal integrity over longer traces and allowing for more memory modules to be populated on a motherboard. Given its DDR2 and FB-DIMM specifications, the Dell 6472FB667 is intended for use in older server platforms that were designed to accommodate this specific type of memory. While DDR2 and FB-DIMMs are largely superseded by newer technologies like DDR3, DDR4, and DDR5, modules like this remain essential for maintaining the operational status of legacy server infrastructure. It provides the necessary memory capacity for systems that may still be in service for specific applications or environments.
