0C739M - Dell 2GB DDR2-667MHz PC2-5300 ECC Fully Buffered CL5 240-Pin DIMM Dual Rank Memory Module

Description

The Dell 0C739M is a 2GB DDR2 memory module that utilizes the Fully Buffered DIMM (FB-DIMM) technology. FB-DIMMs were developed to overcome the signaling limitations of traditional DDR2 DIMMs, enabling higher memory capacities and speeds in server environments. A key feature of FB-DIMMs is the Advanced Memory Buffer (AMB) chip located on the module, which serializes and deserializes data, reducing the electrical load on the memory controller. This module operates at a speed of 667MHz, providing adequate bandwidth for many server applications of its era. The CL5 CAS latency is characteristic of DDR2 FB-DIMMs. The 2Rx8 organization signifies a dual-rank module, where each rank uses x8 (8-bit) data chips, contributing to its overall performance and capacity. FB-DIMMs were primarily used in servers from manufacturers like Dell, HP, and IBM during the transition period from DDR2 to DDR3. While they allowed for greater memory scalability, they also consumed more power and generated more heat than unbuffered or registered DIMMs. The 0C739M is a specific component for servers that were designed to leverage this fully buffered memory architecture.
