Product Description
The Dell A0763391 is a 4GB DDR2 memory module that shares the same technical specifications as the A0763303, indicating it serves the same purpose within compatible Dell server systems. It is a Fully Buffered DIMM (FB-DIMM), a type of memory module that utilizes an Advanced Memory Buffer (AMB) chip to serialize data traffic between the memory controller and the DRAM devices. This architecture significantly boosts memory bandwidth and allows for greater memory capacities per channel. Operating at a frequency of 667MHz, this module provides substantial data transfer rates suitable for demanding server workloads. The 2Rx4 designation signifies a dual-rank configuration using x4 DRAM devices, which can offer performance benefits by enabling the memory controller to access different memory banks more efficiently. The CAS Latency (CL) is rated at 5, a standard timing for DDR2 FB-DIMMs at this speed. FB-DIMMs were a prevalent technology in server platforms requiring high memory bandwidth and density. They offer enhanced signal integrity and improved error handling compared to earlier unbuffered DIMMs. The Dell A0763391 is therefore a critical component for maintaining the performance and reliability of specific Dell server models that utilize this memory technology, ensuring efficient operation for critical business applications.
