Dell A0422902 512MB DDR2-400MHz RDIMM 1Rx8 CL3 Memory

Product Description

The Dell A0422902 is a 512MB DDR2 Registered DIMM (RDIMM) memory module, designed for entry-level servers and workstations that utilize DDR2 memory technology. With a capacity of 512MB, it is suitable for systems with basic memory requirements or for upgrading older systems where larger capacities are not supported. The module operates at a frequency of 400MHz, which corresponds to PC2-3200R specifications, providing adequate bandwidth for less demanding tasks. As an RDIMM, this module includes an onboard register that buffers address and command signals, reducing the electrical load on the memory controller. This allows for greater stability and the potential to install more memory modules in a system compared to unbuffered DIMMs (UDIMMs). The 1Rx8 configuration indicates a single-rank module with an x8 data width, which is a common configuration for DDR2 memory. This memory module also features Error-Correcting Code (ECC) functionality. ECC memory can detect and correct single-bit errors, significantly improving system reliability and data integrity, which is a critical feature for server environments. The CL3 CAS Latency indicates the number of clock cycles required to access a specific memory column, representing a balance between performance and compatibility for DDR2 memory. This module is ideal for maintaining or upgrading older Dell systems that require specific DDR2 RDIMM specifications.
