Product Description
The Dell 0Y4621 is a 4GB DDR2 Registered DIMM (RDIMM) memory module, specifically designed for server and workstation environments where data integrity and system stability are paramount. Operating at a frequency of 400MHz, this module provides a reliable foundation for systems that utilize DDR2 memory technology. The low CAS Latency of CL3 contributes to efficient data retrieval, ensuring that the processor can access information quickly. This RDIMM features a 2Rx4 organization, indicating that it is a dual-rank module with four memory chips per rank. Dual-rank configurations can enhance performance by allowing the memory controller to interleave operations between the ranks, potentially increasing bandwidth and improving overall system efficiency. The registered nature of the DIMM includes an onboard register that buffers command and address signals, reducing the electrical load on the memory controller and enabling support for larger memory capacities and improved signal integrity. As a component intended for server use, the 0Y4621 likely incorporates ECC (Error-Correcting Code) capabilities. ECC memory is crucial for detecting and correcting single-bit errors that can occur during data transmission or storage, thereby preventing system crashes and data corruption. This makes the module an ideal choice for mission-critical applications and environments where data accuracy is non-negotiable. It is compatible with servers and workstations that support DDR2 RDIMMs.
