Product Description
The Dell 0Y448H is a 2GB DDR2 Registered DIMM (RDIMM) memory module, engineered for server and workstation applications where stability and capacity are key. Operating at 667MHz, it provides a solid performance level for systems utilizing DDR2 memory technology. The module features a CAS Latency of CL5, which dictates the delay between the memory controller requesting data and the data becoming available, influencing overall system responsiveness. This RDIMM is organized as 2Rx4, meaning it is dual-ranked with four memory chips per rank. Dual-rank modules can offer performance benefits in certain server architectures by allowing the memory controller to access different ranks independently, potentially increasing bandwidth. The registered nature of the DIMM includes an onboard register that buffers address and command signals, reducing the electrical load on the memory controller and enabling higher memory configurations and improved signal integrity. As a server-grade memory module, the 0Y448H typically includes ECC (Error-Correcting Code) functionality. ECC memory can detect and correct common types of internal data corruption, significantly enhancing system reliability and data integrity, which is critical for preventing downtime and data loss in enterprise environments. This module is designed to be compatible with servers and workstations that specifically support DDR2 RDIMMs.
