Product Description
The HP PR789AV memory kit provides a total of 4GB of RAM, distributed across four 1GB Registered DIMM (RDIMM) modules. This configuration is specifically designed for server and enterprise-grade workstation applications where memory stability, reliability, and error correction are critical. The DDR2 technology, operating at 400MHz (PC2-3200), offers a solid foundation for systems requiring dependable memory performance for everyday server tasks and moderate workloads. Each module in this kit features a 1Rx4 organization, indicating a single rank with four memory chips per rank. This configuration is common in server memory and is optimized for compatibility with various server chipsets. The RDIMM form factor includes onboard registers that buffer data signals between the memory modules and the memory controller. This buffering reduces the electrical load on the controller, enabling systems to support larger amounts of memory and maintain signal integrity, which is crucial for system stability under continuous operation. Furthermore, these RDIMMs are ECC (Error-Correcting Code) enabled. ECC memory can detect and correct single-bit errors and detect multi-bit errors, significantly reducing the risk of data corruption and system crashes. This feature, combined with the registered nature of the DIMMs, makes the PR789AV kit a reliable choice for mission-critical server environments. The CAS Latency (CL) of 3 contributes to the module's timing characteristics, influencing overall system responsiveness.
