HP PM842AV 1GB Kit (2x512MB) DDR2-400MHz RDIMM 1Rx8 CL3 Memory

Product Description

The HP PM842AV is a 1GB memory kit composed of two 512MB DDR2 Registered DIMMs (RDIMMs), designed for server and workstation environments that require ECC (Error-Correcting Code) memory. Each module operates at a speed of 400MHz, corresponding to the PC2-3200 standard, providing a stable and reliable memory foundation for demanding computing tasks. The RDIMM architecture includes an onboard register that buffers command and address signals, which helps to reduce electrical load on the memory controller, enabling greater memory capacity and improved system stability, particularly in multi-processor configurations. Each 512MB module in this kit features a 1Rx8 rank configuration, indicating a single rank of DRAM chips, with each chip having eight data lines. This configuration is typical for smaller capacity DDR2 modules. The modules are specified with a CAS Latency (CL) of 3, which represents a relatively low latency for DDR2 memory, contributing to efficient data access. The inclusion of ECC functionality is critical for servers, as it allows for the detection and correction of single-bit memory errors, thereby enhancing data integrity and preventing system downtime. As an HP-branded component, the PM842AV kit is built to meet the high standards of quality and compatibility expected for HP server and workstation platforms. This 1GB kit is suitable for upgrading older systems or for configurations where a specific, smaller amount of ECC DDR2 memory is required. It ensures reliable performance and data accuracy for essential business operations and critical applications.
