Product Description
The HP PA897AV is an 8GB memory kit composed of four 2GB DDR2 Registered DIMMs (RDIMMs). This kit is engineered for server and workstation environments that demand high reliability and performance. DDR2 memory operates at lower voltages and higher frequencies than its predecessor, DDR, offering improved efficiency and speed. The 400MHz speed corresponds to the PC2-3200 standard, indicating a data transfer rate of 3200 MB/s. The RDIMM configuration includes an onboard register chip that buffers command and address signals. This reduces the electrical load on the memory controller, allowing for greater memory capacity and improved system stability, which is crucial for servers running mission-critical applications. Furthermore, the inclusion of ECC (Error-Correcting Code) technology enables the memory to detect and correct single-bit errors, significantly enhancing data integrity and preventing system crashes caused by memory corruption. This kit's 2Rx8 configuration (implied by standard 2GB DDR2 RDIMMs) means each module has two ranks of memory chips, each with an 8-bit data width. This configuration is common for server memory and provides a good balance of performance and density. The CAS Latency (CL) of 3 is relatively low for DDR2 memory, contributing to efficient data access. The HP PA897AV is suitable for upgrading or populating memory in compatible HP ProLiant servers and other workstations that support DDR2 400MHz RDIMMs.
