Product Description
The HP PT965AV is a 4GB memory kit consisting of four 1GB DDR2 Registered DIMM (RDIMM) modules. This configuration is specifically tailored for server environments where enhanced memory stability, reliability, and the ability to support larger memory capacities are essential. Operating at a speed of 533MHz, these modules provide a PC2-4200R data transfer rate, suitable for demanding server workloads. The inclusion of ECC (Error-Correcting Code) is a standard feature for RDIMMs, ensuring data integrity by detecting and correcting single-bit errors. Each module in this kit is configured as 1Rx4, meaning it is single-rank and utilizes four DRAM chips per rank. This configuration is often chosen for its balance of density and performance in server applications. The CAS Latency (CL) is rated at 4 clock cycles, which, combined with the 533MHz clock speed, offers a respectable level of performance for memory-intensive server tasks. The 1.8V operating voltage is standard for DDR2 memory modules. The Registered DIMM (RDIMM) architecture includes an onboard register that buffers command and address signals between the memory controller and the DRAM chips. This buffering reduces the electrical load on the memory controller, allowing servers to support a greater number of memory modules and higher total memory capacities compared to unbuffered DIMMs. The PT965AV kit is a reliable solution for upgrading or populating memory in compatible HP servers or other systems that require DDR2 RDIMMs with these specific specifications, ensuring stable operation and efficient data processing.
