Product Description
The HP PM842AVR is a memory upgrade kit specifically designed for older server and workstation systems that require DDR2 Registered DIMMs (RDIMMs). This kit provides a total of 1GB of memory, distributed across two 512MB modules. These modules operate at a speed of 400MHz, which was a common standard for DDR2 memory, offering adequate performance for systems of that era. The RDIMM format includes an onboard register that buffers memory commands and addresses, reducing the electrical load on the memory controller. This allows for greater memory capacity and improved stability in systems with multiple memory modules. The 1Rx8 configuration indicates a single rank with eight memory chips per rank, a standard setup for many DDR2 server modules. The CL3 latency is typical for DDR2 memory operating at this speed. This memory kit is suitable for upgrading or replacing memory in compatible HP servers and workstations that utilize DDR2 RDIMMs. It typically supports ECC (Error-Correcting Code) functionality, which is crucial for maintaining data integrity in server environments by detecting and correcting memory errors. The PM842AVR ensures compatibility and reliable operation for systems that still rely on DDR2 memory technology.
