Product Description
The HP PT961AVR is a memory kit designed for older generation servers and workstations that utilize DDR2 technology. This kit provides a total of 2GB of memory, distributed across four 512MB Registered DIMM (RDIMM) modules. The DDR2 standard offers improvements over DDR in terms of speed and efficiency, and the 533MHz frequency (PC2-4200) was a common speed for enterprise-grade DDR2 memory. As Registered DIMMs, these modules include an onboard register that buffers command and address signals. This architecture reduces the electrical load on the memory controller, enabling systems to support higher memory capacities and enhancing overall stability, which is crucial for server environments. The 1Rx8 configuration indicates that each module is Single Rank with an x8 data width per DRAM chip, a standard configuration for many DDR2 modules. With a CAS Latency (CL) of 4, these modules offer relatively fast response times for DDR2 memory. This kit is suitable for maintaining or upgrading legacy HP servers and other systems that specifically require DDR2-533MHz RDIMMs. The combination of registered architecture and specific speed/latency makes it a reliable component for ensuring the continued operation of older enterprise hardware.
