Description
The HP 647763-001 is a 16GB Registered DIMM (RDIMM) memory module utilizing DDR3 SDRAM technology. With a speed of 1333MHz, it provides a significant performance boost for servers and workstations, enabling faster data processing and improved system responsiveness. The RDIMM format includes a register that buffers memory commands and addresses, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in multi-processor systems. The module's 2Rx4 configuration indicates it has two ranks of memory chips, each rank consisting of four memory chips per chip select. This configuration can offer performance benefits and is common in enterprise memory modules. The CL9 CAS Latency specifies the delay between the memory controller requesting data and the data being available, with CL9 being a standard latency for DDR3-1333MHz modules. This 16GB memory module is designed to enhance the multitasking capabilities and overall performance of compatible HP servers and workstations. It is an ideal component for upgrading existing systems or for building new ones that require substantial and reliable memory capacity for demanding applications, virtualization, or large datasets.
