Description
The HP WW559AV is an 8GB memory kit designed to enhance the performance of standard desktop computers and workstations. This kit includes two 4GB DDR3 UDIMM modules, providing a total of 8GB of RAM. DDR3 technology offers improved power efficiency and higher data transfer rates compared to previous DDR generations, making it a suitable choice for modern computing needs. The modules operate at a frequency of 1333MHz, which is a common speed for DDR3 memory, ensuring adequate performance for everyday tasks and moderate multitasking. As UDIMMs (Unbuffered DIMMs), these modules are directly connected to the memory controller without an intermediate register. This architecture is typical for consumer-grade desktops and many workstations, offering a cost-effective and reliable memory solution. The 2Rx8 configuration indicates that each 4GB module is dual-rank, with each rank comprising 8-bit wide DRAM chips. Dual-rank modules can sometimes provide a slight performance boost through memory interleaving, where the memory controller can access different ranks concurrently. The CL9 (CAS Latency 9) timing parameter specifies the delay in clock cycles between the memory controller's request for data and the data's availability. This latency is a key factor in memory performance. The HP WW559AV kit is a straightforward upgrade for systems that require more memory for smoother operation, such as running multiple applications simultaneously, browsing the web with many tabs open, or using productivity software. It represents a reliable and compatible memory expansion for a wide range of HP and other compatible systems.
