Product Description
The HP E2Q91ATR is a 4GB DDR3 Unbuffered DIMM (UDIMM) memory module, engineered to enhance the performance of compatible HP business desktops and workstations. This module offers a significant boost in memory capacity, enabling smoother multitasking, faster application loading, and improved overall system responsiveness. The DDR3 technology represents a mature and reliable standard for system memory, providing a solid foundation for everyday computing tasks. Operating at a high frequency of 1866MHz (PC3-14900), this memory module ensures rapid data transfer rates between the system's memory controller and the processor. This elevated speed is particularly beneficial for memory-intensive applications and workloads. The module is configured as 2Rx8, meaning it is dual-rank with an x8 data organization per rank. This configuration can potentially offer performance benefits in certain system architectures by allowing for more efficient access patterns. With a CAS Latency (CL) of 13, the E2Q91ATR strikes a balance between speed and latency. While higher frequencies generally lead to faster performance, latency also plays a crucial role. This module is designed to provide a good overall performance profile for a wide range of business computing needs. As a single module, it can be used to upgrade existing memory configurations or fill an available slot in compatible HP systems, provided the system supports DDR3-1866MHz speeds and UDIMM form factors.
