Product Description
The HP E2Q91A6R is a 4GB DDR3 Unbuffered DIMM (UDIMM) memory module engineered for enhanced performance in compatible HP servers and workstations. Operating at a higher frequency of 1866MHz, it offers increased bandwidth compared to lower-speed DDR3 modules, which can significantly improve application responsiveness and system throughput. The 2Rx8 configuration indicates a dual-rank design utilizing x8 DRAM devices, potentially optimizing memory access patterns for certain processors and motherboards. This memory module features a CAS Latency (CL) of 13, which is a common timing for DDR3-1866MHz modules. While slightly higher than CL11, it is optimized for the increased clock speed, ensuring efficient data transfer. The standard 1.5V operating voltage ensures compatibility with systems designed for DDR3 memory. This is a non-ECC module, meaning it does not have error correction capabilities built-in, making it suitable for environments where ECC is not a requirement or is handled by other system components. This 4GB DDR3-1866MHz UDIMM is an excellent choice for upgrading systems that require faster memory performance for tasks such as virtualization, database operations, or multimedia processing. Its specifications provide a noticeable performance uplift for memory-bound applications. The module is built to HP's quality standards, ensuring reliability and compatibility within the HP ecosystem.
