Product Description
The HP E2Q92AAR is a 4GB DDR3 Synchronous Dynamic Random-Access Memory (SDRAM) module designed for enterprise-level computing. It operates at a high frequency of 1866MHz, enabling faster data access and improved system performance for memory-intensive tasks. As a Registered DIMM (RDIMM), it incorporates an onboard register that buffers command and address signals, reducing the electrical load on the memory controller. This feature is essential for maintaining signal integrity and allowing for higher memory configurations in servers and workstations. This memory module is equipped with Error-Correcting Code (ECC) functionality, which is critical for ensuring data integrity and system stability. ECC memory can detect and correct single-bit errors, preventing data corruption and system crashes that can occur in demanding environments. The CAS Latency (CL) is rated at CL13, representing the number of clock cycles required for the memory to respond to a column access command. This latency, combined with the 1866MHz speed, provides a robust performance profile suitable for various server applications. The 1Rx4 organization indicates a single-rank module with a data width of x4 per DRAM chip. This configuration is common for DDR3 RDIMMs and offers a good balance of performance and density. The 1.5V operating voltage is standard for DDR3 memory. The HP E2Q92AAR is a reliable component for upgrading or populating memory in compatible HP servers and workstations, contributing to enhanced processing capabilities and data reliability.
