Product Description
The HP 840756-091U is a high-performance 16GB DDR4 Registered DIMM (RDIMM) module, specifically engineered for server and enterprise environments. With a speed of 2666MHz, it offers significantly faster data transfer rates compared to lower-speed memory, enhancing overall system performance for demanding applications. The inclusion of ECC (Error-Correcting Code) technology is critical for servers, as it detects and corrects single-bit memory errors, preventing data corruption and system crashes. This RDIMM features a 2Rx8 (Dual Rank x8) configuration, which can improve memory performance by allowing the memory controller to access different banks of memory more efficiently. The CL19 CAS latency indicates the number of clock cycles required to access a specific memory column. While slightly higher than CL17, the 2666MHz speed often compensates for this in overall throughput for server workloads. Designed for reliability and stability, the 1.2V operating voltage is standard for DDR4 memory. This module is ideal for upgrading existing server memory or for building new systems that require robust and error-free operation. The HP 840756-091U is a crucial component for maintaining the integrity and performance of critical server infrastructure.
