HPE 840756-V91 16GB DDR4-2666MHz RDIMM 2Rx8 CL19 Memory

Product Description

The HPE 840756-V91 is a 16GB DDR4 Registered DIMM (RDIMM) memory module, engineered to deliver robust performance and data integrity for server environments. Operating at a speed of 2666MHz, this module facilitates faster data access and processing, which is essential for demanding enterprise workloads such as virtualization, database management, and high-performance computing. The module features a 2Rx8 configuration, indicating it is dual-rank with eight memory chips per rank. This design can offer performance advantages by allowing the memory controller to interleave operations between the ranks, potentially increasing bandwidth and reducing latency. The CAS Latency (CL) is rated at 19, specifying the number of clock cycles required for the memory to respond to a column access command. This specification is optimized for the module's speed and type, ensuring efficient operation within compatible systems. As an RDIMM, it incorporates a register chip that buffers command and address signals between the memory controller and the DRAM chips, reducing electrical load on the memory controller and enabling higher memory capacities and speeds. The inclusion of Error-Correcting Code (ECC) is vital for servers, as it automatically detects and corrects memory errors, preventing data corruption and system crashes. This makes the 840756-V91 a reliable choice for mission-critical applications.
