Description
The HP 814790-B21 is a 32GB Load-Reduced DIMM (LRDIMM) module designed for servers that require high memory capacity and performance. Operating at DDR4-2133MHz speeds, it provides a solid foundation for memory-intensive workloads. The PC4-17000 designation indicates its data transfer rate, ensuring compatibility with systems supporting this DDR4 standard. As a Load-Reduced DIMM (LRDIMM), this module incorporates a memory buffer chip that reduces the electrical load on the memory controller. This allows for higher memory densities per channel and across more memory slots, making it ideal for servers configured with large amounts of RAM. The 4Rx4 configuration signifies a quad-rank design, with each rank comprising four data bits per DRAM chip, contributing to both performance and density. This LRDIMM supports Error-Correcting Code (ECC), which is essential for server environments to ensure data integrity and system stability by detecting and correcting memory errors. The CL15 latency timing indicates the number of clock cycles required for data access. The 814790-B21 is a suitable choice for enterprise servers needing substantial, reliable memory capacity.
