Product Description
The HPE P57666-001 is a 64GB DDR4 memory module specifically designed as a Load-Reduced DIMM (LRDIMM). LRDIMMs are engineered to reduce the electrical load on the memory controller, enabling systems to support significantly higher total memory capacities compared to standard RDIMMs or UDIMMs. This makes them ideal for servers and workstations that require massive amounts of RAM for intensive workloads such as large-scale virtualization, in-memory databases, and high-performance computing. Operating at a speed of 2933MHz, this module provides excellent data transfer rates, crucial for applications that are sensitive to memory bandwidth. The 4Rx4 configuration indicates that it is a quad-rank module, with each rank utilizing x4 DRAM devices. Quad-rank modules, especially when combined with LRDIMM technology, allow for maximum memory population density within a server's memory channels, maximizing the system's potential memory footprint. With a CAS Latency of CL21, the P57666-001 offers a balance between speed and latency. This module is intended for use in compatible HPE servers and other enterprise systems that support DDR4 LRDIMMs at 2933MHz. Its high capacity and advanced architecture make it a key component for organizations looking to maximize their server's memory capabilities for the most demanding computational tasks.
