Product Description
The HP 872638-B21 is a high-capacity memory module engineered to enhance the performance and responsiveness of compatible server and workstation systems. With 64GB of DDR4 memory operating at 2400MHz, it provides ample bandwidth for memory-intensive applications, large datasets, and complex virtualized environments. This module features a 4Rx4 rank configuration, indicating a quad-rank design with x4 data width per rank. This configuration is often utilized in high-density memory solutions to maximize the number of memory chips on a single DIMM, contributing to its large capacity. The Registered DIMM (RDIMM) form factor includes an onboard register that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and speeds. The CL17 CAS Latency signifies the number of clock cycles required to access a particular memory address. Combined with the 2400MHz speed, this module offers a balanced performance profile suitable for a wide range of enterprise computing tasks, including database management, scientific simulations, and content creation. Its ECC (Error-Correcting Code) capability ensures data integrity by detecting and correcting single-bit errors, crucial for mission-critical applications where reliability is paramount.
