Description
The HP 726724-S21 is a high-capacity 64GB DDR4 LRDIMM module, specifically designed to enhance the memory performance and capacity of HP ProLiant servers. Operating at a speed of 2133MHz, this module leverages the advancements of DDR4 technology to provide increased bandwidth and efficiency over previous generations. The LRDIMM (Load-Reduced DIMM) architecture is crucial for servers that require extensive memory configurations. It employs a memory buffer chip that reduces the electrical load on the memory controller, enabling the system to support a larger number of DIMMs and higher total memory capacities. The 4Rx4 rank configuration indicates a dense and high-performance arrangement of memory chips on the module. With a CAS Latency of CL15, this module offers a balance between speed and stability suitable for demanding enterprise workloads such as large databases, virtualization, and complex analytics. The integrated ECC (Error-Correcting Code) functionality ensures data integrity by detecting and correcting memory errors, which is paramount for mission-critical server uptime and reliability. This module is an ideal choice for upgrading HP servers that require substantial memory resources.
