HP 16GB DDR4-2133 PC4-17000 ECC Registered RDIMM Server Memory Module

Upgrade your HP ProLiant Gen9 server with the HP 16GB DDR4-2133 PC4-17000 ECC Registered RDIMM memory module (726719-B21). Designed for demanding server environments, this high-performance RAM delivers reliable, error-corrected performance to support virtualization, database management, and enterprise applications.

Advantages

This memory module offers enhanced reliability with ECC (Error-Correcting Code) technology, which detects and corrects memory errors to prevent system crashes and data corruption. The registered (RDIMM) design reduces electrical load on the memory controller, allowing for larger memory configurations and improved stability in multi-module setups. With a speed of 2133 MHz and CAS latency of CL15, it provides a balanced performance for server workloads.
