HPE 805669-B21 16GB DDR4 ECC RDIMM SmartMemory
Overview
The HPE 805669-B21 is a 16GB DDR4 Registered ECC SmartMemory module designed for HPE ProLiant Gen9 server platforms. It is used to provide stable and validated memory expansion for enterprise workloads including virtualization, database processing, and business application hosting.
The module operates at 2133 MT/s (PC4-2133P) and uses ECC Registered DIMM architecture to ensure data integrity, correct memory errors, and maintain system stability during continuous server operation. This makes it suitable for production environments where uptime and reliability are critical.
It is commonly deployed in ProLiant rack and tower servers where scalable memory capacity is required for multi-VM environments and centralized application workloads. The RDIMM structure enables better signal integrity in multi-module configurations compared to unbuffered memory.
The module integrates with HPE SmartMemory validation technology, allowing system-level verification, optimized performance behavior, and improved reliability tracking within supported HPE Gen9 server ecosystems.
Typical Deployment Scenarios
- VMware and Hyper-V virtualization hosts
- HPE ProLiant Gen9 server upgrades
- Enterprise application servers
- Database workload environments
- File and print server memory expansion
- Branch office IT infrastructure
