HPE 669322-B21 – 4GB DDR3 ECC UDIMM Server Memory

HPE 669322-B21 4GB DDR3 ECC UDIMM Server Memory

Overview

Overview

The HPE 669322-B21 is a 4GB DDR3 ECC Unbuffered DIMM designed for HPE ProLiant Gen8 server platforms. It is used for basic server memory expansion in entry-level enterprise systems running file services, lightweight virtualization, and general application workloads.

The module operates at 1600 MHz (PC3-12800E) and uses unbuffered ECC architecture to provide error detection and correction while maintaining lower cost and simpler memory channel design compared to registered modules. It is suitable for systems that require stable but entry-level memory performance.

This module is commonly deployed in ProLiant Gen8 servers such as DL and ML series platforms where UDIMM support is required. It follows standard 240-pin DDR3 DIMM design for compatibility with supported server motherboards.

The memory is validated for HPE ProLiant environments and integrates into ECC-enabled memory channels to ensure system stability during continuous operation in small to mid-range server workloads.

Typical Deployment Scenarios

• HPE ProLiant Gen8 server upgrades
• Entry-level virtualization hosts
• File and print server memory expansion
• Small business application servers
• Branch office infrastructure systems
• Light database workloads
