HPE 500656-B21 – 2GB DDR3 ECC RDIMM

HPE 500656-B21 – 2GB DDR3 ECC RDIMM

Overview

The HPE 500656-B21 is a 2GB DDR3 Registered ECC memory module designed for HPE ProLiant G6 and G7 server platforms. It is used to provide reliable system memory expansion in entry-level enterprise servers where stability and ECC error correction are required for continuous workloads.

The module operates at 1333 MHz (PC3-10600) and uses registered dual-rank architecture to support server-grade memory reliability and improved signal integrity in multi-DIMM configurations. ECC functionality helps detect and correct memory errors during operation, reducing system instability in production environments.

It is typically deployed in legacy rack and tower servers such as DL, ML, and BL series systems where DDR3 infrastructure is still in service for virtualization, file hosting, and application workloads. The module follows standard 240-pin DIMM architecture for compatibility with supported HPE server generations.

This memory kit is validated for HPE ProLiant platforms and integrates into existing ECC memory channels to maintain balanced performance and system reliability under enterprise usage conditions.

Typical Deployment Scenarios

• HPE ProLiant G6/G7 server upgrades
• Entry-level virtualization hosts
• Legacy enterprise application servers
• File and print server memory expansion
• Small database workload environments
• Branch office infrastructure systems
