Overview

The HP 619488-B21 is a 4GB DDR3 SDRAM memory module designed as a genuine HP replacement or upgrade part for compatible ProLiant server and workstation systems. As an HP-qualified component, it has been tested and validated to work seamlessly within supported hardware, reducing the risk of compatibility issues that can arise with third-party alternatives. The single 4GB DIMM form factor makes it a practical choice for incremental memory upgrades while preserving open slots for future expansion.

This module uses DDR3 SDRAM technology, which, while not the latest generation, remains the standard for a large installed base of enterprise servers still in active service. For organizations maintaining or extending the life of existing HP infrastructure, the 619488-B21 offers a reliable and cost-effective way to add capacity without replacing the entire system. It is best suited for environments where moderate memory increases can improve application responsiveness and multitasking performance on supported hardware.
