DDR2 PC2-5300 Technology

Running at 667MHz, the 408855-B21 delivers stable and efficient data transfer speeds through its DDR2 PC2-5300 technology. While DDR2 memory may be a legacy solution, it remains a reliable and effective option for enterprises operating HP servers built for DDR2 architecture.

This module ensures servers run at consistent performance levels, minimizing bottlenecks that often occur with lower-capacity memory setups. For legacy systems that still play a critical role in operations, the 408855-B21 is an essential upgrade that brings measurable improvements.

ECC (Error-Correcting Code) for Data Integrity

One of the core features of the 408855-B21 is its ECC (Error-Correcting Code) support. ECC technology automatically detects and corrects memory errors, ensuring accurate data processing and reducing the risk of crashes or corrupted files.

For mission-critical industries such as healthcare, finance, and IT services, error prevention is non-negotiable. The 408855-B21 offers peace of mind by guaranteeing data integrity and ensuring that enterprise applications run smoothly without interruptions caused by memory errors.

Registered DIMM for Enterprise Stability

The 408855-B21 is a Registered DIMM (RDIMM), meaning it includes an extra register that buffers signals between the memory controller and the DRAM. This design reduces the electrical load on the memory controller, allowing servers to support more DIMMs while maintaining stability.

RDIMMs are especially valuable in environments where high performance and scalability are necessary. With the 408855-B21, businesses benefit from greater reliability even under heavy workloads, making it a strong fit for enterprise-grade systems.

HP-Certified Quality and Compatibility

As an HP-certified memory module, the 408855-B21 undergoes extensive testing to ensure flawless compatibility with HP servers. Using certified memory ensures long-term system stability and removes the risk of performance issues often seen with non-certified modules.

Choosing the 408855-B21 guarantees seamless integration with HP server models, extending the system’s operational lifespan and supporting maximum uptime. This reliability makes it a smart choice for organizations prioritizing stability and compatibility.

Cost-Effective IT Upgrade

Upgrading with the 408855-B21 offers an affordable way to extend the value of existing HP servers. Instead of replacing entire systems, IT teams can upgrade memory to enhance server performance, support growing workloads, and optimize resources.

The 408855-B21 is a cost-efficient option that delivers enterprise-class performance while protecting prior investments in infrastructure.
