HPE P19041-B21

Overview

The HPE P19041-B21 is a 16GB DDR4 SmartMemory module designed to enhance the performance and reliability of HPE ProLiant Gen10 servers. Operating at 2933 MHz, it accelerates data transfer between the processor and memory, making it well suited for demanding workloads such as virtualization, database management, and analytics. This registered DIMM features error-correcting code to maintain data integrity and reduce system errors, ensuring stable operation in critical environments.

Key features

• Memory module certified and optimized for HPE ProLiant Gen10 servers, ensuring seamless integration and firmware compatibility
• Error-correcting code (ECC) that detects and corrects common memory errors to prevent application disruptions
• Registered DIMM design that reduces electrical load on the memory controller, supporting multi-module configurations and heavy multitasking
• Single-rank configuration that streamlines memory access for consistent and predictable response times
• Low voltage operation at 1.2 volts to help manage power consumption in dense server racks and compact environments
• Standard 288-pin form factor that fits easily into compatible server memory slots without modification
• CAS latency of 21, balancing speed and stability for reliable performance under load

Performance and reliability

This memory module is engineered to deliver consistent performance in enterprise server environments. The built-in ECC technology safeguards data integrity by automatically correcting errors before they impact system stability. Its registered DIMM architecture helps maintain signal quality and reduces electrical stress on the memory controller, which is especially important when multiple modules are installed. These features combine to minimize downtime and support continuous operation for mission-critical applications.

Ideal uses and environments

The HPE P19041-B21 is a strong choice for IT administrators managing branch office servers, cloud infrastructure, or test labs that require additional memory capacity without a full system upgrade. It fits well in setups where reliable, high-speed memory access is essential to handle virtualization, database transactions, or analytics workloads. Its low power consumption also makes it suitable for environments where energy efficiency is a priority.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
