HPE 826862-B21

Overview

The HPE 826862-B21 is a processor upgrade kit designed for HPE ProLiant DL380 and DL388 Gen10 servers, featuring the Intel Xeon Gold 6126 CPU. This twelve-core processor runs at a 2.6 GHz base frequency and includes 19.25 MB of Level 3 cache, delivering enhanced parallel processing power for demanding server workloads. The kit also includes a compatible heatsink and two standard fan modules to ensure effective cooling and maintain stable performance under heavy use.

Key features

• Twelve-core Intel Xeon Gold 6126 processor that boosts multi-threaded performance for virtualization and database tasks
• Large 19.25 MB Level 3 cache reduces latency by keeping frequently accessed data close to the cores
• 125 W thermal design power supports sustained high-demand workloads without overheating
• Comes with a matching heatsink and two fan modules to provide proper cooling and maintain system reliability
• Directly compatible with the FCLGA 3647 socket on HPE ProLiant DL380 and DL388 Gen10 servers, simplifying installation
• Improves server capacity for hosting virtual machines, running large applications, and accelerating analytics jobs

Installation and setup

Installation is straightforward for technicians familiar with HPE Gen10 ProLiant servers. The processor fits directly into the existing FCLGA 3647 socket on DL380 and DL388 Gen10 motherboards, requiring no additional adapters or specialized tools. The included heatsink and fan modules ensure the processor remains within optimal temperature ranges, supporting reliable operation from the moment it is installed.

Ideal uses and environments

This upgrade kit is well suited for data centers and lab environments that demand flexible and scalable compute power. It enhances virtualization clusters by increasing VM density without oversubscription, supports database servers with faster data access, and accelerates containerized microservices development. Teams running analytics workloads will benefit from quicker query completion and improved resource availability for subsequent tasks.

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.
