Experience enterprise-grade computing with the HPE Intel Xeon Gold (4th Gen) 6403N Processor Upgrade. This 24-core, 48-thread powerhouse is engineered for data centers, virtualization clusters, and mission-critical workloads that demand consistent throughput and reliable performance. Built on Intel’s 4th Generation Xeon Gold architecture, the 6403N delivers a robust balance of raw multi-core power and efficient turbo performance, making it an ideal upgrade for HP servers seeking to extend lifecycle, maximize consolidation density, and accelerate workloads without a full system replacement. With a base clock of 1.90 GHz and a turbo speed up to 3.60 GHz, this CPU is designed to handle heavy multi-threaded tasks while maintaining solid efficiency in steady-state operation. The 45 MB L3 cache reduces memory latency for data-intensive applications, keeping frequently accessed data close to the CPU cores for improved responsiveness. The LGA-4677 socket compatibility ensures a streamlined upgrade path for compatible HP server boards, while a 185 W TDP supports sustained performance under load. In short, the 6403N is built to deliver dependable performance per watt in data-center environments that require scalable processing power, virtualization efficiency, and resilient operation.

  • High-core density for multi-threaded workloads: With 24 cores and 48 threads, this Xeon Gold processor accelerates virtualization, database analytics, ERP, and other demanding server applications, enabling higher user concurrency and smoother data processing.
  • Strong turbo performance and responsive bursts: The combination of a 1.90 GHz base clock and up to 3.60 GHz turbo frequency provides rapid bursts for short, latency-sensitive tasks while maintaining efficiency during steady-state operation.
  • Large L3 cache for lower latency: A 45 MB L3 cache helps minimize memory bottlenecks, boosting performance for cache-hungry workloads like in-memory databases, large-scale simulations, and data warehousing.
  • Enterprise-ready reliability and compatibility: Designed for the LGA-4677 socket and HP server ecosystems, this upgrade supports 64-bit processing, robust error detection, and scalable enterprise features appropriate for data centers.
  • Power and efficiency tailored for data centers: With an 185 W TDP, the 6403N is optimized for sustained performance in server racks, balancing thermal output with workload demands and cooling capabilities.

How to install HPE Xeon Gold (4th Gen) 6403N

  • Power down the server completely, unplug the power cables, and ground yourself to dissipate any static electricity before handling components.
  • Remove the server chassis cover and locate the CPU socket area on the motherboard that supports the LGA-4677 socket configuration.
  • Carefully release the socket lever, verify the socket alignment, and cautiously seat the 6403N into the LGA-4677 socket with the correct orientation.
  • Secure the socket lever, then install or re-seat the cooling solution (heatsink and fan assembly) with appropriate thermal interface material as required by your HP platform.
  • Reconnect power, boot the system, and enter the BIOS/UEFI to confirm CPU recognition. Enable relevant features such as virtualization and ECC memory where supported by the motherboard.
  • Update firmware and microcode as recommended by HP to ensure compatibility with the Xeon Gold 4th Gen ecosystem and to maximize stability under load.
  • Perform a controlled burn-in test and monitor temperatures and power delivery to verify safe operation and sustained performance in production workloads.

Frequently asked questions

  • Q: What workloads is the HPE Xeon Gold 6403N best suited for?
    A: The 24-core, 48-thread design excels in virtualization, multi-user databases, large-scale analytics, and consolidation scenarios where parallel processing and reliability are essential in data-center environments.
  • Q: Is this processor compatible with HP servers that use the LGA-4677 socket?
    A: Yes. The 6403N is designed for systems that support the LGA-4677 socket within the Xeon Gold (4th Gen) family and HP’s platform certifications. Always verify motherboard compatibility with HP’s service and support documentation for your specific server model.
  • Q: Does the 3.60 GHz turbo frequency indicate guaranteed overclocking?
    A: The 3.60 GHz figure represents turbo/maximum boost frequency under thermal and power limits. Enterprise servers typically rely on firmware-controlled turbo behavior rather than user-driven overclocking, and platform-specific constraints apply.
  • Q: Does this CPU support ECC memory?
    A: Xeon Gold processors traditionally support ECC memory when paired with a compatible server motherboard. Confirm ECC support and memory configuration requirements with your HP server documentation and BMC/BIOS settings.
  • Q: What should I check before upgrading?
    A: Check socket compatibility (LGA-4677), BIOS/firmware support for 4th Gen Xeon Gold, the server’s cooling capacity, and the platform’s memory configuration guidelines. Also confirm warranty terms and any prerequisites related to HP service contracts.
  • Q: Is there anything special about installing this upgrade on HP servers?
    A: HP platform-specific installation guidelines, firmware updates, and HP-certified cooling solutions should be followed. It’s advisable to consult HP’s compatibility matrix and service documentation to ensure a smooth, supported upgrade path.
