How to install HPE Intel Xeon Platinum 8558P Octatetraconta-core Processor Upgrade

• Prepare the server and verify compatibility: Confirm that your HP server motherboard supports the LGA-4677 socket and that the BIOS/firmware is compatible with Intel Xeon Platinum 5th Gen processors. Check HP’s hardware compatibility guides and ensure you have the proper cooling solution capable of handling a 350 W TDP part.
• Power down and ground yourself: Shut down the server, unplug all power sources, and discharge static from your body or workstation using an anti-static strap to protect sensitive components.
• Access the CPU socket and remove the existing processor: Open the CPU socket lever, carefully lift the heatsink if present, and remove the current processor while keeping the socket pins or land patterns undamaged. Inspect for any bent pins or debris and clean as needed following the manufacturer’s guidelines.
• Install the new processor: Align the 8558P with the socket using the alignment notches and seating grooves. Gently lower the CPU into the socket, ensuring even contact. Secure the socket lever to lock the processor in place, following the server’s service manual for proper torque and seating.
• Apply cooling and thermal interface material if required: Install an appropriate server-grade heatsink/cooler and apply a thin, even layer of thermal interface material as recommended by the cooling solution’s manufacturer. Ensure proper clearance and airflow to manage the 350 W TDP effectively.
• Update firmware and BIOS: Power on the server and enter BIOS/UEFI to verify CPU recognition. Install any recommended microcode updates, BIOS patches, and firmware updates to ensure full compatibility and optimization for the 8558P.
• Test and validate: Boot into the operating system and perform a basic stability check. Run stress tests and monitor CPU temperatures and power consumption to confirm stable operation under load. Validate that virtualization, databases, or HPC workloads run as expected.
