How to Install HPE AMD EPYC 7003 7643 Octatetraconta-core (48 Core) 2.30 GHz Processor Upgrade

• Verify compatibility: Confirm your server motherboard and BIOS support the AMD EPYC 7003 family and Socket SP3. Review the motherboard’s Qualified Vendor List (QVL) and firmware requirements before proceeding.
• Power down and prepare: Power off the system, unplug the power cord, and ground yourself to prevent static discharge. Open the server chassis and locate the processor socket area.
• Remove existing cooler and CPU (if upgrading): If replacing an existing CPU, carefully detach the heatsink and fan assembly, disconnecting any cables as needed. Release the CPU retention mechanism and gently lift the old processor from the socket.
• Prepare the new CPU: Hold the EPYC 7643 by the edges, align the notch/triangle marker with the socket alignment marker, and place it into the Socket SP3 socket without forcing. Ensure correct seating with even contact on the socket pins.
• Apply thermal interface material: If your cooler does not have pre-applied thermal paste, apply a thin, even layer of high-quality thermal paste to the CPU heat spreader. Reattach the heatsink/fan assembly securely, ensuring even pressure across all mounting points.
• Reconnect cooling and power: Reconnect all fans and power cables, and reinstall the server cover. Return the server to its rack and power it up.
• Update firmware and BIOS: Enter the system BIOS/UEFI on first boot and apply any recommended firmware or BIOS updates to ensure full compatibility with the EPYC 7003 family. Save changes and reboot as required.
• Verify operation and monitor: During the first boot, check CPU recognition in the BIOS, then boot to the operating system. Run diagnostic and stability tests to confirm proper temperatures, core counts, and thread activity, adjusting cooling and BIOS settings if needed.
