How to install HPE AMD EPYC 7643P Octatetraconta-core Processor Upgrade

• Power down the server, unplug all cables, and ground yourself to prevent static discharge.
• Open the server chassis and locate the processor heatsink/fan assembly for the corresponding CPU socket (SP3).
• Remove the existing CPU module according to the server’s maintenance procedures, and carefully clean any residual thermal paste from the heatsink contact surface.
• Align the EPYC 7643P with the SP3 socket using the standard alignment notches, then gently seat the processor into place until it is fully seated.
• Apply a fresh, thin layer of high-quality thermal paste if required, reseat the heatsink/fan assembly, and secure all mounting hardware.
• Reassemble the server, reconnect power, and perform a BIOS update to ensure compatibility with the new CPU and to enable the latest microcode features.
• Power on, enter the BIOS/UEFI, and verify that the new processor is detected, then configure NUMA and memory settings if applicable for optimal performance.
• Boot into the operating system and monitor CPU frequency, core utilization, and thermal headroom to confirm stable performance under load.
