1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your Intel Xeon Gold 6138 processor. The Intel Xeon Gold 6138 is a high-performance CPU designed for server and workstation environments, featuring 20 cores, a base frequency of 2.0 GHz, 27.5 MB cache, and support for DDR4-2666 memory. It operates within a 125W Thermal Design Power (TDP) and is compatible with the FCLGA3647 (LGA3647) socket. Please read this manual thoroughly before proceeding with installation.
2. Safety Information
Always observe the following safety precautions when handling and installing your processor:
- Electrostatic Discharge (ESD) Prevention: Processors are sensitive to static electricity. Always wear an anti-static wrist strap and work on an anti-static mat. Avoid touching the gold contacts on the bottom of the processor.
- Power Off: Ensure the system is completely powered off and unplugged from the power source before opening the computer case or handling any internal components.
- Handle with Care: Hold the processor by its edges. Do not drop or apply excessive force to the processor.
- Ventilation: Ensure adequate ventilation in your system to prevent overheating.
- Professional Installation: If you are unsure about any step, consult a qualified technician.
3. Package Contents
Verify that all items are present in your processor package:
- Intel Xeon Gold 6138 Processor
- Installation Guide (this document)
- Note: Thermal solution (heatsink and fan) is typically sold separately for server processors. Ensure you have a compatible thermal solution for LGA3647 sockets.
4. Setup and Installation
Follow these steps carefully to install your Intel Xeon Gold 6138 processor.
4.1 Pre-installation Checklist
- Compatible motherboard with LGA3647 socket.
- Compatible server-grade RAM (DDR4-2666 recommended).
- Appropriate thermal solution (heatsink and fan/liquid cooler) for LGA3647.
- Thermal interface material (TIM), if not pre-applied to the heatsink.
- Anti-static wrist strap and mat.
- Screwdriver (if required for heatsink mounting).
4.2 Processor Installation Steps
- Prepare the System: Power off and unplug your computer. Open the computer case to access the motherboard.
- Prepare the Socket: Locate the LGA3647 socket on your motherboard. Carefully open the socket retention mechanism according to your motherboard's instructions. This typically involves releasing several levers.
- Orient the Processor: The Intel Xeon Gold 6138 processor has specific notches or alignment indicators. Align these with the corresponding keys on the LGA3647 socket. Do not force the processor into the socket. It should sit gently into place.
- Secure the Processor: Once the processor is correctly seated, close the socket retention mechanism. Ensure all levers are securely locked.
- Apply Thermal Paste: If your heatsink does not have pre-applied thermal paste, apply a small amount (pea-sized dot) to the center of the processor's integrated heat spreader (IHS).
- Install Thermal Solution: Carefully place the heatsink onto the processor, aligning it with the mounting holes on the motherboard. Secure the heatsink using the provided screws or clips, tightening them evenly to ensure proper contact and pressure.
- Connect Fan Cables: Connect the heatsink fan cable(s) to the appropriate CPU fan header(s) on the motherboard.
- Close Case and Power On: Close the computer case, reconnect all cables, and power on the system.

5. Operating Considerations
Once installed, the Intel Xeon Gold 6138 processor will be recognized by your system's BIOS/UEFI and operating system.
- BIOS/UEFI Settings: Access your motherboard's BIOS/UEFI to verify processor detection and ensure memory settings (e.g., DDR4-2666) are correctly configured.
- Operating System: Install or update your operating system. Ensure all necessary drivers, especially chipset drivers, are installed for optimal performance.
- Monitoring: Utilize system monitoring tools to keep track of CPU temperature and load, ensuring it operates within safe limits.
- Workload Optimization: For server environments, configure your operating system and applications to leverage the multi-core capabilities of the Xeon Gold 6138.
6. Maintenance
Proper maintenance ensures the longevity and stable performance of your processor.
- Dust Removal: Regularly clean dust from the heatsink fins and fan blades using compressed air. Excessive dust can impede airflow and lead to overheating.
- Thermal Paste Replacement: Over time, thermal paste can dry out. Consider reapplying thermal paste every few years or if you notice increased CPU temperatures.
- System Cooling: Ensure all system fans are functioning correctly and that the computer case has adequate airflow.
- Software Updates: Keep your operating system and motherboard BIOS/UEFI updated to benefit from performance improvements and bug fixes.
7. Troubleshooting
If you encounter issues, refer to the following common troubleshooting steps:
- System Fails to Boot:
- Double-check all power connections, especially the CPU power connector.
- Ensure the processor is correctly seated in its socket and the retention mechanism is locked.
- Verify that RAM modules are properly installed in their slots.
- Check for any bent pins on the motherboard socket (if applicable, though LGA3647 is land grid array).
- Overheating Issues:
- Confirm the heatsink is properly mounted and making good contact with the CPU.
- Ensure thermal paste was applied correctly.
- Check if the CPU fan is spinning and connected to the correct header.
- Clean any dust from the heatsink and case fans.
- System Instability/Crashes:
- Update motherboard BIOS/UEFI to the latest version.
- Run memory diagnostic tools to check for RAM issues.
- Ensure your power supply unit (PSU) provides sufficient wattage for all components.
