3. Setup Guide

Follow these steps for proper installation of your Dpofirs X99 Motherboard CPU Combo:

3.1 CPU Installation

1. Prepare the Socket: Gently lift the CPU socket lever to open the retention mechanism.
2. Align the CPU: Carefully align the Intel Xeon E5 2620 V3 CPU with the LGA 2011-3 socket. Ensure the CPU notch corresponds to the bump on the CPU base and the triangle logo on the CPU aligns with the #1 position on the motherboard's CPU chassis silkscreen.
3. Insert the CPU: Place the CPU gently into the socket without forcing it. If it does not sit correctly, re-check alignment.
4. Secure the CPU: Lower the socket lever and push it down until it locks into place, securing the CPU.
5. Install CPU Cooler: Apply thermal paste (if not pre-applied) and install a compatible CPU cooler. Ensure it is securely mounted to prevent overheating.

WARNING: Incorrect CPU installation can damage the CPU pins and motherboard, leading to system failure. Such damage may void your warranty.

3.2 RAM Installation

1. Open DIMM Slots: Open the clips at both ends of the DDR4 DIMM slots.
2. Align RAM Modules: Align the notch on the DDR4 memory module with the key in the DIMM slot.
3. Insert RAM: Insert the memory module firmly into the slot until the clips snap into place. Ensure both clips are closed.
4. Check Compatibility: For optimal performance and stability, refer to the Qualified Vendor List (QVL) on the Dpofirs website to ensure your RAM modules are certified to work with this motherboard.

3.3 Power Connections

1. 24-pin ATX Power: Connect the 24-pin ATX power cable from your power supply unit (PSU) to the corresponding connector on the motherboard.
2. 8-pin CPU Power: Connect the 8-pin CPU power cable from your PSU to the 8-pin connector near the CPU socket. Both 24-pin and 8-pin power connectors must be connected simultaneously for the motherboard to function.

3.4 Peripheral Connections

1. Storage Devices: Connect your NVME M.2 SSDs to the M.2 interface and SATA hard drives/SSDs to the SATA3.0 ports using SATA cables.
2. Front Panel Connectors: Connect the power button, reset button, HDD LED, and power LED cables from your PC case to the corresponding pins on the motherboard's front panel header.
3. USB and Audio: Connect front panel USB and audio cables to their respective headers on the motherboard.
4. Graphics Card: If using a discrete graphics card, install it into a PCIe X16 slot and connect the necessary power cables from the PSU.
5. Monitor: Connect your monitor to the graphics card (if discrete) or the motherboard's integrated graphics output (if your CPU supports it).

4. Operating Instructions

After completing the hardware installation, you can proceed with initial system boot-up.

4.1 Initial Boot-Up

1. Power On: Press the power button on your PC case.
2. First Boot Delay: The first boot may take 3-5 minutes as the motherboard reads RAM information. Please wait patiently.
3. BIOS Access: To enter the BIOS setup, press the DEL or ESC key during boot. For a one-time boot menu, press F11.
4. Q-Code Display: The digital status display (Q-code) will show various codes during boot. Once the system boots and stabilizes, "AA" typically indicates normal operation.

5. Maintenance

Proper maintenance ensures the longevity and optimal performance of your motherboard.

• Keep Clean: Regularly clean dust from the motherboard and components using compressed air. Ensure the system is powered off and unplugged before cleaning.
• Ensure Airflow: Maintain good airflow within your PC case to prevent overheating. Ensure all fans are functioning correctly.
• BIOS Updates: Periodically check the Dpofirs website for BIOS updates to improve compatibility and performance.

6. Troubleshooting

If you encounter issues, refer to the following troubleshooting steps:

6.1 System Fails to Power On

1. Check CPU Installation: Verify that the CPU is correctly installed in the socket, with proper alignment and no bent pins.
2. Check RAM: Ensure RAM modules are fully seated in their slots. If the motherboard alarms (beeps) without RAM, it indicates the motherboard is functioning. If it still won't turn on, try removing all RAM modules and powering on to check for an alarm.
3. RAM Compatibility: Confirm that your RAM is compatible with the motherboard by checking the Dpofirs Qualified Vendor List (QVL). Ensure RAM gold fingers are not oxidized and memory slots are free of dust.
4. Power Connections: Double-check that both the 24-pin ATX and 8-pin CPU power connectors are securely plugged into the motherboard.
5. CMOS Reset: If the system does not boot or displays unusual behavior, try resetting the CMOS. To do this, remove power from the machine, set the CMOS jumper to pins 2&3 for about 15 seconds, then return the jumper to 1&2, and power back on.

6.2 Overheating Issues

• CPU Cooler: Ensure your CPU cooler is properly installed and making good contact with the CPU. Verify that the fan is spinning.
• Thermal Paste: Check if thermal paste was correctly applied between the CPU and cooler.
• Case Airflow: Ensure adequate airflow within your PC case. Clean any dust buildup in fans or vents.
