4. Setup Instructions
Follow these steps carefully to install your Atermiter X99 AR9 Motherboard Set.
4.1. Preparing Your System
- Ensure your computer case is compatible with Micro-ATX motherboards.
- Gather necessary tools: screwdriver, thermal paste (if not pre-applied to CPU cooler), anti-static wrist strap.
- Ensure you have a power supply of at least 500W from a reputable brand.
4.2. Motherboard Installation
- Carefully place the motherboard into your computer case, aligning the screw holes with the standoffs.
- Secure the motherboard with screws. Do not overtighten.

4.3. CPU Installation (Intel Xeon E5 2680 V4)
- Locate the LGA 2011-3 socket on the motherboard.
- Open the CPU retention mechanism.
- Carefully align the Intel Xeon E5 2680 V4 CPU with the socket, ensuring the gold triangle on the CPU matches the indicator on the socket.
- Gently lower the CPU into the socket without applying force.
- Close the CPU retention mechanism to secure the CPU.
- Install a compatible CPU cooler (not included in this set) on top of the CPU, ensuring proper thermal paste application.

4.4. RAM Installation (DDR4 REG ECC)
- Locate the four DDR4 memory slots on the motherboard.
- Open the clips at both ends of the memory slot.
- Align the notch on the DDR4 REG ECC memory module with the key in the memory slot.
- Insert the memory module firmly into the slot until the clips snap into place. Install both 16GB modules for 32GB total.

4.5. Power Supply Connections
- Connect the 24-pin ATX main power connector from your power supply to the corresponding port on the motherboard.
- Connect the 8-pin (or 4+4-pin) CPU power connector to the CPU power port near the CPU socket.
4.6. Storage and Peripherals
- Storage: Connect your SATA drives to the SATA ports. For M.2 NVMe SSDs, insert them into the M.2 slot and secure with a screw.
- Graphics Card: If using a dedicated graphics card, install it into the PCIe x16 slot and secure it.
- Front Panel Connectors: Connect the front panel USB, audio, power switch, reset switch, and LED indicators to the appropriate headers on the motherboard. Refer to your case manual for specific pin layouts.
- Rear I/O: Connect your monitor, keyboard, mouse, and other peripherals to the back I/O ports (USB, LAN, Audio, PS/2).

5. Operating Instructions
5.1. Initial Power On
- Double-check all connections before powering on the system.
- Connect the power cable to your power supply and turn on the power switch on the PSU.
- Press the power button on your computer case.
- The system should boot up and display the BIOS/UEFI screen or begin loading your operating system.
5.2. BIOS/UEFI Setup
Upon initial boot, you may need to enter the BIOS/UEFI setup to configure settings such as boot order, date/time, and enable specific features. Typically, you can access the BIOS by pressing the 'DEL' or 'F2' key repeatedly during startup.
5.3. Operating System Installation
Once BIOS settings are configured, you can proceed with installing your preferred operating system (e.g., Windows, Linux) from a bootable USB drive or DVD.
6. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your motherboard set.
- Dust Removal: Periodically clean dust from inside your computer case, especially from the CPU cooler, RAM modules, and motherboard surface, using compressed air or a soft brush.
- Cable Management: Ensure cables are neatly routed to improve airflow and prevent obstruction.
- Software Updates: Keep your operating system, drivers, and BIOS/UEFI firmware updated to ensure compatibility and security.
7. Troubleshooting
- No Power/No Boot:
- Ensure all power cables (24-pin ATX, 8-pin CPU) are securely connected.
- Verify your power supply is switched on and functioning correctly.
- Confirm your power supply meets the minimum 500W requirement.
- Display Issues (No Signal):
- Ensure your monitor is connected to the correct graphics output (either integrated or dedicated GPU).
- Reseat the graphics card and RAM modules.
- System Instability/Crashes (Blue Screen):
- Important: The motherboard does not have a temperature control chip. Software-reported temperatures (e.g., 110°-120°C) are virtual and inaccurate. Do NOT attempt to force a temperature sensor device or software, as this can lead to blue screens or system crashes. The actual operating temperature should not exceed 50°C.
- Ensure CPU cooler is properly installed and making good contact.
- Verify RAM modules are correctly seated.
- RAM Speed Display: The Intel Xeon E5-2680V4 CPU natively supports DDR4 up to 1866MHz/2133MHz. While your 3200MHz RAM modules are compatible, the BIOS/system may report them running at 1866MHz or 2133MHz. This is normal behavior due to CPU limitations. CPU-Z software should accurately report the RAM's native 3200MHz speed.
- Motherboard Variations: Due to different production batches, the motherboard's design (e.g., memory slot color, SATA port position, LED backlight presence) may vary slightly from images. These are functional equivalents.
- Sleep Mode: This motherboard does not support sleep mode.
8. User Tips
- Power Supply: Always use a high-quality power supply of at least 500W to ensure stable operation, especially with powerful components like the Xeon E5 CPU.
- RAM Compatibility: Remember that this system uses REG ECC server memory. Do not attempt to mix it with standard desktop RAM, as they are not compatible and will prevent the system from booting.
- CPU/RAM Condition: The CPU and RAM included in this set are used components and may show minor physical scratches or marks. This is normal for refurbished or pre-owned parts and does not affect performance, as all components are thoroughly tested before shipping.
- BIOS Updates: While not always necessary, checking for the latest BIOS updates from the manufacturer (if available) can sometimes improve stability and compatibility.
