2.4 Expansion Card Installation
The motherboard includes two PCI-Express 2.0 x16 slots (supporting ATI CrossFireX), one PCI-Express 2.0 x1 slot, and three PCI slots.
- Select an appropriate expansion slot for your card (e.g., graphics card in a PCIe x16 slot).
- Remove the corresponding slot cover from your computer case.
- Align the card with the slot and press down firmly until it is seated.
- Secure the card with a screw to the case.

3. Operating Instructions
After successful hardware installation, proceed with system startup and software configuration.
3.1 Initial Power On and BIOS Setup
- Connect your monitor, keyboard, and mouse.
- Power on your computer.
- Press the DEL key during startup to enter the BIOS setup utility.
- Configure essential settings such as boot order, date, and time.
- Explore advanced features like Core Unlocker and TurboV EVO for performance tuning, if desired. Refer to the BIOS utility for detailed explanations of each setting.
- Save changes and exit the BIOS.
3.2 Operating System Installation
Install your preferred operating system (e.g., Windows 10) from a bootable USB drive or optical disc.
3.3 Driver Installation
Install the necessary drivers for the motherboard components, including chipset, LAN, audio, and USB 3.0 drivers. These are typically provided on a support DVD or available for download from the ASUS website.
4. Maintenance
Regular maintenance helps ensure the longevity and stability of your motherboard.
- Dust Removal: Periodically clean dust from the motherboard and components using compressed air. Ensure the system is powered off and unplugged before cleaning.
- BIOS Updates: Check the ASUS support website for the latest BIOS updates. Updating the BIOS can improve compatibility and system stability. Follow the instructions provided by ASUS carefully during the update process.
- Component Checks: Ensure all cables and components are securely seated. Loose connections can lead to intermittent issues.
5. Troubleshooting
This section addresses common issues you might encounter.
- System Does Not Power On:
- Verify all power supply connections to the motherboard (24-pin ATX and 4-pin ATX 12V).
- Ensure the power supply unit is switched on.
- Check front panel power switch connections to the motherboard.
- No Display Output:
- Ensure the graphics card is properly seated in its PCIe slot and has adequate power.
- Check monitor connections and ensure the monitor is powered on and set to the correct input.
- If using integrated graphics (if available on your CPU/APU, though this board requires a discrete GPU), ensure the display cable is connected to the motherboard's video output.
- Memory (RAM) Issues:
- The motherboard features a DRAM LED that illuminates if there is an issue with memory detection.
- Reseat memory modules firmly in their slots.
- Test with one memory module at a time to identify a faulty stick or slot.
- Operating System Instability:
- Ensure all drivers are correctly installed and up to date.
- Check for overheating issues by monitoring CPU and chipset temperatures.
- Run memory diagnostic tools to check for RAM errors.
- USB Ports Remain Powered After Shutdown:
- This is a known characteristic for some configurations. To fully power off USB devices, either toggle the power supply switch off and on, or unplug and replug the power cable from the wall.
