5. Power Connections
Connect the 24-pin ATX main power connector, and the 8-pin and 4-pin EPS 12V CPU power connectors from your power supply to the motherboard.
6. Front Panel and I/O Connections
Connect your case's front panel headers (power button, reset button, USB ports, audio jacks) to the corresponding pins on the motherboard. The motherboard features an integrated I/O Shield for simplified installation and a comprehensive set of rear I/O ports including USB4 Type-C with DP Alt, USB 3.2 Gen 2, USB 3.2 Gen 1, 5 GbE LAN, and WiFi 7 antenna connectors.

Operating Instructions
1. Initial Boot and BIOS/UEFI Setup
Upon first power-on, press the designated key (usually DEL or F2) during the boot sequence to enter the BIOS/UEFI setup utility. Here you can configure system settings, boot order, and enable features like AMD EXPO for memory optimization.
2. Driver Installation
After installing your operating system, install the necessary drivers for the chipset, LAN, audio, and other components. These drivers are typically provided on a support DVD or available for download from the GIGABYTE website.
3. AI Overclocking (AORUS AI Snatch)
The motherboard features AORUS AI Snatch for intelligent overclocking. This function can automatically optimize CPU and memory performance based on system conditions. Consult the GIGABYTE software utility guide for detailed usage.
Maintenance
1. BIOS Updates
Regularly check the GIGABYTE website for BIOS updates. BIOS updates can improve system stability, compatibility, and performance. When updating the BIOS, use a small capacity USB drive (typically 32GB or less, formatted to FAT32) for the Q-Flash utility. Follow the instructions provided with the BIOS update file carefully.
2. Cleaning
Periodically clean your computer's interior to prevent dust buildup, which can lead to overheating and reduced performance. Use compressed air to remove dust from heatsinks, fans, and other components. Ensure the system is powered off and unplugged before cleaning.
3. Component Checks
Occasionally inspect all cable connections (power, data, and peripheral) to ensure they are secure. Verify that all expansion cards and memory modules are properly seated in their slots.
Troubleshooting
If you encounter issues, consider the following common troubleshooting steps:
- No Power/No Boot: Double-check all power connections to the motherboard and components. Ensure the power supply is functioning correctly.
- Display Issues: Verify that your graphics card is properly seated and connected to the monitor. If using integrated graphics, ensure your monitor is connected to the motherboard's video output.
- Memory Instability: If experiencing crashes or boot failures related to memory, try reseating the RAM modules. Ensure memory is installed in the correct slots according to the manual for dual-channel operation. Adjusting memory frequency or timings in BIOS may be necessary if using high-speed kits.
- Peripheral Not Detected: Check USB or SATA connections. Ensure drivers for the peripheral are installed.
- Clear CMOS: If system settings become unstable or you cannot access BIOS, use the Clear CMOS button on the rear I/O panel or the designated jumper on the motherboard to reset BIOS settings to default.
For more advanced troubleshooting, refer to the comprehensive manual available on the GIGABYTE support website or contact technical support.
