2. Setup and Installation

2.1 Component Installation

Before installing the motherboard into your PC case, install the CPU, CPU cooler, and RAM modules.

• CPU Installation: Open the LGA 1200 socket lever, align the triangular mark on the CPU with the mark on the socket, gently place the CPU, and close the lever to secure it.
• RAM Installation: Open the clips on the DDR4 DIMM slots. Align the notch on the RAM module with the key in the slot. Press down firmly on both ends of the module until the clips snap into place. This motherboard supports DDR4 memory up to 128 GB.
• M.2 SSD Installation: Locate the M.2 slot. Insert the M.2 SSD at an angle and then gently push it down, securing it with the provided screw.
• SATA Devices: Connect SATA data cables from your storage drives (HDDs/SSDs) to the SATA 6Gb/s ports on the motherboard.

5. Troubleshooting

If you encounter issues with your motherboard, consider the following troubleshooting steps:

• No Power/No POST: Ensure all power cables (24-pin ATX, 8-pin CPU) are securely connected. Verify the PSU is functioning correctly. Try reseating RAM modules and expansion cards.
• Boot Issues: Check boot order in BIOS. Ensure storage drives are properly connected and detected. Reinstall the operating system if necessary.
• Peripheral Detection: If a device (e.g., USB drive, PCIe card) is not detected, try connecting it to a different port or slot. Ensure drivers are installed.
• System Instability: Check CPU and GPU temperatures. Ensure adequate cooling. Verify RAM stability using memory diagnostic tools.
• Clear CMOS: If system settings become corrupted or you cannot boot, clear the CMOS by either removing the CMOS battery for a few minutes (with power off) or using the CLRTC jumper on the motherboard.

For persistent issues, refer to the comprehensive troubleshooting guide on the official ASUS support website or contact ASUS customer support.
