4. Setup Instructions
4.1 Before You Begin
- Ensure you have all necessary components: CPU, CPU cooler, RAM, storage devices (SSD/HDD), power supply, and a compatible PC case.
- Work on a clean, flat, and static-free surface. Use an anti-static wrist strap or frequently touch a grounded metal object to discharge static electricity.
- Refer to your PC case manual for specific mounting instructions.
4.2 Motherboard Installation
- Prepare the Case: Install the I/O shield into the rear opening of your PC case. Install standoffs in the case according to the motherboard's mounting holes.
- Install the CPU: Open the CPU socket retention lever. Carefully align the CPU with the socket, ensuring the golden triangle on the CPU matches the triangle on the socket. Gently place the CPU into the socket without forcing it. Close the retention lever to secure the CPU.
- Install the CPU Cooler: Apply thermal paste to the CPU if not pre-applied on the cooler. Mount the CPU cooler according to its instructions, ensuring it is securely fastened and makes good contact with the CPU. Connect the CPU fan cable to the 'CPU_FAN' header on the motherboard.
- Install RAM: Open the clips on the DDR4 memory slots. Align the RAM module with the slot, ensuring the notch on the module matches the key in the slot. Press down firmly on both ends of the module until the clips snap into place. For optimal performance, install RAM in the recommended dual-channel or quad-channel configuration as per the motherboard's silkscreen or manual.
- Install Storage Devices:
- M.2 SSD: Insert the M.2 SSD into the appropriate M.2 slot (NVME M.2 or SATA M.2) at an angle, then gently push it down and secure it with the provided screw.
- SATA Drives: Connect SATA data cables from your SSDs/HDDs to the SATA ports on the motherboard.
- Mount the Motherboard: Carefully place the motherboard into the PC case, aligning the screw holes with the installed standoffs. Secure the motherboard with screws.
- Connect Power Supply: Connect the 24-pin ATX power cable from your power supply to the main 24-pin power connector on the motherboard. Connect the 8-pin (or 4+4-pin) CPU power cable to the 8-pin CPU power connector. Connect SATA power cables to your storage drives.
- Connect Front Panel Cables: Connect the power button, reset button, HDD LED, power LED, and USB/audio headers from your PC case to the corresponding pins on the motherboard's front panel header. Refer to the motherboard layout diagram (Figure 2.2.1) for pin locations.
- Install Expansion Cards: Insert graphics cards or other PCIe expansion cards into the appropriate PCIe slots and secure them with the case's retention mechanism.
5. Operating the Motherboard
5.1 First Boot and BIOS/UEFI Setup
After completing the hardware installation, connect your monitor, keyboard, and mouse. Power on your system.
- During the boot process, repeatedly press the DEL or F2 key (or as indicated on screen) to enter the BIOS/UEFI setup utility.
- In the BIOS/UEFI, you can configure boot order, system time, fan speeds, and other hardware settings. Ensure your storage drive is recognized and set as the primary boot device for OS installation.
- Save changes and exit the BIOS/UEFI. The system will restart.
5.2 Operating System and Driver Installation
- Insert your operating system installation media (USB drive or DVD) and follow the on-screen prompts to install your preferred OS.
- After OS installation, install the necessary drivers for your motherboard's components (chipset, LAN, audio, USB, etc.). These drivers are typically available on the manufacturer's website or included on a driver CD/USB drive with the motherboard.
