3. Setup Guide

Follow these steps carefully for proper installation of your motherboard and components.

3.1. CPU Installation

1. Locate the LGA 1700 CPU socket on the motherboard.
2. Gently push down the load lever and pull it to the side to open the CPU socket retention frame.
3. Align the triangular mark on the CPU with the corresponding mark on the socket. Carefully place the CPU into the socket, ensuring it sits flat without force.
4. Close the retention frame and push the load lever back into its locked position.

Note: Handle the CPU by its edges only. Avoid touching the gold contacts or the socket pins.

3.2. RAM (DDR4) Installation

1. Identify the four DDR4 DIMM slots. For dual-channel operation, refer to the motherboard manual for specific slot pairing (usually slots 2 and 4).
2. Open the clips at both ends of the DIMM slot.
3. Align the notch on the DDR4 memory module with the key in the DIMM slot.
4. Press down firmly on both ends of the memory module until the clips snap into place.

3.3. Storage Device Installation (M.2 and SATA)

3.3.1. M.2 SSD Installation

1. Locate the M.2 slots on the motherboard. This board supports multiple M.2 slots, including one with PCIe 4.0 x4 support.
2. Remove the M.2 heatsink (if present) and the standoff screw from the desired M.2 slot.
3. Insert the M.2 SSD into the slot at a 30-degree angle.
4. Gently push the SSD down and secure it with the standoff screw. Reattach the M.2 heatsink if applicable.

3.3.2. SATA Drive Installation

1. Connect one end of a SATA data cable to a SATA port on the motherboard.
2. Connect the other end of the SATA data cable to your SATA HDD/SSD.
3. Connect a SATA power cable from your power supply unit (PSU) to the SATA drive.

3.4. PCIe Device Installation (Graphics Card, etc.)

1. Locate the PCIe 5.0 x16 slot for your graphics card.
2. Open the retention clip at the end of the PCIe slot.
3. Align your graphics card with the slot and press down firmly until it clicks into place and the retention clip closes.
4. Secure the graphics card to your PC case with screws.
5. Connect any necessary PCIe power cables from your PSU to the graphics card.

3.5. Power Connections

• 24-pin ATX Power Connector: Connect the main 24-pin power cable from your PSU to the corresponding connector on the motherboard.
• 8-pin CPU Power Connector: Connect the 8-pin (or 4+4 pin) CPU power cable from your PSU to the connector near the CPU socket.

3.6. Front Panel Connections

Connect the cables from your PC case (Power Button, Reset Button, HDD LED, Power LED, USB, Audio) to the corresponding headers on the motherboard. Refer to the motherboard's detailed diagram for exact pin assignments.

4. Operating Instructions
