4.3. RAM (Memory) Installation

1. Open the clips at both ends of the DDR4 memory slots.
2. Align the notch on your DDR4 memory module with the notch in the DIMM slot.
3. Press down firmly on both ends of the memory module until the clips snap into place.
4. Repeat for additional memory modules, ensuring they are installed in the correct slots for dual-channel operation (refer to motherboard diagram or specific CPU cooler clearance).

4.4. M.2 NVMe SSD Installation

1. Locate the M.2 slot on the motherboard.
2. Remove the small screw and standoff from the M.2 slot.
3. Insert the M.2 NVMe SSD into the slot at an angle.
4. Gently push the SSD down until it is parallel with the motherboard.
5. Secure the SSD with the screw and standoff.

4.5. Motherboard Installation into Case

1. Install the I/O shield into the rear opening of your computer case.
2. Carefully place the motherboard into the case, aligning the screw holes with the standoffs.
3. Secure the motherboard with screws. Do not overtighten.

4.6. Connecting Peripherals and Power
