Make sure not to bend or break any pins on the back. Hardware Installation Close the load plate over the CPU and press down while you close and engage the socket lever. Installing the CPU Fan There are many different fan types that can be used with this motherboard. Follow the instruction that came with you fan assembly. Be sure that the fan orientation is correct for your chassis type and your fan assembly. XFX nForce 780i 3-Way SLI Motherboard Use the following procedure to install memory DIMMs. Note that there is only one gap near the center of the DIMM slot.

This slot matches the slot on the memory DIMM to ensure the component is installed properly. Hardware Installation Securing the Motherboard into the Chassis Most computer chassis have a base with mounting studs or spacers to allow the mother board to be secured to the chassis and help to prevent short circuits. If there are studs that do not align with a mounting hole on the motherboard, it is recommended that you remove that stud to prevent the possibility of a short circuit.
