CPU Socket - 478 Configuration Steps:
1. Locate the CPU socket on your mainboard and nudge the lever away from the socket.
Then lift the lever to a 90-degree angle.
2.On the socket, locate the corner that has the pin-1 receptor. This corner will have a
cut-corner, on the rectangular shaped pattern of pin holes on the socket.
Match the dot on the CPU with the pin-1 receptor on the socket and lower the CPU onto
the socket. The bottom of the CPU should be flush with the face of the socket.
3. Lower the lever until it snaps back into position. This will lock down the CPU.
4. Smear thermal grease on top of the CPU. Lower the CPU fan onto the CPU and use the
clasps on the fan to attach it to the socket. Finally, extend the power cable from the fan
and insert it onto the CPUFAN adapter.
Before starting the system
Please check the installation completely before starting the system.
Verify that the heatsink is properly installed and make sure the CPU fan is
working. Overheating can damage the CPU and other sensitive components.
