CPU Orientation

Gold Mark

A CPU has a mark (usually a notch or a gold mark) on one corner to help you identify the correct orientation when inserting it to the socket.

Match the marked corner of the CPU to Pin 1 on the socket.

CAUTION

Incorrect installation of the CPU into the socket may bend the pins and severely damage the CPU!
