If the release lever on the socket is not fully extended, move it to that
position.
NOTICE: Socket pins are delicate. To avoid damage, ensure that the processor is aligned properly with the socket, and do not use excessive force when you install the processor. Be careful not to touch or bend the pins on the system board.
NOTICE: You must position the processor correctly in the socket to avoid permanent damage to the processor.
Orient the front and rear alignment notches on the processor with the
front and rear alignment notches on the socket.
Align the pin-1 corners of the processor and socket.
Place the processor lightly in the socket and ensure that the processor is
positioned correctly.
When the processor is fully seated in the socket, close the processor cover.
Ensure that the tab on the processor cover is positioned underneath the center cover latch on the socket.
Pivot the socket release lever back towards the socket, and snap it into
place to secure the processor.
Clean the thermal grease from the bottom of the heat sink.
NOTICE: Ensure that you apply new thermal grease. New thermal grease is critical for ensuring adequate thermal bonding, which is a requirement for optimal processor operation.
Apply the new thermal grease to the top of the processor.
NOTICE: Ensure that the processor heat sink assembly is correctly seated and secure.
