NOTE: If you are installing just one processor, it must be installed in socket CPU1.
1. If applicable, remove the heat-sink blank.
2. Unlatch and rotate the socket-release levers 90 degrees upward and ensure that the socket-release lever is fully
open.
3. Hold the tab near the label marked LIFT on the processor shield and rotate it upward and out of the way.
4. If applicable, remove the socket protective cap from the processor shield. To remove the socket protective cap,
push the cap from the inside of the processor shield and move it away from the socket pins.
NOTE: It is recommended that you install/remove the socket protective cap from the processor shield with
the processor shield in the open position.
CAUTION: Positioning the processor incorrectly can permanently damage the system board or the processor.
Be careful not to bend the pins in the socket.
CAUTION: Do not use force to seat the processor. When the processor is positioned correctly, it engages
easily into the socket.
5. Install the processor in the socket:
a. Identify the pin-1 corner of the processor by locating the tiny gold triangle on one corner of the processor.
Place this corner in the same corner of the ZIF socket identified by a corresponding triangle on the system
board.
b. Align the pin-1 corner of the processor with the pin-1 corner of the system board.
c. Set the processor lightly in the socket.
Because the system uses a ZIF processor socket, do not use force. When the processor is positioned correctly,
it drops down into the socket with minimal pressure.
d. Close the processor shield.
e. Rotate the socket-release lever near the label marked CLOSE 1st until it is locked in position.
f. Similarly, rotate the socket-release lever near the label marked OPEN 1st to the locked position.
CAUTION: Applying too much thermal grease can result in excess grease coming in contact with and
contaminating the processor socket.
6. Install the heat sink:
If you are:
Reinstalling a
heat sink
Use a clean, lint-free cloth to remove the existing thermal grease from the heat sink.
Upgrading a
processor
If a new heat sink was supplied with the processor, install it.
Reinstalling a
processor
Clean any remnants of thermal grease from the processor.
a. Open the grease applicator included with your processor kit and apply all of the thermal grease in the
applicator to the center of the topside of the new processor.
b. Place the heat sink onto the processor.
c. Tighten the four screws to secure the heat sink to the blade board.
NOTE: Do not over-tighten the heat sink retention screws when installing the heat sink. To prevent over-
tightening, tighten the retention screw until resistance is felt, and stop once the screw is seated. The
screw tension should be no more than 6 in-lb (6.9 kg-cm).
7. Install the cooling shroud.
8. Close the blade.
