1. Ensure that the socket release lever and the CPU cover are in their fully-open position.
2. Unpack the new CPU.

   ---

   Caution - ESD component damage. The CPU is highly sensitive to static electricity. Observe ESD precautions before handling the CPU. See Antistatic Procedures and Precautions.

3. Align the small triangle on the upper-left corner of the CPU with the alignment triangle on the socket.

   In addition, ensure that the alignment post on the socket engages the semicircular cutout on the CPU.

   
   
4. Set the CPU in the socket.

   ---

   Caution - Component and motherboard damage. Do not force the CPU into the socket. The CPU does not need to be pushed downward. When the CPU is correctly aligned, you should be able to easily place the CPU in the socket and it should have minimal movement within the socket. Forcing a misaligned CPU into the socket can permanently damage the component and the motherboard.

5. When the CPU is seated in the socket, close the CPU cover.
6. To secure the CPU in the socket, lower the socket release lever down until it snaps into place under the retaining clip.
7. If you are installing a new heatsink, remove the protective plastic from the base of the heatsink to expose the pre-applied thermal compound and go to Step 10.
8. If you are not installing a new heatsink, use the alcohol pads to remove any residual thermal compound from the bottom of the heatsink.
9. Apply thermal compound to the top of the CPU.

   For best application, use the entire contents of the pre-filled syringe and apply the compound in a star (asterisk) pattern.

10. Carefully position the heatsink over the CPU, aligning it with the mounting posts.

    After the heatsink contacts the CPU, minimize the movement .

    ---

    Caution - If the heatsink is moved too much during its installation, the layer of thermal compound might become uneven, leading to component damage.

11. To secure the heatsink to the motherboard, alternately tighten the four screws.

    Alternately turn each screw one full turn until all the screws are tightened fully.
