CPU Installation

Unscrew the captive screw to open the CPU socket frame.
Note: The CPU backplate and CPU socket are pre-installed and are not removable parts.
Remove the pre-installed plastic cover.
Insert CPU into CPU socket by aligning the A1 corner of the CPU with the A1 corner of the socket.
Warning: The pins of the CPU are extremely fragile. Be very careful when installing.
Figure 1.
Close the CPU socket frame and torque captive screw to 13.8 kgf-cm (12 in-lbf).
Remove plastic protective cover from bottom of heatsink.
Ensure the thermal grease is evenly spread across the base of the heat sink.
Align the CPU heatsink over the CPU socket and set it in place.
CAUTION: Be sure the heatsink is aligned properly with the system airflow. Failure to do so may cause system to overheat, possibly causing system damage.
Figure 2.
Insert all six screws and carefully engage the threads. Do not torque to final specifications until all six screws are started.
Using a Torx T20 bit driver, adjust the screwdriver torque setting to 12.5~15.0 kgf-cm (10.8~13.0 in-lbf).
Follow the torque pattern shown in above image (numbers 1-6).
