2.1  CPU Installation 

Step 1.  Unlock the socket by lifting the lever up to a 90

angle.

Step 2.  Position the CPU directly above the socket such that the CPU corner with  
 

the golden triangle matches the socket corner with a small triangle.

Step 3.  Carefully insert the CPU into the socket until it fits in place.

 

The CPU fits only in one correct orientation. DO NOT force the CPU 
into the socket to avoid bending of the pins.

Step 4.  When the CPU is in place, press it firmly on the socket while you push    
 

down the socket lever to secure the CPU. The lever clicks on the side tab  

 

to indicate that it is locked.

        

 

 

  

2.2  Installation of CPU Fan and Heatsink 

After you install the CPU into this motherboard, it is necessary to install a 
larger heatsink and cooling fan to dissipate heat. You also need to spray 
thermal grease between the CPU and the heatsink to improve heat dis-
sipation. Make sure that the CPU and the heatsink are securely fastened 
and in good contact with each other. Then connect the CPU fan to the 
CPU FAN connector (CPU_FAN1, see Page 12, No. 3). For proper 
installation, please kindly refer to the instruction manuals of the CPU fan 
and  the heatsink.
