Take note of the following precautions before you install mother-

board components or change any motherboard settings.

1. Unplug the power cord from the wall socket before touching any

component. Failure to do so may cause severe damage to the

motherboard, peripherals, and/or components.

2. To avoid damaging the motherboard components due to static

electricity, NEVER place your motherboard directly on the carpet

or the like. Also remember to use a grounded wrist strap or touch

a safety grounded object before you handle components.

3. Hold components by the edges and do not touch the ICs.

4. Whenever you uninstall any component, place it on a grounded

antstatic pad or in the bag that comes with the component.

2.1 CPU Installation2.1 CPU Installation

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 its marked corner

matches the base of the socket lever.

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.

Step 5. Install CPU fan and heatsink. For proper installation, please kindly refer to

the instruction manuals of your CPU fan and heatsink vendors.
