Chapter 2 Installation

is is an ATX form factor (12” x 9.6”, 30.5 cm x 24.4 cm) motherboard. Before you install the motherboard, study the conguration of your chassis to ensure that the motherboard ts into it.

Place screws into the holes indicated by circles to secure the motherboard to the chassis.

2.2 Pre-installation Precautions

Take note of the following precautions before you install motherboard components or change any motherboard settings.

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

2. To avoid damaging the motherboard’s 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 the compo- nents.

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

4. Whenever you uninstall any component, place it on a grounded anti-static pad or in

the bag that comes with the component.

5. When placing screws into the screw holes to secure the motherboard to the chassis,

please do not over-tighten the screws! Doing so may damage the motherboard. Make sure to unplug the power cord before installing or removing the motherboard. Failure to do so may cause physical injuries to you and damages to motherboard components.Do not over-tighten the screws! Doing so may damage the motherboard.Before you install or remove any component, ensure that the power is switched o or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.C621A WS

2.3 Installing the CPU and Heatsink

1. Before you insert the CPU into the socket, please check if the PnP cap is on the socket,

if the CPU surface is unclean, or if there are any bent pins in the socket. Do not force to insert the CPU into the socket if above situation is found. Otherwise, the CPU will be seriously damaged.

1. Before you installed the heatsink, you need to spray thermal interface material between the CPU

and the heatsink to improve heat dissipation.

2. Illustration in this documentation are examples only. Heatsink or fan cooler type may dier.C621A WS
