Chapter 2 Installation

is is a Mini-ITX form factor motherboard. Before you install the motherboard,

study the conguration of your chassis to ensure that the motherboard ts into it.

Pre-installation Precautions

Take note of the following precautions before you install motherboard components

or change any motherboard settings.

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.

In order to avoid damage from static electricity to the motherboard’s components,

•

NEVER place your motherboard directly on a carpet. Also remember to use a grounded

wrist strap or touch a safety grounded object before you handle the components.

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

•

Whenever you uninstall any components, place them on a grounded anti-static pad or

•

in the bag that comes with the components.

When placing screws to secure the motherboard to the chassis, please do not over-

•

tighten the screws! Doing so may damage the motherboard.

2.2 Installing the CPU Fan and Heatsink

Aer 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 dissipation. Ma ke sure that the

CPU and the heatsink are securely fastened and in good contact with each other.

Please turn o the power or remove the power cord before changing a CPU or heatsink.
