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

•

components. Failure to do so may cause physical injuries 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.

2.1 Installing the CPU

1. Before you insert the 1151-Pin 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 in sert the CPU into the socket if above situation is found. Otherwise, the CPU
will be seriously damaged.

2. Unplug all power c ables before in stalling the CPU.

2.3 Installing Memory Modules (DIMM)

is motherboard provides two 288-pin DDR4 (Double Data Rate 4) DIMM slots,

and supports Dual Channel Memory Technology.

1. For dual channel cong uration , you always need to in stall identical (the same b rand,
speed , size and chip-type) DDR4 DIMM pairs.

2. It is unable to activate Du al Channel Memory Technology with only one memory module
installed.

3. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4 sl ot;
otherwise , this motherboard and DIM M may be damaged..

e DIMM only ts in one correct orientation. It will cause permanent dam age to the
motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation.
