is is a in 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. Make 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.

2.3 Installing Memory Modules (SO-DIMM)
is motherboard provides two 260-pin DDR4 (Double Data Rate 4) SO-DIMM
slots.
Be sure to install the memory module into the DDR4_A2 slot as rst priority;
otherwise, the system may not boot up properly or may operate incorrectly.
It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4 slot;
otherwise, this motherboard and SO-DIMM may be damaged.

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