This chapter provides you with the information about
hardware setup procedures. While doing the installa-
tion, be careful in holding the components and follow the
installation procedures. For some components, if you
install in the wrong orientation, the components will not
work properly.

When you install the mainboard, you have to place the mainboard into the chassis in the
correct direction. The locations of screws holes on the mainboard are shown as below.
Refer above picture to install stando󰘯s in the appropriate locations on chassis and then
screw through the mainboard screw holes into the stando󰘯s.
Important
To prevent damage to the mainboard, any contact between the mainboard circuit and
chassis or unnecessary stando󰘯s mounted on the chassis is prohibited.
Please make sure there is no metal components placed on the mainboard or within
the chassis that may cause short circuit of the mainboard.

CPU (Central Processing Unit)
When you are installing the CPU, make sure to install the cooler to prevent overheating.
If you do not have the CPU cooler, consult your dealer before turning on the computer.

Overheating
Overheating will seriously damage the CPU and system. Always make sure the cooling
fan can work properly to protect the CPU from overheating. Make sure that you apply
an even layer of thermal paste (or thermal tape) between the CPU and the heatsink to
enhance heat dissipation.
Replacing the CPU
While replacing the CPU, always turn o󰘯 the ATX power supply or unplug the power
supply’s power cord from the grounded outlet 󰘰rst to ensure the safety of CPU.
Overclocking
This mainboard is designed to support overclocking. However, please make sure your
components are able to tolerate such abnormal setting, while doing overclocking. Any
attempt to operate beyond product speci󰘰cations is not recommended. We do not guar-
antee the damages or risks caused by inadequate operation or beyond product speci-
󰘰cations.
Introduction to LGA 1156 CPU
