Hardware Setup
This chapter provides you with the information about
hardware setup procedures. While performing the installation, be careful in holding the components and following the installation procedures. For some components, if
you install in the wrong orientation, the components will
not work properly.
Use a grounded wrist strap before handling computer
components. Static electricity may damage the components.

Screw Holes
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.

the position for
the I/O shield of
the chassis.
Screw holes
Refer above picture to install standoffs in the appropriate locations on chassis and then
screw through the mainboard screw holes into the standoffs.
Important
• To prevent damage to the mainboard, any contact between the mainboard circuit and
chassis or unnecessary standoffs mounted on the chassis is prohibited.
• Please make sure there are no metal components placed on the mainboard or within
the chassis that may cause short circuit of the mainboard.

Hardware Setup
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.
Important
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 off the ATX power supply or unplug the power
supply’s power cord from the grounded outlet first to ensure the safety of CPU.

CPU & Cooler Installation
When you are installing the CPU, make sure the CPU has a cooler attached on the top
to prevent overheating. Meanwhile, do not forget to apply some thermal paste on CPU
before installing the heat sink/cooler fan for better heat dispersion.
Follow the steps below to install the CPU & cooler correctly. Wrong installation will
cause the damage of your CPU & mainboard.
2. Lift the load lever up to fully open
position.
3. After confirming the CPU direction for
correct mating, put down the CPU in
the socket housing frame. Be sure to
grasp on the edge of the CPU base.
Note that the alignment keys are
matched.
4. Remove the plastic cap. Engage the
load lever while pressing down lightly
onto the load plate.

Important
Visually inspect if the CPU is seated well into the socket. If not, take out the CPU with
pure vertical motion and reinstall.

1. Open the load lever.
Hardware Setup
5. Secure the lever near the hook end
under the retention tab.
6. Make sure the four hooks are in proper
position before you install the cooler.
Align the holes on the mainboard
with the cooler. Push down the cooler
until its four clips get wedged into the
holes of the mainboard.
7. Press the four hooks down to fasten
the cooler. Turn over the mainboard
to confirm that the clip-ends are
correctly inserted.
8. Finally, attach the CPU Fan cable
to the CPU fan connector on the
mainboard.
Important
• Confirm if your CPU cooler is firmly installed before turning on your system.
• Do not touch the CPU socket pins to avoid damaging.
• Whenever CPU is not installed, always protect your CPU socket pin with the plastic
cap covered to avoid damaging.
• Please refer to the documentation in the CPU cooler package for more details about
the CPU cooler installation.
• Read the CPU status in BIOS.

Dual-Channel mode Population Rule
In Dual-Channel mode, the memory modules can transmit and receive data with two
data bus lines simultaneously. Enabling Dual-Channel mode can enhance the system
performance. The following illustrations explain the population rules for Dual-Channel
mode.

Important
• DDR3 memory modules are not interchangeable with DDR2, and the DDR3 standard
is not backwards compatible. You should always install DDR3 memory modules in
the DDR3 DIMM slots.
• In Dual-Channel mode, make sure that you install memory modules of the same type
and density in different channel DIMM slots.
• Due to the chipset resource deployment, the system density will only be detected up
to 15+GB (not full 16GB) when each DIMM is installed with a 8GB memory module.

Hardware Setup
Installing Memory Modules
1. The memory module has only one notch on the center and will only fit in the right
orientation.
2. Insert the memory module vertically into the DIMM slot. Then push it in until the
golden finger on the memory module is deeply inserted in the DIMM slot. The plastic
clip at each side of the DIMM slot will automatically close when the memory module
is properly seated.
3. Manually check if the memory module has been locked in place by the DIMM slot
clips at the sides.

Important
You can barely see the golden finger if the memory module is properly inserted in the
DIMM slot.
