Hardware Setup
This chapter provides you with the information about
hardware setup procedures. While doing the installation,
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.
Use a grounded wrist strap before handling computer
components. Static electricity may damage the
components.

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.
Replaceing 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.
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 specifications is
not recommended. We do not guarantee the damages or risks caused
by inadequate operation or beyond product specifications.

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.
1.The CPU socket has a plastic cap on
it to protect the contact from damage.
Before you install the CPU, always
cover it to protect the socket pin.
3.The pins of socket reveal.
2.Remove the cap from lever hinge
side (as the arrow shows).
4.Open the load lever.
Important
1.Confirm if your CPU cooler is firmly installed before turning on your system.
2. Do not touch the CPU socket pins to avoid damaging.
3. The availability of the CPU land side cover depends on your CPU packing.

Hardware Setup
5.Lift the load lever up and open the
load plate.
7.Visually inspect if the CPU is
seated well into the socket. If not,
take out the CPU with pure vertical
motion and reinstall.
6.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.

9.Press down the load lever lightly
onto the load plate, and then secure the lever with the hook under
retention tab.
11.Press the four hooks down to fas-
ten the cooler. Then rotate the locking switch (refer to the correct direction marked on it) to lock the
hooks.

10. Align the holes on the mainboard
with the heatsink. Push down the
cooler until its four clips get
wedged into the holes of the
mainboard.
12.Turn over the mainboard to confirm that the clip-ends are correctly inserted.
Important
1. Read the CPU status in BIOS (Chapter 3).
2. Whenever CPU is not installed, always protect your CPU socket pin with the
plastic cap covered (shown in Figure 1) to avoid damaging.
3. Mainboard photos shown in this section are for demonstration of the CPU/
cooler installation only. The appearance of your mainboard may vary depending on the model you purchase.

Memory
These DIMM slots are used for installing memory modules.
Since DDR3 modules are not interchangeable with DDR2 and the DDR3 standard is not
backward compatible, you should always install DDR3 memory module in DDR3 slot
(DIMM2/3/5/6), and DDR2 memory module in DDR2 slot (DIMM1/4). Wrong installation
may cause damage of mainboard. Meanwhile, you are not able to boot up your
system if you install DDR2 & DDR3 memory modules simultaneously.

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.
Important
You can barely see the golden finger if the memory module is properly inserted
in the DIMM slot.
3. The plastic clip at each side of the DIMM slot will automatically close.

Installing DDR2/DDR3 Turbo Card
The DDR2/DDR3 Turbo Cards are memory switchers which should be installed in
DIMM slots. If your memory is DDR2, you should install the DIMM_DDR3 side of DDR2/
DDR3 Turbo Cards into DIMM2 and DIMM5. If your memory is DDR3, you should install
the DIMM_DDR2 side of DDR2/DDR3 Turbo Cards into DIMM1 and DIMM4.

Compatible DDR2 memory list
Please refer to the following list to find the available DDR2 memory modules.
This connector allows you to connect an ATX 24-pin power supply.
To connect the ATX 24-pin power supply, make sure the plug of the
power supply is inserted in the proper orientation and the pins are
aligned. Then push down the power supply firmly into the connector.
You may use the 20-pin ATX power supply as you like. If you’d like
to use the 20-pin ATX power supply, please plug your power supply along with pin 1 & pin 13 (refer to the image at the right hand).
