Hardware Setup
CPU (Central Processing Unit)
When you are installing the CPU, make sure that you install the cooler to
prevent the CPU from 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 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.
1. Open the load lever.
2.Lift the load lever up and open the
load plate.
3. The CPU socket has a plastic cap on
it to protect the contack from damage.
Before you install CPU, always cover
it to protect the socket pin. Romove
the cap from the lever hinge side (as
the arrow shows).

4.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.

5.Visually inspect if the CPU is seated
well into the socket. If not, take out
the CPU with pure vertical motion and
reinstall.
7.Press down the load lever lightly onto
the load plate, and then secure the
lever with the hook under retention
tab.
6.Cover the load plate onto the
package.
8.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.
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.

Important
1. Read the CPU status in BIOS.
2. Whenever CPU is not installed, always protect your CPU socket pin with the
plastic cap covered (shown in Figure 1) to avoid damaging.

Installing Memory Modules
1. Locate the DIMM slots on the mainboard. Flip open the retaining clip at each side
of the DIMM slot.
2. Align the notch on the DIMM with the key on the slot. Insert the DIMM vertically into
the DIMM slot. Then push it in until the golden finger on the DIMM is deeply inserted
in the DIMM slot. The retaining clip at each side of the DIMM slot will automatically
close if the DIMM is properly seated.
Important
You can barely see the golden finger if the DIMM is properly inserted in the
DIMM slot.

3. Manually check if the DIMM has been locked in place by the retaining clips at the
sides.
4. Follow the same procedures to install more DIMMs if necessary.

Power Supply
20-Pin System Power Connector: JPWR1, JPWR3
This connector allows you to connect to a power supply. To connect the 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.
1. Make sure that all connectors are connected to the power supply to ensure
stable operation of the mainboard.
2. Power supply of 350 watts (and above) is highly recommended for system
stability.
