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)
This mainboard supports Intel®processor in LGA 775 package. W hen you are install-
ing 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.
Introduction to LGA 775 CPU

Remember to apply some ther-
mal paste on it for better heat

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.

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.
2. Remove the cap from lever hinge
side (as the arrow shows).
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.
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.
3. The pins of socket reveal. 4. Open the load lever.

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 align-
ment keys are matched.
8. Cover the load plate onto the
package.
7. Visually inspect if the CPU is
seated well into the socket. If not,
take out the CPU with pure vertical
motion and reinstall.

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 con-
firm that the clip-ends are cor-
rectly inserted.
11. Press the four hooks down to fas-
ten the cooler. Then rotate the lock-
ing switch (refer to the correct di-
rectionmarkedonit)tolockthe
hooks.
9. Press down the load lever lightly
onto the load plate, and then se-
cure the lever with the hook under
retention tab.

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 depend-
ing on the model you purchase.
