Hardware Setup

CPU (Central Processing Unit)

W hen 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.

Introduction to LGA 775 CPU

The surface of LGA 775 CPU.

Remember to apply some ther-

mal paste on it for better heat

dispersion.

Important

Over heating

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.

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.

3. The pins of socket reveal.

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. W rong installation will

cause the damage of your CPU & mainboard.

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.

5. Lift the load lever up and open the

load plate.

7. Visually inspec t 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 unti l its fou r c lip s g et

wedged int o t he holes of t he

mainboard.

12. Turn over the mainboard to con-

firm that the clip-ends are correctly

inserted.

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.

11. Press the four hooks down to fasten

the cooler. Then rotate the locking

switch (refer to the correct direction

marked on it) to lock the hooks.
