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.

ONLY FOR SERVICE PERSONEL

Always unplug the power cord before
inserting any add-on card or module.

Hardware Setup

CPU (Central Processing Unit)

The mainboard supports Intel® Yonah (Intel® Core™ Duo/ T2000 Seqence) and
Merom Napa Reflash (Intel® Core™ 2 Duo/ T5000 & T7000 Sequence) in PGA
Package. When you are installing the CPU, make sure the CPU has a heat sink
and a cooling fan attached on the top to prevent overheating. If you do not
have the heat sink and cooling fan, contact your dealer to purchase and install
them before turning on the computer.

Important

1. Overheating will seriously damage the CPU and system. Always
make sure the cooling fan can work properly to protect the CPU
from overheating.

2. Make sure that you apply an even layer of heat sink paste (or
thermal tape) between the CPU and the heatsink to enhance heat
dissipation.

3. 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 for PGA Package

1. Locate the CPU socket on the
mainboard.

2. Place the CPU on top of the socket. Make sure to align the gold arrow on the
CPU with the arrow key on the socket.

3. Push the CPU down until its pins securely fit into the socket.

4. On the front end of the CPU socket is
a locking mechanism designed into
the form of a screw head. Make sure
that you actuate or deactuate this
mechanism with a screwdriver be­fore and after installing the CPU.

2-4

Hardware Setup

5. Flip over the mainboard and locate the position of the CPU socket.

6. Detach the shield of the CPU cooler backplate paste and install the backplate
to the back of the CPU socket with holes aligned.

7. The heatsink paste helps to enhance heat dissipation of the CPU. Before

installing the cooler set (fan & heatsink bundled), make sure that you detach
the shield of the heatsink paste under the cooler set.

8. Locate the four screw holes around the CPU socket where the CPU cooler

backplate was installed. Align the cooler set with the screw holes and mount
it on top of the CPU.

9. Screw to secure the cooler set to the mainboard.

10. Connect the fan power cable to the CPUFAN1 connector on the mainboard.

Memory

These DIMM slots are used for installing memory modules.

240-pin, 1.8V

64x2=128 pin 56x2=112 pin

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.

Power Supply

ATX 20-Pin Power Connector: ATX1

This connector allows you to connect to an power supply. To connect to 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.

2. Power supply of 130 watts (and above) is highly recommended for
system stability.

3. ATX 12V power connection should be greater than 6A.
