Hardware Setup 2-1

Chapter 2. Hardware Setup

Before the Installation: Turn off the power supply switch (fully turn off the +5V standby power), or

disconnect the power cord before installing or unplugging any connectors or add-on cards. Failing to do
so may cause the motherboard components or add-on cards to malfunction or damaged.

2-1. Install The Motherboard

Most computer chassis have a base with many mounting holes to allow motherboard to be securely
attached on and at the same time, prevented from short circuits. There are two ways to attach the
motherboard to the chassis base:

1. use with studs

2. or use with spacers

In principle, the best way to attach the board is to
use with studs. Only if you are unable to do this
should you attach the board with spacers. Line up
the holes on the board with the mounting holes on
the chassis. If the holes line up and there are
screw holes, you can attach the board with studs.
If the holes line up and there are only slots, you
can only attach with spacers. Take the tip of the
spacers and insert them into the slots. After doing
this to all the slots, you can slide the board into
position aligned with slots. After the board has been positioned, check to make sure everything is OK
before putting the chassis back on.

ATTENTION: To prevent shorting the PCB circuit, please REMOVE the metal studs or spacers if they
are already fastened on the chassis base and are without mounting-holes on the motherboard to align with.

2-2. Install CPU, Heatsink and Fan Assembly

Please pay attention to the following notices
before installing the CPU and heatsink/fan
assembly.

1. Always use the processor with the
Heatsink and Fan Assembly installed.

2. Do not touch the pins on the processor.

3. If you ever need to reinstall the Heatsink
and fan Assembly, please clean the
heatsink surface and apply new thermal
interface material first.

3. Lower the locking lever to the fully locked
position.

1. Pull out the socket locking lever slightly,

then lift it up.

2. Align the corner with triangle mark of the

processor with the marking on the motherboard,
and then place the processor vertical down into
the socket.

KV-85

4. Apply thermal interface material.

5. Place the heatsink and fan assembly onto

the retention frame. Match the heatsink clip
with the socket mounting lug. Hook the spring
clip to the mounting lug.

Hardware Setup 2-3

6. On the other side, push the retention clip

straight down to lock into the plastic lug on the
retention frame.

7. Turn the cam lever to lock into the retention

frame.

8. Attach the four-pin power plug from the

heatsink and fan assembly to the CPU FAN
connector.

For detailed information on how to install your
heatsink and fan assembly, please refer to the
instruction manual came packed with the
heatsink and fan assembly you bought.

2-3. Install System Memory

This system board provides two 184-pin DDR DIMM slots for DDR400 memory modules with memory
expansion size up to 2GB.

Bank Memory Module Total Memory

Bank 0, 1 (DIMM1) 256MB, 512MB, 1GB 256MB ~ 1GB

Bank 2, 3 (DIMM2) 256MB, 512MB, 1GB 256MB ~ 1GB

Total System Memory 256MB ~ 2GB

NOTE: Usually there is no hardware or BIOS setup require after adding or removing memory modules,

but you will have to clear the CMOS memory first if any memory module related problem occurs.

Power off the computer and unplug the AC power cord before installing or removing memory modules.

1. Locate the DIMM slot on the board.

2. Hold two edges of the DIMM module
carefully, keep away of touching its
connectors.

3. Align the notch key on the module with the
rib on the slot.

4. Firmly press the module into the slots until
the ejector tabs at both sides of the slot
automatically snaps into the mounting notch.
Do not force the DIMM module in with extra
force as the DIMM module only fit in one direction.

5. To remove the DIMM modules, push the two ejector tabs on the slot outward simultaneously, and
then pull out the DIMM module.

ATTENTION: Static electricity can damage the electronic components of the computer or optional
boards. Before starting these procedures, ensure that you are discharged of static electricity by touching a
grounded metal object briefly.

2-4. Connectors, Headers and Switches

Here we will show you all of the connectors, headers and switches, and how to connect them. Please read
the entire section for necessary information before attempting to finish all the hardware installation inside
the computer chassis. A complete enlarged layout diagram is shown in Chapter 1 for all the position of
connectors and headers on the board that you may refer to.

WARNING: Always power off the computer and unplug the AC power cord before adding or removing
any peripheral or component. Failing to so may cause severe damage to your motherboard and/or
peripherals. Plug in the AC power cord only after you have carefully checked everything.

ATX Power Input Connectors

(1).

This motherboard provides two power connectors to connect to an ATX12V power supply.

NOTE: It is recommended to connect to a power supply with 350W, 20A +5VDC capacity at least for
heavily loaded system, and 2A +5VSB capacity at least for supporting wake-up features.

(2). FAN Connectors

These 3-pin connectors each provide power to the cooling fans installed in your system.

The CPU must be kept cool by using a powerful fan with heatsink. The system is capable of monitoring
the speed of the CPU fan.

• CPUFAN1: CPU Fan Power Connector

• CASFAN1: Auxiliary Fan Power Connector

WARNING: These fan connectors are not jumpers. DO NOT place jumper caps on these connectors.

KV-85

Hardware Setup 2-7

(3). CMOS Memory Clearing Header

This header uses a jumper cap to clear the CMOS memory.

• Pin 1-2 shorted (default): Normal operation.

• Pin 2-3 shorted: Clear CMOS memory.

WARNING: Turn the power off first (including the +5V standby power) before clearing the CMOS
memory. Failing to do so may cause your system to work abnormally or malfunction.
