USER’S MANUAL

Pentium®4 Processor Motherboard

Rev. 1.1 Second Edition

12ME-8ITX-1102

When you installing AGP card, please make sure the

following notice is fully understood and practiced. If your
AGP card has "AGP 4X notch"(show below), please make
sure your AGP card is AGP 4X (1.5V).

Do not use AGP 2X card (3.3V) in this motherboard. It will

burn and damage the motherboard due to Intel® 850 chipset
can't support AGP 2X(3.3V).

Example 1: Diamond Vipper V770 golden finger is compatible
with 2X/4X mode AGP slot. It can be switched between AGP 2X
(3.3V) or 4X(1.5V) mode by adjusting the jumper. The factory
default for this card is 2X(3.3V). If you install this card in GA-8ITX
series (or any AGP 4X only) motherboards without switching the
jumper to 4X mode (1.5V), it will burn the motherboard.

Example 2: ATi Rage 128 Pro (Power Color) & SiS 305 golden
finger is compatible with 2X/4X mode AGP slot, but it supports
2X(3.3V) only. If you install this card in GA-8ITX series (or any
AGP 4X only) motherboards, it will burn the motherboard.

WARNING!

W ARNING!

Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To
protect them against damage from static electricity, you should follow some precautions whenever you
work on your computer.

1. Unplug your computer when working on the inside.

2. Use a grounded wrist strap before handling computer components. If you do not have
one, touch both of your hands to a safely grounded object or to a metal object, such as
the power supply case.

3. Hold components by the edges and try not touch the IC chips, leads or connectors, or
other components.

4. Place components on a grounded antistatic pad or on the bag that came with the
components whenever the components are separated from the system.

5. Ensure that the A TX power supply is switched off before you plug in or remove the A TX

power connector on the motherboard.

Installing the motherboard to the chassis…

If the motherboard has mounting holes, but they don’t line up with the holes on the base and there are
no slots to attach the spacers, do not become alarmed you can still attach the spacers to the mounting
holes. Just cut the bottom portion of the spacers (the spacer may be a little hard to cut off, so be careful
of your hands). In this way you can still attach the motherboard to the base without worrying about short
circuits. Sometimes you may need to use the plastic springs to isolate the screw from the motherboard
PCB surface, because the circuit wire may be near by the hole. Be careful, don’t let the screw contact
any printed circuit write or parts on the PCB that are near the fixing hole, otherwise it may damage the
board or cause board malfunctioning.

Introduction

 Please set the CPU host frequency in accordance with your processor’s specifications.

We don’t recommend you to set the system bus frequency over the CPU’s specification
because these specific bus frequencies are not the standard specifications for CPU,
chipset and most of the peripherals. Whether your system can run under these specific
bus frequencies properly will depend on your hardware configurations, including CPU,
Chipsets,SDRAM,Cards….etc.

T o set up your computer , you must complete the following setups:

Step 1- Install the Central Processing Unit (CPU)
Step 2- Install memory modules
Step 3- Install expansion cards
Step 4- Connect ribbon cables, cabinet wires, and power supply
Step 5- Setup BIOS software
Step 6- Install supporting software tools

Socket Actuation Lever

1. Pull up the CPU socket level
and up to 90-degree angle.

3. Press down the CPU socket lever and
finish CPU installation.

2. Locate Pin 1 in the socket and look
for a (golden) cut edge on the CPU
upper corner. Then insert the CPU
into the socket.

CPU Heat Sink Installation

Hardware Installation Process

1. Fasten the heatsink supporting-base
onto the CPU socket on the main­board.

2. Make sure the CPU fan is plugged
to the CPU fan connector, than
install complete.

 Please use Intel approved cooling fan.
 We recommend you to apply the thermal tape to provide better heat

conduction between your CPU and heatsink.
(The CPU cooling fan might stick to the CPU due to the hardening of the
thermal paste. During this condition if you try to remove the cooling fan, you
might pull the processor out of the CPU socket alone with the cooling fan, and
might damage the processor. To avoid this from happening, we suggest you to
either use thermal tape instead of thermal paste, or remove the cooling fan with
extreme caution.)

 Make sure the CPU fan power cable is plugged in to the CPU fan connector,

this completes the installation.

 Please refer to CPU heat sink user’s manual for more detail installation

procedure.

GA-8ITX Series Motherboard

Step 2: Install memory modules

The motherboard has 4 Rambus In-line Memory Module (RIMM) sockets. The BIOS will automati­cally detect memory type and size. To install the memory module, just push it vertically into the
RIMM Slot .The RIMM module can only fit in one direction due to the two notches. Please note; Both
RIMM modules inserted on RIMM1 and RIMM2 slots are recommended to have the same size,
frequency. If not, the larger sized module will l be automatically re-sized by BIOS to match the
smaller sized module. The same rule applies to both RIMM3 and RIMM4 slots.
You can insert two RIMMs or four RIMMs into RIMM slots, but C-RIMM (Continuity RIMM)
modules must be inserted into the empty slots.

RIMM

Check RIMM module if it is supported by the
M/B.

Insert the RIMM module into the slot.

Push the ejector tab towards the RIMM.

CRIMM

 When STR/RIMM LED is ON, you do not install / remove RDRAM from socket.

Step 3: Install expansion cards

1. Read the related expansion card’s instruction document before install the expansion card into
the computer.

2. Remove your computer’s chassis cover, necessary screws and slot bracket from the computer.

3. Press the expansion card firmly into expansion slot in motherboard.

4. Be sure the metal contacts on the card are indeed seated in the slot.

5. Replace the screw to secure the slot bracket of the expansion card.

6. Replace your computer’s chassis cover.

7. Power on the computer, if necessary, setup BIOS utility of expansion card from BIOS.

8. Install related driver from the operating system.
