Safety Instructions
To reduce the risk of re, electric shock, and injury, always follow basic safety precautions.
Remember to remove power from your computer by disconnecting the AC main source before
removing or installing any equipment from/to the computer chassis.
Hardware Installation

10
Intel G4X-ITX series Motherboard
Preparing the Motherboard
The motherboard shipped in the box does not contain a CPU or memory. You need to purchase
these to complete this installation.
Installing the CPU
Be very careful when handling the CPU. Make sure not to bend or break any pins on the back.
Hold the processor only by the edges and do not touch the bottom of the processor.
The following illustration shows CPU installtaion components
1. Unhook the socket lever by pushing down and
away from the socket.
2. Lift the load plate. There is a protective socket
cover on the load plate to protect the socket
when there is no CPU installed.
3. Remove the protective socket cover from the
load plate.
4. Remove the processor from its protective cover,
making sure you hold it only by the edges.
It is a good idea to save the cover so that
whenever you remove the CPU, you have a
safe place to store it.
5. Align the notches in the processor with the
notches on the socket.
6. Lower the processor straight down into the
socket without tilting or sliding it into the socket.
Note: Make sure the CPU is fully seated and
level in the socket.
7. Close the load plate over the CPU and press
down while you close and engage the socket
lever.

11
Installing the CPU Fan
There are many different fan types that can be used with this motherboard. Follow the instruction
that came with your fan assembly. Be sure that the fan orientation is correct for your chassis type
and your fan assembly.
Installing Memory Modules
Your new motherboard has two 1.8V 240-pin slots for DDR2 (G41ITX-A)/1.5V 240-pin slots
for DDR3 (G41ITX-B) memory modules. These slots support 512 MB/1 GB/2 GB/4 GB DDR2
(G41ITX-A)/1 GB/2 GB/4 GB DDR3 (G41ITX-B) technologies. They also support dual channel
DDR2 (G41ITX-A)/DDR3 (G41ITX-B) memory technology up to 10.7 GB/s. There must be at
least one memory bank populated to ensure normal operation. Refer to the following recommen-
dations to install memory modules.
q One DIMM: Install it into slot 1 or 2. You can install the DIMM into any slot, however, slot 1
is preferred.
q Two DIMMs: Install them into slot 1 and slot 2.
Note that a memory module has a notch, so it can only t in one direction. Refer to the following
procedure to install memory modules into the slots on the motherboard.
1. Unlock a DIMM slot by pressing the module clips outward.
2. Align the memory module to the DIMM slot, and insert the module vertically into the DIMM
slot. The plastic clips at both sides of the DIMM slot automatically lock the DIMM into the
connector.

Intel G4X-ITX series Motherboard
Installing the Motherboard
The sequence of installing the motherboard into the chassis depends on the chassis you are
using and if you are replacing an existing motherboard or working with an empty chassis. Deter-
mine if it would be easier to make all the connections prior to this step or to secure the mother-
board and then make all the connections. It is normally easier to secure the motherboard rst.
Use the following procedure to install the I/O shield and secure the motherboard into the chassis.
Note: Be sure that the CPU fan assembly has enough clearance for the chassis covers
to lock into place and for the expansion cards. Also make sure the CPU Fan assem
-bly is aligned with the vents on the covers.
Installing the I/O Shield
The motherboard kit comes with an I/O shield that is used to block radio frequency transmis-
sions, protects internal components from dust and foreign objects, and promotes correct airow
within the chassis.
Before installing the motherboard, install the I/O shield from the inside of the chassis. Press the
I/O shield into place and make sure it ts securely. If the I/O shield does not t into the chassis,
you would need to obtain the proper size from the chassis supplier.
Securing the Motherboard into the Chassis
Most computer chassis have a base with mounting studs or spacers to allow the motherboard
to be secured to the chassis and help to prevent short circuits. If there are studs that do not
align with a mounting hole on the motherboard, it is recommended that you remove that stud
to prevent the possibility of a short circuit. In most cases, it is recommended to secure the
motherboard with spacers.
1. Carefully place the motherboard onto the studs/spacers located inside the chassis.
2. Align the mounting holes with the studs/spacers.
3. Align the connectors to the I/O shield.
4. Ensure that the fan assembly is aligned with the chassis vents according to the fan assembly
instruction.
5. Secure the motherboard with screws.
