Hardware Installation
This section will guide you through the installation of the motherboard. The topics
covered in this section are:
q Preparing the motherboard
v Installing the CPU
v Installing the CPU fan
v Installing the memory
q Installing the motherboard
qConnecting cables and setting switches
Safety Instructions
To reduce the risk of fire, electric shock, and injury, always follow basic safety precations.
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
Preparing the Motherboard
The motherboard shipped in the box does not contain a CPU and 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.
Use the following procedure to install the CPU onto the motherboard.
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 with out 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.

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 DIMMs
Your new motherboard has two 1.8V 240-pin slots for DDR2 memory. These slots
support 256 MB / 512 MB /1GB / 2GB / 4GB DDR2 technologies. There must be at
least one memory bank populated to ensure normal operation. Use the following the
recommendations for installing memory. (See Figure1 for the location of the memory
slots.)
q One DIMM: You can install the DIMM into any slot,however,slot 1 is preferred.
q Two DIMMs: Install into slots 1 and 2,The idea is to run on dual channel mode.
DDRII-2
DDRII-1

11
Hardware Installation
Use the following procedure to install memory DIMMs into the slots on the mother-
board. Note that there is only one gap near the center of the DIMM slot. This slot
matches the slot on the memory DIMM to ensure the component is installed prop-
erly.
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.
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. Determine if it would be easier to make all the connections prior to this
step or to secure the motherboard and then make all the connections. It is normally
easier to secure the motherboard first.
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 assembly 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
transmissions, protects internal components from dust and foreign objects, and
promotes correct airflow 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 fits securely. If the I/O shield does
not fit into the chassis, you would need to obtain the proper size from the chassis
supplier.

Front panel header - FP1
The front panel header on this motherboard is one connector used to connect the
following four cables :
q PWRLED
Attach the front panel power LED cable to these two pins of the connector. The
Power LED indicates the system’s status.
Note: Some chassis do not have all four cables. Be sure to match the name on
the connectors to the corresponding pins.
q PWR SW
Attach the power button cable from the case to these two pins. Pressing the
power button on the front panel turns the system on and off rather than using the
power supply button.
q HDD LED
Attach the hard disk drive indicator LED cable to these two pins. The HDD
indicator LED indicates the activity status of the hard disks.
q RST SW
Attach the Reset switch cable from the front panel of the case to these two pins.
The system restarts when the RESET switch is pressed.

PCI Slots
The one PCI slot support many expansion cards such as a LAN card, USB card, SCSI
card and other cards that comply with PCI specifications. When installing a card into
the PCI slot, be sure that it is fully seated. Secure the card’s metal bracket to the chas-
sis back panel with the screw used to hold the blank cover.
PCI Express x16 Slots
There is one PCI Express x16 slot reserved for graphics or video cards. The band-
width of the x16 slot is up to 4GB/Sec complianting with PCIE 1.1 specification.
When installing a PCI Express x16 card, be sure the retention clip snaps and locks
the card into place. If the card is not seated properly, it could cause a short across the
pins. Secure the card’s metal bracket to the chassis back panel with the screw used
to hold the blank cover.
PCI Express x1 Slots(optional)
There is one PCI Express x1 slot that is designed to accommodate less bandwidth-
intensive cards, such as a modem or LAN card. The x1 slot provides 500 MB/sec
bandwidth.
Expansion Slots
The Intel G31 motherboard contains three expansion slots, one PCI Express X16 slot
,one PCI Express X1 slot (Optional) and one PCI slot. For a full list of PCI Express x16
