G31M-VS  is a Micro ATX form factor (8.8 x 6.7, 22.4 x 17.0 cm) motherboard. Before
you install the motherboard, study the configuration of your chassis to ensure that the
motherboard fits into it.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so may cause physical injuries to you and
damages to motherboard components.

2.2  Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any component.
2. To avoid damaging the motherboard components due to static electricity, NEVER
place your motherboard directly on the carpet or the like. Also remember to use
a grounded wrist strap or touch a safety grounded object before you handle
components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that comes with the component.
      Before you install or remove any component, ensure that the power \
is
      switched off or the power cord is detached from the power supply.
      Failure to do so may cause severe damage to the motherboard, peripherals,
      and/or components.

For the installation of Intel 775-LAND CPU,
please follow the steps below.
Before you insert the 775-LAND CPU into the socket, please check if
the CPU surface is unclean or if there is any bent pin on the socket.
Do not force to insert the CPU into the socket if above situation is
found. Otherwise, the CPU will be seriously damaged.
Step 1. Open the socket:
Step 1-1. Disengaging the lever by depressing down and out on the hook to clear
retention tab.
Step 1-2. Rotate the load lever to fully open po-
sition at approximately 135 degrees.
Step 1-3. Rotate the load plate to fully open po-
sition at approximately 100 degrees.
Step 2. Insert the 775-LAND CPU:
Step 2-1. Hold the CPU by the edges where are
marked with black lines.
Step 2-2. Orient the CPU with IHS (Integrated
Heat Sink) up. Locate Pin1 and the two
orientation key notches.

For proper inserting, please ensure to match the two orientation key
notches of the CPU with the two alignment keys of the socket.
Step 2-3. Carefully place the CPU into the socket
by using a purely vertical motion.
Step 2-4. V erify that the CPU is within the socket
and properly mated to the orient keys.
Step 3. Re move PnP Cap (Pick and Place Cap):
Use your left hand index finger and thumb to
support the load plate edge, engage PnP cap
with right hand thumb and peel the cap from the
socket while pressing on center of PnP cap to
assist in removal.
1. It is recommended to use the cap tab to handle and avoid kicking
    off the PnP cap.
2. This cap must be placed if returning the motherboard for after
    service.
Step 4. Close the socket: Step 4-1. Rotate the load plate onto the IHS.
Step 4-2. While pressing down lightly on load
plate, engage the load lever.
Step 4-3. Secure load lever with load plate tab under retention tab of load lever.

Installation of CPU Fan and Heatsink
This motherboard is equipped with 775-Pin socket that supports Intel 775\
-LAND CPU.
Please adopt the type of heatsink and cooling fan compliant with Intel 775-LAND CPU
to dissipate heat. Before you installed the heatsink, you need to spray \
thermal
interface material between the CPU and the heatsink to improve heat dissipation.
Ensure that the CPU and the heatsink are securely fastened and in good contact with
each other. Then connect the CPU fan to the CPU_FAN connector (CPU_FAN1, see
page 10, No. 3).
For proper installation, please kindly refer to the instruction manuals of
your CPU fan and heatsink.
Below is an example to illustrate the installation of the heatsink for 775-LAND CPU.
Step 1. Apply thermal interfa ce material onto center
of IHS on the socket surface.
Step 2. Place the heatsink onto the socket. Ensure fan cables are oriented on side closest to the
CPU fan connector on the motherboard
(CPU_FAN1, see page 10, No. 3).
Step 3. Align fasteners with the motherboard
throughholes.
Step 4. Rotate the fastener clockwise, then press
down on fastener caps with thumb to install
and lock. Repeat with remaining fasteners.
If you press down the fasteners without rotating them clockwise,
the heatsink cannot be secured on the motherboard.
Step 5.Connect fan header with the CPU fan
connector on the motherboard.
Step 6. Se cure excess cable with tie-wrap to ensure
cable does not interfere with fan operation or
contact other components.

G31M-VS  motherboard provides two 240-pin DDR2 (Double Data Rate 2) DIMM slots,
and supports Dual Channel Memory Technology. For dual channel configuration, you
always need to install two  identical (the same brand, speed, size and chip-type)
memory modules in the DDR2 DIMM slots to activate Dual Channel Memory
Technology. Otherwise, it will operate at single channel mode.
1. It is not allowed to install a DDR memory module into DDR2 slot; otherwise, this motherboard and DIMM may be damaged.
2. If you install only one memory module or two non-identical memory modules, it is unable to activate the Dual Channel Memory Technology.

Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align a DIMM on the slot such that the notch on the  DIMM matches the break
on the slot.
The DIMM only fits in one correct orientation. It will cause permanent
damage to the motherboard and the DIMM if you force the DIMM into the
slot at incorrect orientation.
Step 3. Firmly insert the DIMM into the slot until the retaining clips at both ends fully snap back in place and the DIMM is properly seated.

The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is “Short”. If no jumper cap
is placed on pins, the jumper is “Open”. The
illustration shows a 3-pin jumper whose pin1
and pin2 are “Short” when jumper cap is
placed on these 2 pins.
Jumper Setting Description
PS2_USB_PWR1 Short pin2, pin3 to enable
(see p.10  No. 1)+5VSB (standby) for PS/2
or USB wake up events.
Note: To  select +5VSB, it requires 2 Amp and higher standby current provided by
power supply.
Clear CMOS
(CLRCMOS1, 2-pin jumper)
(see p.10  No. 15)
Note: CLRCMOS1 allows you to clear the data in CMOS. The data in CMOS includes\
 system setup information such as system password, date, time, and system
setup parameters. To clear and reset the system parameters to default setup,
please turn off the computer and unplug the power cord from the power
supply. After waiting for 15 seconds, use a jumper cap to short 2 pins on
CLRCMOS1 for 5 seconds.
