Production Introduction
1.1 Before you Proceed
Take note of the following precautions before you install motherboard components or
change any motherboard settings.
zUnplug the power cord from the wall socket before touching any
component.
zUse a grounded wrist strap or touch a safely grounded object or a
metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity
zHold components by the edges to avoid touching the ICs on
them.
zWhenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
zBefore you install or remove any component, ensure that the ATX
power supply 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.

1.2 Motherboard Overview
Before you install the motherboard, study the configuration of your chassis to ensure that
the motherboard fits into it. Refer to the chassis documentation before installing the
motherboard.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so can cause you physical injury and
damage motherboard components.
1.2.1 Placement Direction
When installing the motherboard, make sure that you place it into the chassis in the correct
orientation. The edge with external ports goes to the rear part of the chassis as indicated in
the image below.
1.2.2 Screw Holes
Place four (4) screws into the holes indicated by circles to secure the motherboard to the
chassis.
Do not over tighten the screws! Doing so can damage the
motherboard.
Place this side towards the rear of the
chassis

1.4 Central Processing Unit (CPU)
The motherboard comes with a surface mount 478-pin socket designed for the Intel® Core
Duo / Core Solo / Core 2 Duo CPU with 65nm process.
Take one of the marked corner (with gold
triangle) on the CPU. This mark should
match a specific corner on the socket to
ensure correct installation.
zMake sure the AC power is off before you install the CPU.
zIf installing a dual-core CPU, connect the CPU fan cable to the
CPU_FAN connector to ensure system stability.
zYour boxed Intel® socket 478P Core Duo / Core Solo / Core 2
Duo CPU with 65nm process package should come with
installation instructions for the CPU, heatsink, and the retention
mechanism. If the instructions in this section do not match the
CPU documentation, follow the latter.
zUpon purchase of the motherboard, make sure that the PnP cap
is on the socket and the socket contacts are not bent. Contact
your retailer immediately if the PnP cap is missing, or if you see
any damage to the PnP cap/socket contacts/motherboard
components. Your place of purchase or local distributor will
shoulder the cost of repair only if the damage is
shipment/transit-related.
zKeep the cap after installing the motherboard. Your place of
purchase or local distributor will process Return Merchandise
Authorization (RMA) requests only if the motherboard comes with
the cap on the socket.
zThe product warranty does not cover damage to the socket
contacts resulting from incorrect CPU installation/removal, or
misplacement/loss/ incorrect removal of the PnP cap.

1.4.1 Installing the CPU
1. Locate the CPU socket on the
motherboard.
Before installing the CPU,
make sure that the socket
box is facing towards you.
2. The processor socket comes with a
screw to secure the processor, please
unlock the screw first.

i945GM3-DCQI
20
3. Position the CPU above the socket and
the gold triangular mark on the CPU
must align with pin 1 of the CPU socket.
4. Carefully insert the CPU into the socket
until it fits in place ‘Gold mark’.
5. Turn the screw to the lock position.
The CPU fits in only one
correct orientation. DO
NOT force the CPU into
the socket to prevent
bending the connectors
on the socket and
damaging the CPU.
After installation, make sure to plug-in the ATX power cable to the
motherboard.
