!To prevent electrical shock hazard, disconnect the power cable from the electri-
cal outlet before relocating the system.
!When adding or removing devices to or from the system, ensure that the power
cables for the devices are unplugged before the signal cables are connected. If
possible, disconnect all power cables from the existing system before you add a
device.
!Before connecting or removing signal cables from the motherboard, ensure that
all power cables are unplugged.
!Seek professional assistance before using an adapter or extension cord. These
devices could interrupt the grounding circuit.
!Make sure that your power supply is set to the correct voltage for your area. If
you are not sure about the voltage of the electrical outlet you are using, contact
your local power company.

1.1 Before you Proceed
Take note of the following precautions before you install motherboard components or
change any motherboard settings.
Onboard LED
The motherboard comes with a standby power LED that lights up to indicate that the
system is ON, in sleep mode, or in soft-off mode. This is a reminder that you should
shut down the system and unplug the power cable before removing or plugging in
any motherboard component. The illustration below shows the location of the
onboard LED.
Caution! 1. Unplug the power cord from the wall socket before touching any
component.
2. Use a grounded wrist strap or touch a safely grounded object or a
metal object, such as the power supply case, before handling com-
ponents to avoid damaging them with electrostatic discharge.
3. Hold components by the edges to avoid touching the ICs on them.
4. Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
5. Before 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.
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 eight (8) screws into the holes indicated by circles to secure the motherboard
to the chassis.
Warning! Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so may cause physical injury and/or damage
to motherboard components.
Caution! Do not over tighten the screws! Doing so can damage the motherboard.
Place this side toward the rear of the
chassis.

Note! 1. Make sure the AC power is off before you install the CPU.
2. If installing a dual-core CPU, connect the CPU fan cable to the
CPU_FAN1 connector to ensure system stability.
Caution! 1. Your boxed Intel®LGA775 Core™2 Quad / Core™2 Extreme /
Core™2 Duo / Pentium®Extreme / Pentium®D / Pentium®4 CPU
processor 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 lat-
ter.
2. Upon 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.
3. Keep the cap after installing the motherboard. Your place of pur-
chase or local distributor will process Return Merchandise Authori-
zation (RMA) requests only if the motherboard comes with the cap
on the LGA775 socket.
4. The product warranty does not cover damage to the socket con-
tacts resulting from incorrect CPU installation/removal, or misplace-
ment/loss/incorrect removal of the PnP cap.

2. Press the load lever with your thumb (A), then move it outwards (B) until it is
released from the retention tab.
1. Locate the CPU socket on the
motherboard.
Note! Before installing the CPU, make sure that the socket box is facing
towards you.
Caution! To prevent damage to the socket pins, do not remove the PnP (Pick and
Place) cap unless you are installing a CPU.
3. Lift the load lever in the direction
of the arrow to a 135° angle.

4. Lift the load plate with your
thumb and forefinger to a 100°
angle (A), then push the PnP
cap from the load plate window
to remove (B).
5. Position the CPU over the
socket, making sure that the
gold triangle is on the bot-
tom-left corner of the socket,
then fit the CPU notch to the
socket alignment key.
6. Close the load plate (A),
then push the load lever (B)
until it snaps into the reten-
tion tab.
7. If installing a dual-core CPU,
connect the chassis fan
cable to the CHA_FAN1
connector to ensure system
stability.
Caution! The CPU fits only in one correct orientation. DO NOT force the CPU
into the socket or you may bend the connectors on the socket and/or
damage the CPU!

1.4.2 Installing the CPU Heatsink and Fan
The Intel®LGA775 Core™2 Quad/Core™2 Extreme/Core™2 Duo/Pentium®
Extreme/Pentium®D/Pentium®4 CPU processors require a specially designed heat-
sink and fan assembly to ensure optimum thermal condition and performance.
Note! The motherboard supports Intel® LGA775 processors with the Intel®
Enhanced Memory 64 Technology (EM64T), Enhanced Intel Speed-
Step® Technology (EIST), and Hyper-Threading Technology.
Note! After installation, make sure to plug-in the ATX power cable into the
motherboard.
Note! ! Install the motherboard to the chassis before you install the CPU
fan and heatsink assembly.
! When you buy a boxed Intel®processor, the package includes the
CPU fan and heatsink assembly. If you buy a CPU separately,
make sure that you use only Intel®-certified multi-directional heat-
sink and fan.
Caution! If you purchased a separate CPU heatsink and fan assembly, make
sure that you have properly applied thermal interface material to the
CPU heatsink or CPU before you install the heatsink and fan assembly.
1. Place the heatsink on top
of the installed CPU, mak-
ing sure that the four fas-
teners match the holes on
the motherboard.
Note! Orient the heatsink and fan assembly so that the CPU fan cable is as
close as possible to the CPU fan connector.

Note! Make sure each fastener is oriented as shown, with the narrow groove
directed outward.
2. Push down two fasteners at a time
in a diagonal sequence to secure
the heatsink and fan assembly in

3. Connect the CPU fan cable to the connector on the motherboard labeled
CPU_FAN1.
Caution! 1. Do not forget to connect the fan cables to the fan connectors.
Insufficient air flow inside the system may damage the mother-
board components, and hardware monitoring errors can occur if
you fail to plug this connector.
2. These are not jumpers! DO NOT place jumper caps on the fan
connectors.
