Installing the Motherboard
Installing the Motherboard in a Case
Refer to the following illustration and instructions for installing the motherboard in a case.
Safety Precautions
• Follow these safety precautions when installing the motherboard
• Wear a grounding strap attached to a grounded device to avoid damage from
static electricity
• Discharge static electricity by touching the metal case of a safely grounded
object before working on the motherboard
• Leave components in the static-proof bags they came in
• Hold all circuit boards by the edges. Do not bend circuit boards
Choosing a Computer Case
There are many types of computer cases on the market. The motherboard complies with
the specifications for the ATX system case. First, some features on the motherboard are
implemented by cabling connectors on the motherboard to indicators and switches on the
system case. Make sure that your case supports all the features required. Secondly, this
motherboard supports one or two floppy diskette drives and four enhanced IDE drives.
Make sure that your case has sufficient power and space for all drives that you intend to
install.
Most cases have a choice of I/O templates in the rear panel. Make sure that the I/O
template in the case matches the I/O ports installed on the rear edge of the motherboard.
This motherboard carries an ATX form factor of 305 x 244 mm. Choose a case that
accommodates this form factor.
Most system cases have mounting brackets installed in the case, which correspond the holes
in the motherboard. Place the motherboard over the mounting brackets and secure the
motherboard onto the mounting brackets with screws.
Ensure that your case has an I/O template that supports the I/O ports and expansion slots
on your motherboard.

Installing the Motherboard
Checking Jumper Settings
This section explains how to set jumpers for correct configuration of the motherboard.
Setting Jumpers
Use the motherboard jumpers to set system configuration options. Jumpers with more than
one pin are numbered. When setting the jumpers, ensure that the jumper caps are placed on
the correct pins.
The illustrations show a 2-pin jumper. When
the jumper cap is placed on both pins, the
jumper is SHORT. If you remove the jumper
cap, or place the jumper cap on just one pin,
the jumper is OPEN.
This illustration shows a 3-pin jumper. Pins
1 and 2 are SHORT
SHORT OPEN
Do not over-tighten the screws as this can stress the motherboard.

necting the motherboard components. Refer to the following:
1 Connect the CPU cooling fan cable to CPU_FAN.
2 Connect the case cooling fan connector to SYS_FAN.
3 Connect the power fan connector to PWR_FAN (optional).
4 Connect the case speaker cable to SPK1.
5 Connect the case switches and indicator LEDs to the F_PANEL.

Installing the Motherboard
Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indication that data
is being read from or written to the hard drive. For the LED to function properly, an IDE
drive should be connected to the onboard IDE interface. The LED will also show activity
for devices connected to the SCSI (hard drive activity LED) connector.
Power/Sleep/Message waiting LED
Connecting pins 2 and 4 to a single or dual-color, front panel mounted LED provides power
on/off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires connecting pin 5 and 7 to a momentary-contact
switch that is normally open. When the switch is closed, the board resets and runs POST.
Power Switch
Supporting the power on/off function requires connecting pins 6 and 8 to a momentary-
contact switch that is normally open. The switch should maintain contact for at least 50 ms
to signal the power supply to switch on or off. The time requirement is due to internal de-
bounce circuitry. After receiving a power on/off signal, at least two seconds elapses before
the power supply recognizes another on/off signal.
Front Panel Connector
The front panel connector (F_PANEL) provides a standard set of switch and LED connec-
tors commonly found on ATX or micro-ATX cases. Refer to the table below for informa-
tion:

Installing the Motherboard
Installing Hardware
Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the motherboard or any of the surface-mount
resistors with the clip of the cooling fan. If the clip of the cooling fan
scrapes across the motherboard, you may cause serious damage to the
motherboard or its components.
On most motherboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the clips.
Also, install the cooling fan in a well-lit work area so that you can clearly
see the motherboard and processor socket.
Before installing the Processor
This motherboard automatically determines the CPU clock frequency and system bus
frequency for the processor. You may be able to change these settings by making changes
to jumpers on the motherboard, or changing the settings in the system Setup Utility. We
strongly recommend that you do not over-clock processors or other components to run
faster than their rated speed.
This motherboard has an LGA775 processor socket. When choosing a processor, consider
the performance requirements of the system. Performance is based on the processor design,
the clock speed and system bus frequency of the processor, and the quantity of internal
cache memory and external cache memory.
Warning: Over-clocking components can adversely affect the reliability
of the system and introduce errors into your system. Over-clocking can
permanently damage the motherboard by generating excess heat in
components that are run beyond the rated limits.

Installing the Motherboard
CPU Installation Procedure
The following illustration shows CPU installation components.
B. Unload the cap
· Use thumb & forefinger to hold the
lifting tab of the cap.
· Lift the cap up and remove the cap
completely from the socket.
C. Open the load plate
· Use thumb & forefinger to hold the
hook of the lever, pushing down and pulling
aside unlock it.
· Lift up the lever.
· Use thumb to open the load plate. Be
careful not to touch the contacts.
D. Install the CPU on the socket
· Orientate CPU package to the socket.
Make sure you match triangle marker
to pin 1 location.
E. Close the load plate
· Slightly push down the load plate onto the
tongue side, and hook the lever.
· CPU is locked completely.
F. Apply thermal grease on top of the CPU.
G. Fasten the cooling fan supporting base onto
the CPU socket on the motherboard.
H. Make sure the CPU fan is plugged to the
CPU fan connector. Please refer to the CPU
cooling fan user’s manual for more detail
installation procedure.
To achieve better airflow rates and heat dissipation, we suggest that you
use a high quality fan with 3800 rpm at least. CPU fan and heatsink
installation procedures may vary with the type of CPU fan/heatsink sup-
plied. The form and size of fan/heatsink may also vary.
A. Read and follow the instructions shown on the
sticker on the CPU cap.
Return Material Authorization (RMA) requests will be accepted only if the
motherboard comes with the cap on the LGA775 socket.
