SafetyPrecautions
• Follow these safety precautions when installing the motherboard
• Wear a grounding strap attached to a grounded device to avoid dam-
age 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
ChoosingaComputerCase
There are many types of computer cases on the market. The motherboard complies
with the specifications for the Micro ATX system case. First, some features on the
motherboard are implemented by cabling connectors on the motherboard to indica-
tors and switches on the system case. Make sure that your case supports all the
features required. Secondly, 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 a Micro ATX form factor of 244 x 170 mm. Choose a case
that accommodates this form factor.
InstallingtheMotherboard in a Case
Refer to the following illustration and instructions for installing the motherboard in
a case.
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.

CheckingJumperSettings
This section explains how to set jumpers for correct configuration of the motherboard.
SettingJumpers
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 re-
move 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.

InstallingtheMotherboard
InstallingHardware
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 has an LGA775 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.
2. Always remove the AC power by unplugging the power cord from
the power outlet before installing or removing the motherboard or
other hardware components.
Warning:
1. Over-clocking components can adversely affect the reliability of the
system and introduce errors into your system. Over-clocking can per-
manently damage the motherboard by generating excess heat in com-
ponents that are run beyond the rated limits.
Fail-Safe Procedures for Over-clocking
Installing the Processor
This motherboard automatically determines the CPU clock frequency and system
bus frequency for the processor. You may be able to change 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.
When end-users encounter failure after attempting over-clocking, please take the
following steps to recover from it.
1. Shut down the computer.
2. Press and hold the “Page Up Key (PgUp)” of the keyboard, and then boot the PC
up.
3. Two seconds after the PC boots up, release the “Page Up Key (PgUp)”.
4. The BIOS returns to the default setting by itself.

Installing Add-on Cards
The slots on this motherboard are designed to hold expansion cards and connect
them to the system bus. Expansion slots are a means of adding or enhancing the
motherboard’s features and capabilities. With these efficient facilities, you can in-
crease the motherboard’s capabilities by adding hardware that performs tasks that are
not part of the basic system.
Before installing an add-on card, check the documentation for the card
carefully. If the card is not Plug and Play, you may have to manually
configure the card before installation.
This motherboard is equipped with two standard PCI slots. PCI
stands for Peripheral Component Interconnect and is a bus standard
for expansion cards, which for the most part, is a supplement of the
older ISA bus standard. The PCI slot on this board is PCI
v2.3compliant.
