Installing the Motherboard

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 Micro ATX system case. 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.

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 244 mm. Choose a case
that accommodates this form factor.

9

Installing the Motherboard 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.

Installing the Motherboard

Do not over-tighten the screws as this can stress 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

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 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.

Warning:

1. 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.

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.

This motherboard has an LGA1155 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.

Fail-Safe Procedures for Over-clocking

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.
