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 resis-

tors 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.

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.

Warning:

1. Over-clocking components can adversely affect the reliability of the

system and introduce errors into your system. Over-clocking can perma-

nently 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.

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.
