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.
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 a Socket AM3 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.
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.
Installing the Motherboard
CPU Installation Procedure
The following illustration shows CPU installation components.
1Install your CPU. Pull up the lever away from
the socket and lift up to 90-degree angle.
2Locate the CPU cut edge (the corner with
the pin hold noticeably missing). Align and
insert the CPU correctly.
3Press the lever down and apply thermal
grease on top of the CPU.
4Put the CPU Fan down on the retention mod-
ule and snap the four retention legs of the
cooling fan into place.
5Flip the levers over to lock the heat sink in
place and connect the CPU cooling Fan power
cable to the CPUFAN connector. This completes the installation.
To achieve better airflow rates and heat dissipation, we suggest that you
use a high quality fan with 4800 rpm at least. CPU fan and heatsink
installation procedures may vary with the type of CPU fan/heatsink supplied. The form and size of fan/heatsink may also vary.
