Installing the Motherboard
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
Choosinga ComputerCase
There are many types of computer cases on the market. The motherboard complies
with the specifications for the FULL ATX system case. Firstly, 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, this motherboard supports one floppy diskette drive and
two 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 a FULL ATX form factor of 305 x 244 mm. Choose a case
that accommodates this form factor.
Installingthe Motherboard inaCase
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
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 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.

InstallingHardware
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.
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.
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.
This motherboard has a socket AM2+/AM2 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:
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.
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.

11
Installing the Motherboard
1 Install your CPU. Pull up the lever away from
the socket and lift up to 90-degree angle.
2 Locate the CPU cut edge (the corner with
the pin hold noticeably missing). Align and
insert the CPU correctly.
3 Press the lever down and apply thermal
grease on top of the CPU.
4 Put the CPU Fan down on the retention mod-
ule and snap the four retention legs of the
cooling fan into place.
5 Flip the levers over to lock the heat sink in
placeand connectthe CPUcooling Fanpower
cable to the CPU fan connector. This com-
pletes the installation.
CPU Installation Procedure
The following illustration shows CPU installation components.
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 sup-
plied. The form and size of fan/heatsink may also vary.
Installing Memory Modules
This motherboard accommodates four memory modules. It can support four 240-pin
DDR2 1066 (AM2+)/800/667/533/400. The total memory capacity is 32 GB*.
DDR2 SDRAM memory module table
You must install at least one module in any of the four slots. Each module can be
installed with 8 GB of memory.
Do not remove any memory module from its antistatic packaging until
you are ready to install it on the motherboard. Handle the modules only
by their edges. Do not touch the components or metal parts. Always
wear a grounding strap when you handle the modules.
The four DDR2 memory sockets (DDR2_1, DDR2_2, DDR2_3, DDR2_4) are di-
vided into two channels and each channel has two memory sockets as following:
ff
ff Channel 0: DDR2_1, DDR2_2
