2-3 Hardware Setup
Central Processing Unit: CPU
The mainboard supports AMD® Athlon™, Athlon™ XP and Duron™ processors in the
462 pin package. The mainboard uses a CPU socket called Socket A for easy CPU
installation. When you are installing the CPU, make sure the CPU has a heat sink
and a cooling fan attached on the top to prevent overheating. If you do not
find the heat sink and cooling fan, contact your dealer to purchase and install them
before turning on the computer.

1.Please turn off the power and
unplug the power cord before
installing the CPU.
2.Pull the lever sideways away
from the socket.  Make sure to
raise the lever up to a 90-de-
gree angle.
3. Look for the gold arrow. The gold
arrow should point towards the
lever pivot. The CPU can only fit
in the correct orientation.
4. If the CPU is correctly installed,
the pins should be completely
embedded into the socket and
can not be seen.  Please note
that any violation of the correct...

Please apply some heat sink paste on top of your CPU to dissipate
the heat more effectively. The following instructions will guide you
through the heat sink installation
procedures. Please consult your agent for
the proper CPU cooler set.

CPU Clock Frequency Selection through BIOS
The hardware configuration for CPU clock frequency of the motherboard is set to
100MHz by default.  Therefore, to make a 133MHz CPU run at 133MHz when it is
installed on the board, you have to adjust the CPU clock frequency in the BIOS setup
utility.
To set the clock frequency for the installed CPU, refer to Frequency/Voltage Control
in Chapter 3. BIOS Setup.

Install at least one DIMM module on the slots.  You can install either single- or double-
sided modules in any order to meet your own needs.
Memory modules can be installed in any combination as follows:
Installing DDR Modules
1.The DDR DIMM has only one notch on the center of module.  The module will only
fit in the right orientation.
2.Insert the DIMM memory module vertically into the DIMM slot. Then push it in until

Power Supply
The mainboard supports ATX power supply for the power system.  Before inserting
the power supply connector, always make sure that all components are installed
properly to ensure that no damage will be caused.
ATX 20-Pin Power Connector: CONN1
This connector allows you to connect to an ATX power supply.  To connect to the ATX
