This motherboard supports AMD® Athlon 64 Socket 754 CPU. Be careful of CPU
orientation when you plug it into CPU socket.

1. Installing CPU

2. How to Install Retention Module

1. Pull up the CPU socket lever and up
to 90-degree angle.

2. Locate Pin 1 in the socket and look
for a (golden) cut edge on the CPU
upper interface. Match Pin 1 and
cut edge. Then insert the CPU into
the socket.

3. Press down the CPU socket lever
and finish CPU installation.

Socket Pin 1

Golden Cut Edge

Note: If you do not
match the CPU socket Pin 1
and CPU cut edge well, you
may damage the CPU.

3. Installing CPU & System Fans

Plug in the CPU fan cable to the 3-pin CPU FAN connector. If you have chassis fan,
you can also plug it in SYSFAN1 or SYSFAN2 connector.

IDE Connector

This motherboard comes with a 20-pin and 4-pin ATX power connector as shown
below. Make sure you plug in the right direction. We strongly recommend you to
insert the 4-pin connector before connecting the 20-pin connector.

6. Connecting ATX Power Cables

Attach the power LED, speaker, and reset switch connectors to the corresponding
pins. If you enable “Suspend Mode” item in BIOS Setup, the ACPI & Power LED
will keep flashing while the system is in suspend mode.

Locate the power switch cable from your ATX housing. It is 2-pin female
connector from the housing front panel. Plug this connector to the soft-power
switch connector marked SPWR.

8. Power-on and Loading BIOS Setup

After you finish the setting of jumpers and connect correct cables. Power

Del

on and enter the BIOS Setup, press <Del> during POST (Power On Self
Tes t ).

Choose "Load Setup Defaults" for recommended optimal

performance.

Warning: Please avoid of using "Load Turbo Defaults", unless you are sure your

system components (CPU, RAM, HDD, etc.) are good enough for turbo setting.

Setting CPU Voltage & Frequency

etting

This motherboard supports Voltage ID (VID) function to detect CPU voltage
automatically during power-on. However, if users are willing to do overclocking,
we also provide a range from 0.80V to 1.55V in the BIOS. Sometimes increasing
the original core voltage a little bit will lead the CPU overclock more properly.

Setting CPU Frequency

This motherboard is CPU jumper-less design, you can set CPU frequency through
1MHz stepping CPU Overclocking in the BIOS. CPU Core Frequency = CPU FSB
clock x CPU Ratio. However, all CPU now selling in the market belong to "Fixed
Multiplier". That means users can not adjust the CPU Ratio but only change CPU
FSB clock to achieve overclocking.

(Users do the overclocking at their own risk!!)

BIOS Setup > Frequency / Voltage Control > CPU Speed Setup

CPU Ratio From 4x to 25x step 1x

CPU Clock
(Adjustment manually)

Note: With CPU speed changing rapidly, there might be faster CPU on the market by the time you
received this installation guide. This table is kindly for your references only
distributor for more information.

Note: If your system hangs or fails to boot because of overclocking, simply use
<Home> key to restore the default setting or you can wait the AOpen “Watch Dog ABS”
reset the system in five seconds and system will auto-detect hardware again.

Warning: Supposed you have had adjusted CPU ratio on your current CPU, and
you plan to replace a new CPU. Please use <Home> key or Clear CMOS to restore the
default setting when changing a new CPU, because the system will still implement the
previous CPU setting on the new one.

Gigabit LAN onboard

On the strength of Gigabit LAN controller on board, this motherboard provides
10/100/1000 Mbps Ethernet for office and home use. The Ethernet RJ45
connector is located on top of USB connectors. The right hand side LED indicates
link mode, it lights in orange whenever linking to network. The left hand side LED
indicates the transfer mode and it lights in green when data is transferring in
100Mbps (never lights while in 10Mbps), but lights in orange when transferring in
Gigabit’s mode. To enable or disable this function, you may simply adjust it
through BIOS.

JP14 Clear CMOS

You can clear CMOS to restore system default
setting. To clear the CMOS, follow the procedure
below.

1. Turn off the system and unplug the AC power.

2. Remove ATX power cable from connector PWR2.

3. Locate JP14 and short pins 2-3 for a few seconds.

4. Return JP14 to its normal setting by shorting pin
1 & pin 2.

5. Connect ATX power cable back to connector

JP28 Keyboard/Mouse Wakeup Jumper

This motherboard provides keyboard / mouse wake-up function. You can use JP28
to enable or disable this function, which could resume your system from suspend
mode with keyboard or mouse. The factory default setting is “Disable” (1-2), and
you may enable this function by setting the jumper to 2-3.

USB 2.0 Connector

This motherboard provides eight USB 2.0 ports to connect USB devices, such as
mouse, keyboard, modem, printer, etc. There are four ports on the back panel.
You can use proper cables to connect the Front USB connector to USB modules or
front panel of chassis.

provides data transfer rate up to 400Mb/s, and USB 1.0/1.1just has 12Mbps.
Hence, the IEEE 1394 interface can connect with the devices that need high data
transferring performance, such as digital camera, scanner or others IEEE 1394
devices. Please use the proper cable to connect with devices.
