Installation Procedures
The mainboard has several user-adjustable jumpers on the board that allow you to
configure your system to suit your requirements. This chapter contains information
on the various jumper settings on your mainboard.
To set up your computer, you must complete the following steps:
Step 1 - Set system jumpers
Step 2 - Install memory modules
Step 3 - Install the Central Processing Unit (CPU)
Step 4 - Install expansion cards
Step 5 - Connect ribbon cables, cabinet wires, and power supply
Step 6 - Set up BIOS software
Step 7 - Install supporting software tools
WARNING: Excessive torque may damage the mainboard. When
using an electric screwdriver on the mainboard, make sure that
the torque is set to the allowable range of 5.0 ~ 8.0kg/cm.
Mainboard components contain very delicate Integrated Circuit
(IC) chips. To prevent static electricity from harming any of the
sensitive components, you should follow the following precautions whenever working on the computer:
1. Unplug the computer when working on the inside.
2. Hold components by the edges and try not to touch the IC
||||chips, leads, or circuitry.
3. Wear an anti-static wrist strap which fits around the wrist.
4. Place components on a grounded anti-static pad or on the bag
that came with the component whenever the components are
separated from the system.

1.) Set System Jumpers
Jumpers are used to select the operation modes for your system. Some jumpers on the board have three metal pins with each pin representing a different
function. A 1 is written besides pin 1 on jumpers with three pins. To set a
jumper, a black cap containing metal contacts is placed over the jumper pin(s)
according to the required configuration. A jumper is said to be shorted when
the black cap has been placed on one or two of its pins.
NOTE: Users are not encouraged to change to jumper settings not
listed in this manual. Changing the jumper settings improperly may
adversely affect system performance.
Clear CMOS
The CMOS RAM is powered by the onboard button cell battery.
T o clear the RTC data:
(1) Turn off your computer;
(2) Open the system case and disconnect the AC power cord;
(3) Place the jumper cap onto the pinpair 2-3 for at least 6 seconds
to clear CMOS data;
(4) Place the jumper cap onto the pinpair 1-2 to normal operation;
(5) Close the system case and connect the AC power cord;
(6) Turn on your computer until CMOS checksum error appears;
(7) Press the Delete key as it boots;
(8) Enter the BIOS Setup to re-enter user preferences.

BIOS Write Protect(Optional)
The jumper helps to prevent the boot block table area in the BIOS ROM
from being overwritten by mistake.

2). Install Memory Modules
1. Locate DD R DIMM sockets
on the mainboard.
2. Install DDR DIMM straight
down into the socket 1 using both
hands, then socket 2, and so forth.
3. The clip on both ends of the
socket will close up to hold the
DDR DIMM in pla ce when the DD R
DIMM reaches the socket bottom.

Mainboard User Guide
3). Install the CPU
The mainboard has a built-in Switching Voltage Regulator to support CPU
Vcore autodetection. That is, it has the ability to detect a nd recognize the CPU
voltage, clock, ratio. Users ca n view the report about CPU frequency through
Frequency / Voltage Control on the BIOS Setup Screen.
CAUTION:
1. The heat sink and fan you installed must be approved by AMD.
2. The mainboard must be placed on a solid surface to avoid shak
ing while install the heat sink and fan are installed on the board.
3. The heat sink must make tight contact with the CPU top.
4. Never run the processor without the he at sink properly and firmly
attached. PERMANENT DAMAGE WILL RESULT!
The procedures below shows you how to install your CPU and its fan
a nd heatsink. First of all, locate the CPU socket on the mainboard.
1. Swing the lever upward to 90 degree.
2. Install the CPU, making sure of the pin 1
orientation by aligning the socket corner marking
with the socket corner closest to the lever tip.
Do not insert the CPU by force. Make sure the
processor is fully inserted into the socket on all
sides.
Affix the CPU by pressing the lever downward
and locking it beside the socket.
10
Page 11
3. Place the fa n with heatsink on the CPU top
and press down on the two plastic clips,
hooking them up with the holes on the two
sides of the retention module.
4. Press the white bar on each clip down to
fasten the fan set on the retention module.
Connect ATX Power
The 20-hole power plug (1st figure) is connected to the ATX power 20-pin
pinheaders. The 4-hole 12V power plug (2nd figure) is inserted in the ATX_12V
power connector.
The plug from the power supply can only be inserted in one orientation
because of the different hole sizes. Find the proper orientation and push down
firmly making sure that the pins are aligned.

Mainboard User Guide
4). Install Expansion Cards
This section describes how to connect an expansion card to one of your
system expansion slots. Expa nsion cards are printed circuit boards that, when
connected to the mainboard, increase the capabilities of your system. For
example, expansion cards can provide video and sound capabilities. The
mainboard features one AGP and three PCI bus expa nsion slots.
CAUTION:
1.Make sure to unplug the power supply when adding or remov
ing expansion cards or other system components. Failure to
do so may cause severe damage to both the mainboard and
expansion cards.
2.Always observe static electricity precautions.
3.Please read Handling Precautions at the start of this manual.
1. Select an availa ble expansion slot.
2. Remove the corresponding slot cover from the computer chassis. Un-
screw the mounting screw that secures the slot cover and pull the slot cover
out from the computer chassis. Keep the slot cover mounting screw nearby.
12
Page 13
3. Push the card firmly into the slot.
Push down on one end of the expansion card, then the other. Use this rocking motion until them card is firmly
seated inside the expansion slot. Secure the card with the screw removed
in Step 2.
5). Connect Devices
