Hardware Configuration
Motherboard Layout
The following diagrams show the relative positions of the jumpers, connectors, major
components and memory banks on the motherboard.
NOTE 1) Be sure to check the cable orientation in order to match the colored strip to the pin
1 end of the connector.
2) When you start up the system, please wait for 5 seconds after you power on AC.
# If you are using standard ATX power supply (without P4 12V power
connector), you MUST connect a peripheral power plug (the plug
supplying power to HDD / CDROM) into J16. Thus you can use either
ATX 12V power supply or standard ATX power supply for this motherboard
(Noted : NOT all kinds of standard ATX power supply are guaranteed to be
applicable in this motherboard.).

Jumper Settings
This chapter explains how to configure the motherboard’s hardware. Before using your
computer, make sure all jumpers and DRAM modules are set correctly. Refer to this
chapter whenever in doubt.
CPU Speed Selection
In this motherboard, jumperless feature is implemented such that no jumper is required to
be set for different type of CPU installed.
Notice:
1. Be sure to save the CMOS setting when exit the CMOS.
2. The CPU is frequency multiplier locked, no CPU speed change will be seen
even if the frequency multiplier setting in CMOS setup is changed.

Checking the mounting post
of your computer
Please check your computer
chassis if it is carrying any metal
mounting post at this location.
Remove the mounting post or
add insulation to the post before
putting in the motherboard.

Hardware Setup
To Install DIMMs
1. Locate the DIMM sockets.
2. Holding the DIMM by the edges, remove it from its antistatic package.
3. Make sure the clips at either end of the socket are pushed away from the socket.
4. Position the DIMM above the socket. Align the two small notches in the bottom
edge of the DIMM with the keys in the socket.
5. Insert the bottom edge of the DIMM into the socket.
6. When the DIMM is seated, push down on the top edge of the DIMM until the retaining
clips at the ends of the socket snap into place. Make sure the clips are firmly in
place.
Turn system power off before installing and removing any
device, otherwise you’ll cause the system damage.
