Chaper 2 Hardware Setup
ATTENTION !!!
1. Please refer to your processor installation or other
documentation attached to your CPU for detailed installing instruction.
2. Installing a heat sink and cooling fan is necessary
for proper heat dissipation from your CPU. Incorrect
installation may result in overheating and damage
of your CPU.
3. Before changing the setting of CPU Vcore from BIOS
program, user SHOULD make sure of correct specification both of CPU CLOCK and RATIO. Incorrect
setting may cause damage to your CPU.

2-1 CPU Installation
WARNING !!!
• Make sure that +5V DCV and +3.3 DCV capabilities of your power supply
are suitable for the processor.
• Any attempt to operate the AMD Athlon or Duron processor without a
suitable cooling Fan will damage processor and other component.

2-2 Memory Installation
WARNING!!!
• Make sure to unplug your power supply before adding or removing memory
modules or other system components. Failure to do so may cause severe
damage to both your mainboard and expansion cards.
• Be careful when inserting or removing DIMM. Forcing a DIMM in or out
of a socket improperly may damage the memory module or the socket.
Some DIMMs which contain EDO or FTP DRAM are incompliant with
the mainboard. The M/B supports 2.5V true DDR SDRAM DIMMs only.
Installing DIMM
• Make sure you have the correct memory module type for your mainboard.
• Insert the module(s) as shown below, DIMMs have 184-pins and one
notch that will be matched by the onboard DIMM socket. Memory modules
are installed by inserting them straight into the slot until they “click” in the
right place. They only fit in one direction, so do not force them in by a
wrong direction.

Removing DIMM
• Press down the holding clips on both sides of a DIMM socket and the
module will be released from it.

CAUTION!!
The AGP Pro slot comes with a warning label over the 20-pin bay. Do not
remove this label and the safety tab underneath if you use an AGP card
without a retention notch. Without the labels, AGP cards may be placed
into the wrong place, which certainly will damage your card, slot, and
mainboard. Remove the label ONLY if you will be using an AGP Pro card.

2-4 HDD/FDD Installation
• To install HDD (Hard Disk Drive), you may connect the cable’s blue con nector to the mainboard’s primary (IDE1) or secondary (IDE2) connector,
and then connect the gray connector to your slave device and the black
connector to your master device. If you install two hard disks, you must
configure the second drive to Slave mode by setting its jumper accordingly.
Please refer to your hard disk documentation for the jumper settings.

2-5.3 Frequency Ratio Select (By SW1 DIP1-DIP5)
• The AMD Athlon and Duron processors provides four Frequency ID signals
(FID) for the system controller to indicate the SYSTCLK multiplier at which
the processor core operates. Normally, multiplier (or bus ratio) is detected
automatically. Therefore, if the processor does not support the function,
then “Bus Ratio” can not be selected.
• When DIP5 of SW1 is on, LED “SSF1” will be on, and light is on, it means
that Bus Ratio Select Function is enabled. So as long as your CPU
supports Bus Ratio Select function, then Bus Ratio can be selected by
users.

IMPORTANT:
• Do figure out the correct processor type by processor’s OPN (Ordering
Part Numbers). Correct CPU external frequency is key to ensure reliability
of your system.
• Incorrect CPU external frequency or overclocking might cause unstable
performance, so we strongly recommend to leave “SW3” at default setting
or legal operation.

How to tackle with Jumpers:
• Do not remove the jumper when power is on. Always make sure the power
is off before changing any jumper settings. Otherwise, mainboard could
be damaged.
• In the Jumper setting diagram, all jumper pins covered with black marks
stand for closed pins by jumper caps.

2-6.1 JP1/JP2 Memory Module Voltage Select

NOTE: You can clear CMOS by 2-3 pin closed when the system is POWER
OFF. Then, return to 1-2 pin closed position (default). You may damage
the mainboard if clearing the CMOS with POWER ON. Unplugging the
power cord from power supply before clearing CMOS will be a safest bet
for user.

These fan connectors support CPU/System/chassis cooling fan with +12V.
When connecting wire to FAN connectors, users should pay attention
that the red wire is for the positive current and should be connected to
pin +12V, and the black wire is Ground and should be connected to pin
GND. If your mainboard has Hardware Monitor chipset on-board, you
must use a specially designed fan with speed sensor to take advantage
of this function.
For fans with speed sensors, each rotation of the fan blades will send out
2 electric pulses, by which System Hardware Monitor will work out the
fan rotation speed by counting the pulses.
NOTE:
1. Always consult vendor for proper CPU cooling fan.
2. 2“Yellow” fan connectors are used on this series to mark that they
support fan speed sensor function. The other 2 white fan connectors
do not support sensor function.

(1) This connector connects to a LAN card with a Wake On Ring output.
The connector powers up the system when it receives a wake-up packet
or signal through the LAN card.
(2) This feature requires that Ring Power Up Control feature is enabled in
the BIOS setting “Power Management Setup” and that your system
must be on ATX power supply with at least 720mA / +5V standby power.
