Thermal Solutions
As processor technology pushes to faster spee s an higher performance, thermal
management becomes increasingly crucial when buil ing computer systems. Maintaining
the proper thermal environment is key to reliable, long-term system operation. The
overall goal in provi ing the proper thermal environment is keeping the processor
below its specifie maximum case temperature. Heatsinks in uce improve processor
heat issipation through increase surface area an concentrate airflow from attache
fans. In a ition, interface materials allow effective transfers of heat from the
processor to the heatsink. For optimum heat transfer, Intel recommen s the use of
thermal grease an mounting clips to attach the heatsink to the processor.
When selecting a thermal solution for your system, please refer to the website below
for collection of heatsinks evaluate an recommen e by Intel for use with Intel
processors.

Hardware installation
2-1 Hardware installation Steps
7

Before using your computer, you ha better complete the following steps:
1. Check motherboar setting
2. Install CPU
3. Install Memory
4. Install Expansion car s
5. Connect Ribbon cables, Panel wires, an power supply
6. Setup BIOS
7. Install software river & utility
2-2 Checking Motherboard’s Jumper Setting
1. CPU & SDRAM Clock Setting (8-pin): JP1
The motherboar ’s CPU & SDRAM memory clock a juste through jumper JP1.
Table as below:
CPU/SDRAM (MHz) 1-2 3-4 5-6 7-8
66/66 OFF OFF OFF ON
66/100 OFF OFF OFF OFF
100/100 ON OFF OFF OFF
100/133 ON OFF ON OFF
133/100 ON ON OFF OFF
133/133 ON ON ON OFF
2. Keyboard Power On Function Setting (3-pin): JP7
This allows you to isable the keyboar power on function. Set the jumper to
enable or isable if you wish to use your keyboar (by pressing < >) to power on
your computer. This feature requires an ATX power supply that can supply at least
300mA on the +5VSB lea . The efault is set to isable.
8

3. CMOS RAM Clear (3-pin): JP4
A battery must be use to retain the motherboar configuration in CMOS RAM
short 2-3 pins of JP4 to store the CMOS ata.
Note: You can clear CMOS by shorting 1-2 pin, while the system is off Then
return to 2-3 pin position Avoid clearing the CMOS while the system is
on, it will damage the motherboard always unplug the power cord from
the wall socket

2-3-2 Setting CPU Bus Clock & Memory Clock Jumper
Setting the front side bus frequency and SDRAM frequency
The motherboard uses jumper JP1 for the front side bus frequency and SDRAM
frequency setting as shown from the tab e be ow:
CPU/SDRAM (MHz) 1-2 3-4 5-6 7-8
66/66 OFF OFF OFF ON
66/100 OFF OFF OFF OFF
100/100 ON OFF OFF OFF
100/133 ON OFF ON OFF
133/100 ON ON OFF OFF
133/133 ON ON ON OFF
Example: Using a Pentium

III 866 CPU with front side bus frequency of
133MHz and PC-133 SDRAM module, the setting of JP1 are 1-2 closed,
3-4 closed, 5-6 closed, 7-8 open for CPU BUS CLOCK to be 133MHz and
SDRAM CLOCK to be 133MHz
For experience user looking for over clocking, please refer to sec 2-3-4
2-3-3 Install CPU
This motherboar provi es a ZIF socket 370. The CPU that comes with the
motherboar shoul have a cooling FAN attache to prevent overheating. If this is not
the case, then purchase a correct cooling FAN before you turn on your system.
WARN NG! Be sure that there is sufficient air circulation across the processor’s
heatsink an CPU cooling FAN is working correctly, otherwise it
may cause the processor an motherboar overheat an amage,
you may install an auxiliary cooling FAN, if necessary.
To install a CPU, first turn off your system an remove its cover. Locate the ZIF
socket an open it by first pulling the level si eways away from the socket then
upwar to a 90- egree angle. Insert the CPU with the correct orientation as shown
below. The notche corner shoul point towar the en of the level. Because the CPU
has a corner pin for two of the four corners, the CPU will only fit in the orientation as
shown.
11

When you put the CPU into the ZIF socket. No forces require to insert of the CPU,
then press the level to locate position slightly without any extra force.
2-3-4 Over clock Running
WARN NG! This section is for experience motherboar installer only. Over
clocking can result in system instability or even shortening life of the
processor.
After setting the Jumper JP1 you can choose over clock running by BIOS CMOS
SETUP UTILITY. When you entere CMOS SETUP UTILITY, choose “Frequency/
Voltage control” you will see the screen as below then.
1. You can choose the situation you want to try.

NOTE! The BIOS allows you select Bus Frequency from 66MHz to 140MHz, the
wrong setting will cause system can not starting, when it happen you have
to clear CMOS an a just correct setting for your CPU. Again we on’t
suggest user running over clock.
2-4 Install Memory
This motherboar provi es two 168-pin DUAL INLINE MEMORY MODULES
(DIMM) sites for memory expansion available from minimum memory size of 16MB
to maximum memory size of 1GB SDRAM.
Va id Memory Configurations
Bank 168-Pin D MM Total Memory
Bank 0, 1
(DIMM1)
SDRAM 32, 64, 128, 256, 512MB X 1 16MB512MB
Bank 2, 3
(DIMM2)
SDRAM 32, 64, 128, 256, 512MB X 1 16MB512MB
Total System Memory (Max. 1GB) 16MB1GB
Generally, installing SDRAM mo ules to your motherboar is very easy, you can
refer to figure 2-4 to see what a 168-Pin PC100 & PC133 SDRAM mo ule looks like.
13
Figure 2-4

NOTE! When you install DIMM mo ule fully into the DIMM socket the eject tab
shoul be locke into the DIMM mo ule very firmly an fit into its
in ention on both si es.
WARN NG! For the SDRAM CLOCK is set at 133MHz, use only PC133-compliant
DIMMs. When this motherboar operate at 133Mhz, most system
will not even boot if non-compliant mo ules are use because of the
strict timing issues, if your DIMM are not PC133-compliant, set the
SDRAM clock to 100MHz to ensure system stability.
2-5 Expansion Cards
WARN NG! Turn off your power when a ing or removing expansion car s or
other system components. Failure to o so may cause severe
amage to both your motherboar an expansion car s.
2-5-1 Procedure For Expansion Card Installation
1. Rea the ocumentation for your expansion car an make any necessary
har ware or software setting for your expansion car such as jumpers.
2. Remove your computer’s cover an the bracket plate on the slot you inten to use.
3. Align the car ’s connectors an press firmly.
4. Secure the car on the slot with the screen you remove above.
5. Replace the computer system’s cover.
6. Set up the BIOS if necessary.
7. Install the necessary software river for your expansion car .
2-5-2 Assigning IRQs For Expansion Card
Some expansion car s nee an IRQ to operate. Generally, an IRQ must exclusively
assign to one use. In a stan ar esign, there are 16 IRQs available but most of them
are alrea y in use.
Standard Interrupt Assignments

MPORTANT! If using PCI car s on share slots, make sure that the rivers
support “Share IRQ” or that the car s on’t nee IRQ assignments.
Conflicts will arise between the two PCI groups that will make
the system unstable or car s inoperable.
2-6 Connectors, Headers
1. Power Connector: AT Power Connector (12-pin block): AT
This connector connects to a stan ar AT power supply. To connect the lea s from
the power supply, ensure first that the power supply is not plugge . Most power
supplies provi e two plugs (P8 an P9), each containing six wires, two of which
are black. Orient the connectors so that the black wires are locate in the mi le.
Using a slight angle, align the plastic gui e pins on the lea to their receptacles on
the connector. Once aligne , press the lea onto the connector until the lea locks
into place.
15

2. Power Connector: ATX Power Connector (20-pin block): ATX
ATX Power Supply connector. This is a new efine 20-pins connector that
usually comes with ATX case. The ATX Power Supply allows to use soft power
on momentary switch that connect from the front panel switch to 2-pins Power On
jumper pole on the motherboar . When the power switch on the back of the ATX
