Thermal Solutions
As processor technology pushes to faster speeds and higher performance, thermal
management becomes increasingly crucial when building computer systems.
Maintaining the proper thermal environment is key to reliable, long-term system
operation. The overall goal in providing the proper thermal environment is keeping
the processor below its specified maximum case temperature. Heatsinks induce
improved processor heat dissipation through increased surface area and concentrated
airflow from attached fans. In addition, interface materials allow effective transfers
of heat from the processor to the heatsink. For optimum heat transfer, Intel
recommends the use of thermal grease and 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 evaluated and recommended by Intel for use with Intel
processors.

Front Side Bus Frequency
The working frequency of the motherboard, which is generated by the clock generator for
CPU, DRAM and PCI BUS.
CPU Internal Frequency
The frequency of CPU, which is also the actual working frequency of CPU.
Bus Frequency Ratio
The ratio of the working frequency, multiply Front Side Bus Frequency with Bus
Frequency Ratio will form the CPU Internal Frequency.
CPU L2 Cache
The flash memory inside the CPU, normally Pentium III CPU has 256K or above,
while Celeron CPU will have 128K.
Recognize of CPU
The way to recognize the specification of CPU from the packing Pentium III 370
pins FC-PGA
On the surface of the CPU as shown on the
right picture, under the word of “PENTIUM
III” the code is:
RB 80526 P2 866 256
RB :
FC–PGA packing
P2 :
P2–133MHz front side bus frequency
PY–100MHz front side bus frequency
866 :
CPU internal frequency, where here is
866MHz
256 :
the size of L2 cache, where here is 256K
Celeron FC–PGA
On the surface of the CPU as shown on the
right picture, under the word of “Celeron”
the code is:

12
566/128/66/1.5V
566 :
CPU internal frequency, where here is 566MHz
128 :
the size of L2 cache, where here is 128K

front side bus frequency, where here is 66MHz
1.5V: the voltage for the CPU
2-3-2 Setting CPU Bus Clock & Memory Clock Jumper
Setting the Front Side Bus frequency and SDRAM frequency
The motherboard uses jumper JP7 for the front side bus frequency and SDRAM

Example: Using a Pentium

III 866 CPU with front side bus frequency of 133MHz and
PC-133 SDRAM module, the setting of JP7 are 1-2 closed, 3-4 closed, 5-6
closed 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 motherboard provides a ZIF socket 370. The CPU that comes with the
motherboard should have a cooling FAN attached to prevent overheating. If this is
not the case, then purchase a correct cooling FAN before you turn on your system.
WARNING! Be sure that there is sufficient air circulation across the processor’s
heatsink and CPU cooling FAN is working correctly, otherwise it
may cause the processor and motherboard overheat and damage,
you may install an auxiliary cooling FAN, if necessary.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF
socket and open it by first pulling the level sideways away from the socket then

13
upward to a 90-degree angle. Insert the CPU with the correct orientation as shown
below. The notched corner should point toward the end 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.
CPU ZIF Socket 370
Colden Arrow

Intel
PentiumIII
When you put the CPU into the ZIF socket. No force require to insert of the CPU,
then press the level to Locate position slightly without any extra force.
2-3-4 Over clock Running
WARNING! This section is for experienced motherboard installer only. Over
clocking can result in system instability or even shortening life of
the processor.
After setting the Jumper JP7 you can choose over clock running by BIOS CMOS
SETUP UTILITY. When you entered 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 133MHz,
the wrong setting will cause system can not starting, when it happen you
have to clear CMOS and adjust correct setting for your CPU. Again we
don’t suggest user running over clock.
2-4 Install Memory
This motherboard provides 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.
Valid Memory Configurations

DIMM2 (BANK2+BANK3) DIMM1 (BANK0+BANK1)
NOTE! When you install DIMM module fully into the DIMM socket the eject
tab should be locked into the DIMM module very firmly and fit into its
indention on both sides.
WARNING! For the SDRAM CLOCK is set at 133MHz, use only PC133-
compliant DIMMs. When this motherboard operate at 133Mhz,
most system will not even boot if non-compliant modules are used
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
WARNING! Turn off your power when adding or removing expansion cards or
other system components. Failure to do so may cause severe
damage to both your motherboard and expansion cards.
2-5-1 Procedure For Expansion Card Installation
1. Read the documentation for your expansion card and make any necessary
hardware or software setting for your expansion card such as jumpers.
2. Remove your computer’s cover and the bracket plate on the slot you intend to
use.
3. Align the card’s connectors and press firmly.
4. Secure the card 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 driver for your expansion card.

2-5-2 Assigning IRQs For Expansion Card
Some expansion cards need an IRQ to operate. Generally, an IRQ must exclusively
assign to one use. In a standard design, there are 16 IRQs available but most of
them are already in use.
Standard Interrupt Assignments
