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.

Chipset (core logic) - two or more integrated circuits which control the interfaces
between the system processor, RAM, I/O devises, and adapter cards.

Processor socket - the socket used to mount the system processor on the motherboard.

Slot (AGP, PCI, ISA, RAM) - the slots used to mount adapter cards and system RAM.

AGP - Accelerated Graphics Port - a high speed interface for video cards; runs at 1X

(66MHz), 2X (133MHz), or 4X (266MHz).

PCI - Peripheral Component Interconnect - a high speed interface for video cards,
sound cards, network interface cards, and modems; runs at 33MHz.

Serial Port - a low speed interface typically used for mouse and external modems.

Parallel Port - a low speed interface typically used for printers.

PS/2 - a low speed interface used for mouse and keyboards.

USB - Universal Serial Bus - a medium speed interface typically used for mouse,

keyboards, scanners, and some digital cameras.

Sound (interface) - the interface between the sound card or integrated sound
connectors and speakers, MIC, game controllers, and MIDI sound devices.

BIOS (Basic Input/Output System) - the program logic used to boot up a computer and
establish the relationship between the various components.

Driver - software, which defines the characteristics of a device for use by another
device or other software.

Processor - the "Central Processing Unit" (CPU); the principal integrated circuit used
for doing the "computing" in "personal computer"

Front Side Bus Frequency

- The working frequency of the motherboard, which is

generated by the clock generator for CPU, DRAM and PCI BUS.

CPU L2 Cache

- The flash memory inside the CPU, normally Pentium III CPU has

256K or above, while Celeron CPU will have 128K.

The way to recognize the specification of CPU from the packing Pentium III 370
pins FC-PGA

2-3-2 Setting CPU Bus Clock & Memory Clock Jumper

Setting the front side bus frequency and SDRAM frequency

The motherboard uses jumper JS1, JS2, JS3 and JS4 for the front side bus frequency
and SDRAM frequency setting as shown from the table below:

CPU/SDRAM (MHz) JS1 JS2 JS3 JS4

AUTO ON ON 1-2 1-2

66/100
100/100 OFF OFF 2-3 1-2
133/100 OFF OFF 1-2 1-2
133/133 OFF OFF 1-2 2-3

(Default)

OFF OFF 2-3 2-3

Example: Using a Pentium III 866 CPU with front side bus frequency of 133MHz and

PC-133 SDRAM module, the setting of JS3 will be 1-2 and JS4 will be 2-3.
This sets both CPU BUS CLOCK and SDRAM CLOCK to be 133MHz.

For experience user looking for over clocking possibility, please refer to sec 2-3-4.

2-3-3 Install CPU

11

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
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.

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 JS1, JS2, JS3, JS4 you can choose over clock running by
BIOS CMOS SETUP UTILITY. When you entered CMOS SETUP UTILITY, choose
“Miscellaneous Control” you will see the screen as below then.
You can choose the situation you want to try.

WARNING!

The Design of this motherboard follows chipset and CPU vender’s design
guideline. Any attempts to push beyond product specification are not
recommended and you are taking your own risk to damage your system or
important data. Before over clocking, you must make sure your
components are able to tolerate such abnormal setting, especially CPU,
memory, hard disks, and VGA cards.

This motherboard provides three 168-pin DUAL INLINE MEMORY MODULES
(DIMM) sites for memory expansion available from minimum memory size of 32MB
to maximum memory size of 512MB SDRAM.

NOTE!

Make sure the total installed memory does not exceeds 512MB, otherwise
the system may hang during startup.

Generally, installing SDRAM modules to your motherboard is very easy, you can refer
to figure 2-4 to see what a 168-Pin PC100 & PC133 SDRAM module looks like.

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.
