Cooling 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. Note, those heatsinks are recommended for maintaining the specified
Maximum T case requirement. In addition, this collection is not intended to be a
comprehensive listing of all heatsinks that support Intel processors.

2-3-2 About Intel Pentium 4 478-pin CPU
This motherboard provides a 478-pin surface mount, Zero Insertion Force (ZIF) socket,
referred to as the mPGA478B socket supports Intel Pentium 4 processor in the 478 Pin
package utilizes Flip-Chip Pin Grid Array (FC-PGA2) package technology.
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.
mPGA478B
Colden Arrow
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.

2-4 Install Memory
This motherboard provides two 184-pin DDR DUAL INLINE MEMORY MODULES
(DIMM) sites for DDR memory expansion available from minimum memory size of 64MB to
maximum memory size of 2.0GB SDR SDRAM, or one 168-pin SDR DIMM sites for
SDRAM memory for maximum memory size of 1.0GB.

Generally, installing SDR/DDR SDRAM modules to your motherboard is very easy, you can
refer to figure 2-4 to see what a 168-pin SDR/184-pin DDR SDRAM module looks like.
DDR2 (BANK2 + BANK3)
DDR1 (BANK0 + BANK1)
SDR1 (BANK0 + BANK1 )
Figure 2-4
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 SDR SDRAM CLOCK is set at 133MHz, use only PC133/DDR266compliant SDR/DDR Modules. 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 SDR/DDR Modules are not PC133/DDR266-compliant, set
the SDRAM clock to 100MHz to ensure system stability.
NOTE!
It is only can install either SDRAM or DDR Module at one time. Don’t install
both DDR Module and SDR Module at same time, it will have risk to damage
your Memory and Motherboard.
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
10
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
IRQ Priority Standard function
0 N/A System Timer
1 N/A Keyboard Controller

(1) Power Connector (20-pin block) : ATXPWR
ATX Power Supply connector. This is a new defined 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
motherboard. When the power switch on the back of the ATX power supply turned on, the
full power will not come into the system board until the front panel switch is momentarily
pressed. Press this switch again will turn off the power to the system board.
