Intel Pentium 4 Processor Family
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 90degree 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 mPGAB Socket
Colden Arrow
mPGA478B
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 DDR SDRAM.
Valid Memory Configurations
Bank 184-pin DDR DIMM Total Memory
Bank 0, 1 (DDR1) DDR266/DDR200 DDR DRAM Module X1 64MB∼1.0GB
Bank 2, 3 (DDR2) DDR266/DDR200 DDR DRAM Module X1 64MB∼1.0GB
Total System Memory (Max. 2.0GB) X2 64MB∼2.0GB
10
Generally, installing DDR SDRAM modules to your motherboard is very easy, you can
refer to figure 2-4 to see what a 184-pin DDR SDRAM module looks like.
DDR2 (BANK2+BANK3)
DDR1 (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 SDR SDRAM CLOCK is set at 133MHz, use only DDR266-
compliant 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 DDR Modules are not DDR266compliant, 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
Figure 2-4
11
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

IMPORTANT! If using PCI cards on shared slots, make sure that the drivers support
“Shared IRQ” or that the cards don’t need IRQ assignments. Conflicts
will arise between the two PCI groups that will make the system
unstable or cards inoperable.
