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 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 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 DUAL INLINE MEMORY MODULES (DIMM)
sites for memory expansion available from minimum memory size of 64MB to maximum
memory size of 2.0GB DDR SDRAM.
Valid Memory Configurations
Bank 184-Pin DIMM PCS Total Memory
Bank 0, 1 (DDR1) DDR200/DDR266 DDR SDRAM Module X1 64MB∼1.0GB
Bank 2, 3 (DDR2) DDR200/DDR266 DDR SDRAM Module X1 64MB∼1.0GB
Total System Memory (Max. 2.0GB) X2 64MB∼2.0GB
NOTE! Make sure the installed memory are DDR266 SDRAM support 133MHz
memory clock, otherwise the system may hang during startup.
Generally, installing DDR SDRAM modules to your motherboard is very easy, you can refer
to figure 2-4 to see what a 184-Pin DDR200/DDR266 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 DDR 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 SDR Modules are not DDR266-compliant, set
the DDR 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
IRQ Priority Standard function
0 N/A System Timer
1 N/A Keyboard Controller
2 N/A Programmable Interrupt
3 * 8 Communications Port (COM2)
4 * 9 Communications Port (COM1)
5 * 6 Sound Card (sometimes LPT2)
6 * 11 Floppy Disk Controller
7 * 7 Printer Port (LPT1)
8 N/A System CMOS/Real Time Clock
9 * 10 ACPI Mode when enabled
10 * 3 IRQ Holder for PCI Steering
11 * 2 IRQ Holder for PCI Steering
12 * 4 PS/2 Compatible Mouse Port
13 N/A Numeric Data Processor
14 * 5 Primary IDE Channel
15 * 1 Secondary IDE Channel
* These IRQs are usually available for ISA or PCI devices.

arise between the two PCI groups that will make the system unstable or
cards inoperable.
2-6 Connectors, Headers
2-6-1 Connectors
(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.

•Two hard disks can be connected to each connector. The first HDD is referred to as the
“Master” and the second HDD is referred to as the “Slave”.
•For performance issues, we strongly suggest you don’t install a CD-ROM or DVD-ROM
drive on the same IDE channel as a hard disk. Otherwise, the system performance on this
channel may drop.
