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 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 PCS 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

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 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 DDR Modules are not DDR266-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

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)
