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.

Introduction of I402R/I402 Motherboard
1-1 Feature of motherboard
The I402R/I402 motherboard is design for use Intel Pentium 4 Processor in 478 Pin
Pack age /N ort hw ood Processor with the Intel 845 Chipset delivers a hi gh pe rf orm an ce
and professional desktop platform solution. Which utilize the Socket 478 design and
the memory size expandable to 2.0GB.
This motherboard use the newest Intel 845 Chipset Supports 400MHz System Bus in
data transfer rate and 133MHz DRAM clock frequency support DDR200/DDR266
SDRAM. The I402R/I402 motherboard offers ULTRA ATA 100 to provide speedier
HDD throughout that boosts overall system performance.
The I402R motherboard including IDE RAID chipset and added extra 2 channel
IDE interface supports either ATA100, or RAID0 (striping), RAID1 (mirroring)
function. Use RAID0 function it can increasing data storage performance, use
RAID1 function it can protect data which save in hard disk drive.
These motherboards also has an integrated AC’97 2.1 CODEC on board which is
fully compatible with Sound Blaster Pro
that gives you the best sound quality and
compatibility.
For those wanting even greater graphic perf orman ce, an A GP 4X s lot is i nclud ed on
the board. (For 1.5V AGP card only. No for 3.3V or Universal AGP card).
With USB control as well as capability of expanding to 4 USB function ports, the
I402R/I402 meet future USB demand also this motherboard has built-in hardware
monitor function. This will monitor and protect your computer. The I402
motherboards integrated Recovery Genius in BIOS protected your hard disk from
virus crash hard disk data, and special design in hardware to protect BIOS from
virus crash BIOS data.
In I402R we design in CPU Vcore Voltage, DDR memory 2.5V Voltage, AGP 1.5V
Voltage those can minor adjustable in BIOS setup. This design can let users
approach over clock demand and also can make system more stable. The I402R/
I402 motherboard provides special function in BIOS Setup to setting CPU Host clock
step by step increasing let users to approach over clocking.
I402R/I402 provides high performance & meets future specification demand. It is
really wise choice for your computer.

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
11
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 (Double Data Rate) SDRAM.
Valid Memory Configurations
Bank 184-Pin DIMM Total Memory
Bank 0, 1 (DDR1) DDR200/DDR266 SDRAM Module X1 64MB∼1.0GB
Bank 2, 3 (DDR2) DDR200/DDR266 SDRAM Module X1 64MB∼1.0GB
Total System Memory (Max. 2.0GB) 2 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 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.
Figure 2-4
12
WARNING!
For the DDR SDRAM CLOCK is set at 133MHz, use only DDR266compliant 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 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

IMPORTANT!
If using PCI cards on shared slots, make sure that the drivers support
“Sh ared IRQ” or that the cards don’t need IRQ assi gnme nts. Conf lict s
will arise between the two PCI groups that will make the system
unstable or cards inoperable.
2-5-4 AGP Slot
This motherboard provides an AGP Slot, only support the 1.5V 4X AGP VGA card.
Do not use AGP 2X card (3.3V) in this motherboard. It will burn and damage the
motherboard due to Intel® 845 chipset can not support AGP 2X (3.3V).
IMPORTANT!
Before you plug-in AGP card, please make sure the following notice
is fully understood and practiced. If your AGP card has “AGP 4X
notch (show below) please make sure your AGP card is AGP 4X
(1.5V) not AGP 2X (3.3V)
14
AGP SLOT
Example 1: SiS 305 & ATi Rage 128 Pro AGP card those golden finger is compatible
with 2X/4X mode AGP slot, but only can support 2X (3.3V) only. If you
install these cards in Intel® 845 based motherboard it will burn and damage
the motherboard.
Example 2: We also find Dimanod Vipper V770 golden finger is design for 2X/4X
mode AGP Slot. It can be adjusted the jumper for AGP 2X (3.3V) or
AGP 4X (1.5V). But the factory default setting is 2X (3.3V). If you
install this AGP card in motherboard without change the jumper setting to
4X (1.5V), it will burn the motherboard.
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.
