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.

S446/S446R meet future USB demand also this motherboard has built-in hardware
monitor function to monitor and protect your computer. The S446 motherboards also
integrated Recovery Genius in BIOS to protect your hard disk from virus infect hard
disk data, along with special hardware design to protect BIOS from virus crash BIOS
data.
In S446/S446R, we have adding CPU Vcore Voltage minor adjustment and CPU
Host clock step-by-step increment designs in BIOS Setup Utility in order to ensure
system’s stability while user approach over clock demand.

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.

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 three 184-pin DUAL INLINE MEMORY MODULES
(DIMM) sites for DDR memory expansion available from minimum memory size of
64MB to maximum memory size of 3.0GB DDR SDRAM.

NOTE! Due to SiS 645 chip specification limited it only
can support 2 pcs DDR333
module when DDR clock setting in 166MHz.
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.
DIMM2 (BANK2+BANK3)
DIMM1 (BANK0+BANK1)
DIMM3 (BANK4+BANK5)
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 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 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
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

will arise between the two PCI groups that will make the system
unstable or cards inoperable.
