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.

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.
2-5Expansion 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.

2-5-4 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).
The AGP Slot also supports AGP Digital Display Card for digital display and TV-out.
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)
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 Diamond 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.
