Some special features---CPU Thermal Throttling/ CPU Vcore 7-shift / CPU Smart Fan) in this
motherboard are designed for power user to use the over-clocking function in more flexible ways. But
please be caution that the over-clocking maybe causes the fails in system reliabilities. This
motherboard provides the guaranteed performance and meets the demands of the next generation
computing. But if you insist to gain more system performance with variety possibilities of the
components you choose, please be careful and make sure to read the detailed descriptions of these
value added product features, please get them in the coming section.

1-1.1 Special Features of Motherboard

CPU Thermal Throttling Technology---(The CPU Overheat Protection

Technology)
To prevent the increasing heat from damage of CPU or accidental shutdown while at high
workload, the CPU Thermal Throttling Technology will force CPU to enter partially idle
mode from 87.5% to 12.5% according to preset CPU operating temperature in BIOS (from 40
 to 90). When the system senses the CPU operating temperature reaching the preset

value, the CPU operating bandwidth will be decreased to the preset idle percentage to cool
down the processor. When at throttling mode the beeper sound can be optionally selected to
indicate it is in working.

CPU Smart Fan---( The Noise Management SystemOnly support 4-pin CPU cooler )

It’s never been a good idea to gain the performance of your system by sacrificing its acoustics.
CPU Smart Fan Noise Management System is the answer to control the noise level needed for
now-a-day’s high performance computing system. The system will automatically increase the
fan speed when CPU operating loading is high, after the CPU is in normal operating condition,
the system will low down the fan speed for the silent operating environment. The system can
provide the much longer life cycle for both CPU and the system fans for game use and
business requirements.

CPU Vcore 7-Shift--- (Shift to Higher Performance)

The CPU voltage can be adjusted up by 7 steps for the precisely over-clocking of extra
demanding computing performance.

referred to as the LGA775 socket supports Intel Pentium 4 processor in the 775 Pin package
utilizes Flip-Chip Land Grid Array (FC-LGA) 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!

To install a CPU, first turn off your system and remove its cover. Locate the LGA775
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.

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.
