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
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 Output Solid Capacitors (High-polymer Solid Electrolysis Aluminum
Capacitors)
CPU Vcore Input and Output of the motherboard adopts OC-CON solid capacitors to
make it possible for motherboard to work from 55 degrees Centigrade below zero to
125 degrees centigrade. OC-CON capacitors possess superior physical
characteristics to prolong product life ten times than corresponding motherboard
without capacitors every time working temperature increases 20 degrees. Life of
product of motherboard with solid capacitors declines only 10% of those without solid
capacitors as well under same conditions.
3D Audio(Optional for MIP41TA-IC series only)
OP with two-stage Butterworth filter and quadruple noninverting amplifier enhances
bass effect under the 100MHz range to perfect audio effect, brings you stunning
shock experience in video game, true-to-life simulated feeling when watching films
and the greatest touch as that in the concert.

Hardware Installation
WARNING! Turn off your power when installing system components. Failure to
do so may cause severe damage to both your motherboard and the
components.
2-1 Install Intel LGA775 Socket CPU
This motherboard provides a 775-pin DIP, LGA775 Land Grid Array socket, 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.
NOTED! 1.Be sure that there is sufficient air circulation across the processor’s
heat sink 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.
2. We suggest to use CPU under 65W power consumption.
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.

Connectors, Headers & Jumpers Setting
3-1 Connectors
(1) Power Connector (24-pinblock): ATXPWR
ATX Power Supply connector: This is a new defined 24-pins connector that
usually comes with ATX case. The ATX Power Supply allows using 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.
** We recommend that you use an ATX 12V Specification 2.0-compliant power
supply unit (PSU) with a minimum of 350W power rating. This type has 24-pin
and 4-pin power plugs.
** If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the
20-pin power plug can provide at least 15A on +12V and the power supply unit
has a minimum power rating of 350W. The system may become unstable or may
not boot up if the power is inadequate.
