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 X-Shift--- (Shift to Higher Performance)
The CPU voltage can be adjusted up by 15 steps for the precisely over-clocking of extra
demanding computing performance.
OC-CON ---High-polymer Solid Electrolysis Aluminum Capacitors
The working temperature is from 55 degrees Centigrade below zero to 125 degrees
Centigrade, OC-CON capacitors possess superior physical characteristics that can be while
reducing the working temperature between 20 degrees Centigrade each time, intact extension
10 times of effective product operation lives, at not rising degrees Centigrade of working
temperatures each time a relative one, life of product decline 10% only too.

This motherboard provides a 940-pin surface mount, Zero Insertion Force (ZIF) socket,
referred to as the mPGA940 socket supports AMD Athlon64 processor in the 940 Pin package
utilizes Flip-Chip Pin Grid Array 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.
