1.3 Special Features
Easy Overclocking
•Quickly adjust CPU frequency multiples with BIOS in JumperFree
™
Mode
•Adjustable FSB/MEM/PCI frequency ratio
•Stepless Frequency Selection (SFS) for fine-tuning system bus frequency
from at 1MHz increments
•Alternatively, easy-to-use DIP switches permit manual adjustment of the
processor external/internal frequency settings.
ASUS C.O.P. (CPU Overheating Protection): With AMD
®
Athlon XP
™
installed, the motherboard offers automatic CPU Overheating Protection
to prolong the life of the entire system. If the CPU temperature exceeds
the set criteria, the PC shuts down automatically.
Temperature, Fan and Voltage Monitoring:CPU temperature is monitored
by the ASIC through the CPU’s internal thermal diode to prevent
overheating and damage. The CPU and system fans can be monitored
for RPM and failure. System voltage levels are monitored to ensure
stable voltage to critical motherboard components.
ACPI Ready: AdvancedConfigurationPowerInterface(ACPI) providesmore
Energy Saving Features for operating systems that support OS Direct
Power Management (OSPM).
Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI
master busses to the memory and processor.
Auto Fan Off: Thesystemfanspowersoffautomaticallyeveninsleepmode.
DualFunction Power Button:Pushthepowerbutton forlessthan4 seconds
when the system is operating places the system into sleep or soft-off

2.1 Motherboard installation
TheA7S333 usestheATXform factor, measuring 21.9 cm(8.6 in.) x30.5 cm
(12 in.) - a standard fit for most large chassis.
2.1.1 Placement direction
When installing the motherboard, take care to orient the chassis correctly:
Theedge with externalports goes to the rear part of the chassis. Refer to the
image below. It may be more convenient to install major cables, the CPU
andmodularcomponentsbeforefixingthe motherboardinsidethecaseframe.
2.1.2 Screw holes
Place six (6) screws into the holes indicated by circles to secure the
motherboard to the chassis.
Place this side towards
the rear of the chassis
CAUTION! Do not overtighten the screws! Doing so may damage the
motherboard.
WARNING! Unplug the power cord before installing the motherboard.
Failureto do so may cause you physical injury and damage motherboard
components.
