connector. If you have chassis fan, you
can also plug it on
SYSFAN2

5. Setting CPU Voltage & Frequency
CPU Core Voltage Auto Detectable
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected and the range is from 1.1V ~ 2.025V. It is not necessary to set CPU Core Voltage.
Setting CPU Frequency
This motherboard is CPU jumper-less design, you can set CPU frequency through the BIOS
setup, and no jumpers or switches are needed.
BIOS Setup > Frequency / Voltage Control > CPU Bus Frequency
Core Frequency = CPU FSB Clock * CPU Ratio
Note: Some CPU fans do not have
sensor pin so they cannot support fan
monitoring.

Warning: Intel
®
Springdale-G
chipset supports maximum
800MHz (200MHz*4) system bus
and 66MHz AGP clock; higher
clock setting may cause serious
system damage.

4. Connecting Front Panel Cable
Attach the power LED, speaker, and reset switch connectors to
the corresponding pins. If you enable “Suspend Mode” item in
BIOS Setup, the ACPI & Power LED will keep flashing while the
system is in suspend mode.
Locate the power switch cable from your ATX housing. It is
2-pin female connector from the housing front panel. Plug this
connector to the soft-power switch connector marked
SPWR
.

automatically, you may not be able to
adjust the clock ratio in BIOS
manually.
