CPU FAN
connector. If you have chassis fan,
you can also plug it on
FAN2
or
FAN3
connector.

This motherboard provides keyboard / mouse wake-up function. You can use JP28 to
enable or disable this function, which could resume your system from suspend mode with
keyboard or mouse. The factory default setting is “Enable”(1-2), and you may disable this
function by setting the jumper to 2-3.
5. Setting CPU Voltage & Frequency
4. Installing CPU & Housing Fan
3. JP28 Keyboard/Mouse Wakeup Select Jumper
Note: Some CPU fans do not have
sensor pin, so that they cannot
support fan monitoring.

Tip: If your system hangs or
fails to boot because of
overclocking, simply use
<Home> key to restore the
default setting.
Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected and the range is from 1.10V to 1.85V. 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.
Core Frequency = CPU FSB Clock * CPU Ratio
Warning:
Intel
®
850E chipset
supports maximum 400MHz
(100MHz*4) system bus and
66MHz AGP clock, higher
clock setting may cause
serious system damage.
