CPU Pin 1 and cut edge
CPU socket lever
4. Installing CPU & Housing Fan
Plug in the CPU fan cable to the 3-pin CPU FAN connector. If you have chassis fan,
you can also plug it on FAN2 or FAN3 (without H/W monitoring) connector.
GND
+12V
Sensor
Pull up the CPU socket lever and up to
90-degree angle.
Locate Pin 1 in the socket and look for a
(golden) cut edge on the CPU upper interface.
Match Pin 1 and cut edge. Then insert the
CPU into the socket.
Press down the CPU socket lever and finish
CPU installation.
Note: If you do not match the CPU
socket Pin 1 and CPU cut edge well, it
may damage the CPU.

Note: Some CPU fans do not have
sensor pin, so that cannot support
fan monitoring.
5. Setting CPU Voltage & Frequency
Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected and the range is from 1.1V 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.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
Core Frequency = CPU FSB Clock * CPU Ratio
CPU Ratio From 5.5x to 12.5x step 0.5x
CPU FSB (By BIOS table) 100, 102, 105, 108, 110, 113, 115, 117, 120, 122, 124, 133, 136, 138,
140, 142, 144, 147, 152, 154, and 156MHz.

Warning: VIA Apollo KT266 chipset supports 133MHz FSB (with performance
reaches maximum 266MHz EV6 system bus) and 66MHz AGP clock, higher
clock setting may cause serious system damage.
Tip: If your system hangs or fails to boot because of
overclocking, simply use <Home> key to restore the default
setting (433MHz) or you can wait the AOpen "Watch Dog
Timer" reset the system in five seconds and system will
auto-detect hardware again.
