1.
Pull up the CPU socket lever and up to
90-degree angle.
2.
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.
3.
Press down the CPU socket lever and finish
CPU installation.
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
connector.

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 1.05V to 1.825V. It is not necessary to set CPU Core
Voltage
Setting CPU Frequency
CPU frequency can be set through the BIOS setup.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setting
Core Frequency = CPU FSB Clock * CPU Ratio

Tip:
If your system hangs or
fails to boot because of
overclocking, simply use
<Home> key to restore the
default setting or you can wait
the AOpen “Watch Dog
Timer” reset the system in
five seconds and system will
auto-detect hardware again.

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

Warning:
Intel

chipset supports maximum
133MHz FSB and 66MHz AGP
clock, higher clock setting may
cause serious system damage.

Warning:
To avoid possible CPU damage caused by overheating, an automatic shutdown
of system had been especially designed on this motherboard. System would be
automatically power off when this motherboard with implementation of THERMTRIP
circuit detected a CPU temperature above 135 degree for 4 seconds.
