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 in
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 1.10V 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.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setting
Core Frequency = CPU FSB Clock * CPU Ratio
3. Installing Processor
Note: If you do not match the CPU
socket Pin 1 and CPU cut edge well,
you may damage the CPU.

Note: Some CPU fans do not have
sensor pin so they cannot support fan
monitoring.

4. Installing CPU & System Fan
FAN3 Connector
This socket supports Micro-FC-PGA2 package CPU, which is the latest CPU package
developed by Intel. Other forms of CPU package are impossible to be fitted in.

Warning: Intel
®
845E chipset
supports maximum 400MHz
(100MHz*4) / 533MHz
(133MHz*4) system bus and
66MHz AGP clock; higher
clock setting may cause
serious system damage.
Note: Since the latest
processor, Northwood,
would detect the clock
ratio automatically, you
may not be able to
adjust the clock ratio in
BIOS manually.
