Installing Processor; Setting Cpu Frequency - AOpen AX4PER-G Easy Installation Manual

3. Installing Processor

This socket supports FC-PGA2 package CPU, which is the latest CPU package developed
by Intel. Other forms of CPU package are impossible to be fitted in.
CPU Pin 1 and cut edge
4. Installing CPU & System Fan
Plug in the CPU fan cable to the 3-pin CPUFAN1 connector. If you have chassis fan, you
can also plug it on SYSFAN2 or SYSFAN3 connector.

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.
Note: If you do not match the CPU
socket Pin 1 and CPU cut edge well,
you may damage the CPU.

5. Setting CPU Frequency

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.
