Installing Processor - AOpen AX45H-8X Easy Installation Manual

3. Installing Processor

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.

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 in SYSFAN2 or SYSFAN3 connector.
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 Voltage & Frequency
Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected.
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. You can adjust the FSB from "CPU
Host/SDRAM/PCI Clock" for overclocking.
