Installing Processor - AOpen AX34-U Easy Installation Manual

3. Installing Processor

This socket supports FC-PGA/FCPGA2 package CPU, which is the latest CPU package
developed by Intel, we strongly recommend you not to insert former PPGA-package CPU
onto it.

4. Installing CPU & Housing Fan
Plug in the CPU fan cable to the 3-pin CPU FAN connector. If you have housing fan, you
can also plug it on System FAN 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, it 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 and the range is from 1.05V to 1.825V. 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, no jumpers or switches are needed.
