Installing Cpu - AOpen AX3SP-U Easy Installation Manual

3. Installing CPU

1.
CPU Pin 1 and cut edge

CPU socket lever
4. Installing CPU & Housing Fan
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.

Pull up the CPU socket lever and up to
90-degree angle.
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.
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.

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

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.
