4. Installing CPU & Housing Fan
Plug in the CPU fan cable to the 3-pin FN2 connector. If you have chassis fan, you can
also plug it on FN1 connector.

Fan2 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
Full-range Auto-Detect CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected and the range is from 1.1V to 1.85V.
Supported CPU Frequency
Core Frequency = CPU Bus Clock * CPU Ratio
EV6 Bus Speed = CPU Bus Clock x 2
PCI Clock = CPU Bus Clock / Clock Ratio
AGP Clock = PCI Clock x 2

Warning: AMD-761 chipset supports maximum 133MHz FSB
and 66MHz AGP clock, higher clock setting may cause serious
system damage.
Tip: If your system hangs or fails to boot because of
overclocking, simply use <Home> key to restore the default
setting (433MHz) or you can wait the AOpen "Watch Dog Timer"
reset the system in five seconds and system will auto-detect
hardware again.
