Note:
Since the latest
processor, Northwood,
would detect the clock
ratio automatically, you
may not be able to
adjust the clock ratio in
BIOS manually.
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.
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.

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. The default setting is "table select
mode". You can adjust the FSB from "CPU Host/SDRAM/PCI Clock" for overclocking.

Note:
If you do not match the CPU
socket Pin 1 and CPU cut edge well,
you may damage the CPU.
Note:
Some CPU fans
do not have sensor pin
so they cannot support
fan monitoring.

Warning:
SIS 650GX Chipset
supports maximum
400MHz system bus,
higher clock setting
may cause serious
system damage.
