4. JP29 DDR Voltage Jumper

This motherboard supports all DDR266/333/400 DDR RAM in the market. And in order to
get higher and more stable performance of memory, we provide JP29 to adjust the voltage
of RAM from 2.55V to 2.70V. However, if you wish to use DDR400 RAM which requires
higher voltage, you may have to adjust the jumper to set a suitable voltage supply from
2.65V to 2.70. Moreover, you can not run all three RAM in slots at the same time when run
in DDR 400.
DDR Voltage JP29
2.55 V 1-2
2.60 V 3-4
2.65 V 5-6
Pin 1
2.70 V 7-8
Warning: Due to the limitation
SiS648FX/SiS963 Chipset itself,
motherboard does not support DDR 266 when
run in FSB 800.Otherwise, serious damage
will happen to your motherboard and RAM.
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 and you don't need to set the voltage by yourself.
Setting CPU Frequency
This motherboard includes 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 Bus Frequency" for overclocking.
