Voltage Jumper Settings ( VID0, VID1, VID2, VID3, VID4)
Setting the CPU voltage is not necessary for current socket 370
processors. However if required, set the jumpers by referring to the
voltage requirement printed on the surface, or the documentation of
your socket 370 processor. If no voltage is indicated or you are not
sure, default setting “AUTO” is suggested, as shown below.

Sometimes you need to set a little extra voltage to get your CPU running
overclocked or on dual-CeleronTM processor system, for example,
sets the CPU voltage as 2.10V for 2.00V CPU. However, we do not
guarantee the system will function properly under these conditions.
Warning : The socket 370 processor may be damaged if its
required voltage is exceeded. Be sure to properly set the jumpers
by referring to the table above and the voltage requirement.
Dual-Celeron™ Processor System
The Twin Magic CPU card enables the Intel® Celeron™ processor’ s
capability of running on dual-processor system. Since no jumper
setting is needed, the implementation of this attractive feature is best
and easy.
Overclocking Jumper Setting ( JFSB )
JFSB provides users with an option to select 66/100MHz front side
bus. Refer to the table below for information on how to set it.
JFSB CPU FSB
Close AUTO (default)
Open 100MHz FSB
If setting CPU FSB as AUTO, the system detects the front side bus
automatically. If setting CPU FSB as 100MHz, the system will run at
100MHz front side bus no matter what type of processor is used.
However, whether or not your system can be overclocked depends
on your processor’ s capability. We do not guarantee the overclocking
system to be stable.
Please keep Jumper(JFSB) setting in accordance with the
Jumper(JFSB1) on mainboard, or set Jumper(JFSB) default setting
in order to suit Jumper(JFSB1) setting on mainboard.
