JP29/JP23 FSB/PCI Clock Ratio
Plug CPU to Socket 370 connector. Be careful of
CPU orientation. Plug in the fan cable to the 3-pin
CPUFAN
or
FAN
connector.

Note:
Some CPU fans do not have
sensor pin, so that cannot support
fan monitoring.
Warning:
VIA 694x chipset supports maximum 133MHz FSB and
66MHz AGP clock, higher clock setting may cause serious system
damage.
Home
This jumper is used to specify the relationship of PCI and
FSB clock. Generally speaking, we suggest you do not
change the default setting. But for overclocking, changing
these jumper settings becomes necessary. For example,
you must set JP29 to “5-6” and JP23 to “3-4” if you want to
overclock a 66MHz FSB clock CPU to 100MHz or higher.
Tip:
If your system hangs or fails to boot
because of overclocking, simply use
<Home> key to restore the default setting
(233MHz).
