Warning: INTEL i815E 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 JP14 to
clear CMOS and restore to the default setting.
Installing CPU and Fan
Plug CPU to Socket370. Be careful of CPU
orientation. Plug in the fan cable to the 3-pin
CPUFAN
or
FAN
1 connector.
Note: Some CPU fans do not
have sensor pin, so that cannot
support fan monitoring.

Auto-Dectect CPU Core Voltage
This motherboard supports Celeron / Pentium III CPU VID function. The CPU
core voltage will be automatically detected and the range is from 1.3V to 3.5V.
Setting CPU Frequency
The CPU frequency selection is set by going into:
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup

JP23/JP29 FSB/PCI Clock Ratio
This jumper is used to specify the relationship of PCI and
host 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.
