ASUS P2-99 User’s Manual 17
NOTES: Overclocking your processor is not recommended. It may result in a slower
speed. Voltage Regulator Output Selection (VID) is not required for Pentium III/II/
Celeron processors because they send VID signals directly to the onboard power
regulator.
Set the jumpers by the Internal speed of your processor as follows:

WARNING! Frequencies above 100MHz exceed the specifications for the on-
board Intel Chipset and are not guaranteed to be stable.

6. CPU Core:BUS Frequency Multiple (BF0, BF1, BF2, BF3)
This option sets the frequency multiple between the Internal frequency of the
CPU and the CPU’s External frequency. These must be set in conjunction with the
CPU Bus Frequency.
