7. 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.
P2B-N CPU Core:Bus Frequency Multiple Selection
WARNING! Frequencies above 100MHz exceed the specifications for the on-
board Intel Chipset and are not guaranteed to be stable.
WARNING! PCI frequencies above 33MHz exceed the specifications for PCI
cards and are not guaranteed to be stable.
Set the jumpers by the Internal speed of your processor as follows:
Intel CPU Model Freq.
Pentium II 450MHz
Pentium II 400MHz
Pentium II 350MHz
Pentium II/Celeron 333MHz
Pentium II/Celeron 300MHz
Pentium II/Celeron 266MHz
NOTES: Overclocking your processor is not recommended. It may result in a slower
speed. Voltage Regulator Output Selection (VID) is not needed for the Pentium II
processor because it sends a VID signal directly to the onboard power controller.
