Asus P3B-F NOTE:, 2)CPU External Frequency Selection (DSW-Switches 7-10)

3.HARDWARE SETUP

2)CPU External Frequency Selection (DSW-Switches 7-10)

This option tells the clock generator what frequency to send to the CPU, DRAM, and the PCI bus. This allows the selection of the CPU’s External frequency (or BUS Clock). The BUS Clock multiplied by the Frequency Multiple equals the CPU’s Internal fre- quency (the advertised CPU speed).

NOTE: In JumperFree mode, all dip switches (DSW) must be set to OFF.

NOTE: Overclocking your processor is not recommended. It may result in a slower speed. Voltage Regulator Output Selection (VID) is not needed for the Pentium III /

II/ Celeron processor because it sends VID signals directly to the onboard power controller.

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