3.HARDWARE SETUP

4)CPU External Frequency Setting (DSW Switches 1–4)

This option tells the clock generator which frequency to send to the CPU, SDRAM, and chipset. This allows the selection of the CPU’s External frequency. (The CPU External Frequency multiplied by the Frequency Multiple equals the CPU’s Internal frequency (the advertised CPU speed).

IMPORTANT:
1. To use this feature, JEN must	be set to Jumper Mode, [1-2].
(See 1, JumperFree™ Mode (JEN)	in 3, HARDWARE SETUP.)

2.In JumperFree mode, all dip switches (DSW-1–DSW-4) must be set to OFF.

3.When JumperFree mode is enabled, use BIOS setup in place of these switches. (Set Operating Frequency Setting to User Define under 4.4 Advanced Menu in BIOS Setup so you can set the CPU Frequency.)

WARNING! Frequencies other than recommended CPU bus frequencies are not guaranteed to be stable. Overclocking your processor is not advised. It may result in a slower speed and premature wearing of the processor.
