CPU External Frequency Selection (SW1 & JFSB1)
This option tells the clock generator which frequency to send to the CPU,
SDRAM and AGP clock, and sets the CPU’s
External
frequency.
(The BUS
Clock multiplied by the Frequency Multiple equals the CPU’s
Internal
frequency, or, the advertised CPU speed.)
Both the dip switch and jumper must be set together.
