NOTE: If your processor does not have a locked Frequency Multiple, you must
use CPU Core:Bus Freq. Multiple in 4.4 Advanced Menu (BIOS) to set the
Frequency Multiple. If the Frequency Multiple is locked, setting the Frequency
Multiple in BIOS setup will have no effect.

Multiple in BIOS setup will have no effect.
6) CPU External Frequency Setting (DSW1 Switches 1–4)
This option tells the clock generator what frequency to send to the CPU, SDRAM,
PCI, and the 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. In JumperFree mode, all dip switches must be set to OFF.
2. When JumperFree mode is enabled, use BIOS setup in place of these switches
