WARNING! Frequencies other than the recommended CPU bus frequencies are
not guaranteed to be stable. Overclocking your processor is not recommended. It
may result in a slower speed and premature wearing of the processor.
3) CPU External Frequency Setting (SW1 Switches 1–4)
This option tells the clock generator what frequency to send to the CPU, SDRAM,
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. For normal frequencies, 100, 103 and 105 MHz, the JF jumpers must be set
to [1-2]. For the purpose of overclocking, 133 MHz and above, the JF
jumper must be set to [2-3] and speed adjustments must be made through
BIOS using JumperFree Mode and a 133 MHz capacity processor.
2. To use the manual DSW (SW1) switches as shown below, the JEN must be
set to Jumper Mode: [1-2]; (See 1, p. 18).
3. Otherwise, if JumperFree Mode is enabled, all DSW (SW1) switches must
be set to OFF and the JEN jumper must be set to [2-3]. (See #1 on the previ-
ous page). Then, the BIOS setup can be used in place of these switches (Set
Operating Frequency Setting to User Define under 4.4 Advanced Menu in
BIOS Setup to set the CPU Frequency).
4. If processor settings above 133 MHz are required, then you must use a 133
MHz capacity processor, JumperFree Mode and BIOS to make adjustments.
