3. HARDWARE SETUP
5) CPU External Frequency Setting (DSW 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. To use this feature, JEN [see 1) JumperFree™ Mode (JEN) in 3. HARD-
WARE SETUP] must be set to Jumper mode or [1-2].
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).

NOTE: The motherboard supports PC100 / PC133 DIMMs or VC SDRAMs
for system memory. Registered DIMMs are not supported [see 3.5 System
Memory (DIMM)].
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.
