Overclocking

Operating a CPU at a higher frequency than  it's specification allows is called
overclocking. If the CPU frequency is set at a higher frequency than its specification
allows, it may or may not run at that freqency, depending on the quality of your CPU
and the extent to which the frequency has been overset. The mainboard manufacturer
highly discourages overclocking as it may result in data loss, CPU burn-out, system
failure, etc.

Voltage Configuration

There are two major processor types in general use--single and dual voltage processors.
Most single voltage processors such as Pentium, AMD-K6 and  Cyrix 6x86 processors
use a single voltage value of 3.5v for both core and I/O voltage settings.  Most dual
voltage processors such as Pentium processors with MMX technology and Cyrix
6x86L processors use a dual voltage value of 2.8v for core and 3.3v for I/O voltage
settings.  To make the voltage setting for single and dual voltage processors, simply
set 

JP4 

according to the table on the next page.  The voltage range supported by

this mainboard is detailed in Figure 2-5 below.
