Installation Guide
For systems with an external clock speed of less than 66MHz (50MHz or
60MHz), there may be a slight performance sacrifice for your
new CPU. For example, changing to a K6-166 from a
Pentium-75 will result in a system upgrade speed of 150MHz
(not 166MHz). In this case, you can get improved
performance by adjusting the external clock speed to
66MHz.
JP2 Settings: CPU Voltage and CPU Overheating
Protection
This section shows the CPU core voltage settings for Intel, AMD, Cyrix/IBM,
and IDT CPUs. It also discusses enabling and disabling the

function.
Pins 1-10: CPU Core Voltage
To reduce power consumption, dual-voltage CPUs use two separate supply
voltages: an I/O interface voltage and a lower core voltage for the processor.
