SW1 Settings: Clock Multiplier, CPU Voltage, and
CPU Overheating Protection
This section shows the SW1 clock multiplier and voltage settings for Intel, AMD,
Cyrix/IBM, and IDT CPUs. 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.
SW1: Pins 1, 2, & 3 (Clock Multiplier)
Pins 1, 2, & 3: Clock Multiplier for P55C, K6, K6-2, K6-III, 6X86MX, MII
(Dual-Voltage), C6, WinChip2, and P54C (Single-Voltage)
