CPU Core Voltage (Vcore)
3.45V (Intel P54C)
3.52V (Cyrix or AMD K5)
2.9V (AMD K6-166/200 or Cyrix M2)
2.8V (MMX P55C)
3.2V (AMD K6-233)
2.5V/2.2V/2.0V (Reserved)
Warning: Please make sure that you have installed CPU fan
properly if Intel PP/MT-233 or AMD K6-200/233 is being
selected to use. It may cause your system unstable if you can
not meet the heat dissipation requirement from above CPU type.
It is recommended to adopt larger fan on these CPU for better
air flow in the system.

Tip: Normally, for single voltage CPU, Vcpuio (CPU I/O Voltage)
is equal to Vcore, but for CPU that needs dual voltage such as
PP/MT (P55C) or Cyrix 6x86L, Vcpuio is different from Vcore
and must be set to Vio (PBSRAM and Chipset Voltage). The
single or dual voltage CPU is automatically detected by
hardware circuit.

Tip: JP11 pin 11-12 is reserved for future CPU, the most
possible value is 2.0V. It is not yet decided when this manual is
printed. Use voltage meter or check your distributor before you
use pin 11-12.
