CPU Ratio

This setting controls the multiplier that is used to determine the internal clock
speed of the processor relative to the external or motherboard clock speed.

CPU Vcore Regulator

This setting allows you to adjust the CPU core voltage from +0.025V to +0.
100V at 0.025 increment. Please note that it may be dangerous to adjust the
Vcore over 10%.

DRAM Voltage

This setting allows you to set the appropriate DRAM voltage. Setting options:

2.50V, 2.56V, 2.60V, 2.65V
