CPU Spread Spectrum [Auto]

[Auto]

Automatic configuration.

[Disabled]

Enhances the BCLK overclocking ability.

[Enabled]

Sets to [Enabled] for EMI control.

CPU PLL Voltage [Auto]

Allows you to set the CPU and PCH PLL voltage. The values range from 1.20V to 2.20V with

a 0.00625V interval.

PCH Voltage [Auto]

Allows you to set the Platform Controller Hub voltage. The values range from 0.80V to 1.70V

with a 0.01V interval.

The values of the CPU Manual Voltage, CPU Offset Voltage, DRAM Voltage,

VCCSA Voltage, VCCIO Voltage, CPU PLL Voltage, and PCH Voltage items are

labeled in different color, indicating the risk levels of high voltage settings.

The system may need better cooling system to work stably under high voltage settings.
