ASUS p8z68-m pro Manuel D’Utilisation

Chapter 2: BIOS information

2-17

Allows you to set the VCCIO voltage. The values range from 0.735V to 1.685V with a 0.005V 

interval.

Allows you to set the CPU PLL voltage. The values range from 1.80V to 1.90V with a 0.1V 

interval

Allows you to set the Platform Controller Hub voltage. The values range from 0.735V to 

1.685V with a 0.005V interval.

•  The values of the CPU Voltage, DRAM 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.

Load-line is defined by Intel VRM specification and affects CPU voltage. The CPU working 

voltage will decrease proportionally to CPU loading. Higher load-line calibration would get 

higher voltage and better overclocking performance, but increase the CPU and VRM thermal. 

This item allows you to set this function for better system performance. Configuration options: 

[Auto] [Disabled] [Enabled]

The actual performance boost may vary depending on your CPU specification.

[Auto] 

 Automatic configuration.

[Disabled] 

Enhances the BCLK overclocking ability.

[Enabled] 

Sets to [Enabled] for EMI control.
