Chapter 2: BIOS information 2-15

Refer to the CPU documentation before setting the CPU voltage. Setting a high voltage

may damage the CPU permanently, and setting a low voltage may make the system

unstable.

2.4.8 DRAM Voltage [Auto]

Allows you to set the DRAM voltage. The values range from 1.185V to 2.135V with a 0.005V

interval.

According to Intel CPU specication, DIMMs with voltage requirement over 1.65V may

damage the CPU permanently. We recommend you install the DIMMs with the voltage

requirement below 1.65V.

2.4.9 VCCIO Voltage [Auto]

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

interval.

2.4.10 CPU PLL Voltage [Auto]

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

a 0.1V interval.

2.4.11 PCH Voltage [Auto]

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.

2.4.12 Load-Line Calibration [Auto]

Load-line is dened by Intel VRM specication 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. Conguration options:

[Auto] [Disabled] [Enabled]

The actual performance boost may vary depending on your CPU specication.

2.4.13 CPU Spread Spectrum [Auto]

[Auto] Automatic conguration.

[Disabled] Enhances the BCLK overclocking ability.

[Enabled] Sets to [Enabled] for EMI control.
