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 specification, 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 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 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. 2.4.13 CPU Spread Spectrum [Auto] [Auto] Automatic configuration. [Disabled] Enhances the BCLK overclocking ability. [Enabled] Sets to [Enabled] for EMI control. 2-16 ASUS P8H61 PRO

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 specification, 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 PLL voltage. The values range from 1.80V to 1.90V with a 0.1V
interval

Load-Line Calibration [Auto]
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.

CPU Spread Spectrum [Auto]
[Auto]
Automatic configuration.
[Disabled]
Enhances the BCLK overclocking ability.
[Enabled]
Sets to [Enabled] for EMI control.
