2-16 ASUS P8P67 LE
2.4.7 Offset Mode Sign [+]
[+] To offset the voltage by a positive value.
[–] To offset the voltage by a negative value.
CPU Offset Voltage [Auto]
Allows you to set the Offset voltage. The values range from 0.005V to 0.635V with a 0.005V
interval.
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 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 0.7350V to 1.6850V with a
0.005V interval.
2.4.10 PCH Voltage [Auto]
Allows you to set the Platform Controller Hub voltage. The values range from 0.7350V to
1.6850V with a 0.005V.
• The values of the CPU Offset Voltage, DRAM Voltage, VCCIO 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.
2.4.11 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 adjust the voltage range from 0% to 100% to boost the
system performance. Configuration options: [Auto] [0% Calibration] [25% Calibration] [50%
Calibration] [75% Calibration] [Full Calibration]
The actual performance boost may vary depending on your CPU specification.
2.4.12 CPU Spread Spectrum [Auto]
[Auto] Automatic configuration.
[Disabled] Enhances the BCLK overclocking ability.
[Enabled] Sets to [Enabled] for EMI control.
