Asus P8P67-M - DRAM Voltage; VCCIO Voltage; PCH Voltage; Load-Line Calibration

2-16 ASUS P8P67-M
2.4.7 DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.2000V 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.
2.4.8 VCCIO Voltage [Auto]
Allows you to set the VCCIO voltage. The values range from 1.0500V to 1.6850V with a
0.005V interval.
2.4.9 PCH Voltage [Auto]
Allows you to set the Platform Controller Hub voltage. The values range from 1.0500V to
1.6850V with a 0.005V interval.
• 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.
2.4.10 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 adjust the voltage range from 0% to 100% to boost the
system performance. Conguration options: [Auto] [0% Calibration] [25% Calibration] [50%
Calibration] [75% Calibration] [Full Calibration]
The actual performance boost may vary depending on your CPU specication.
2.4.11 CPU Spread Spectrum [Auto]
[Auto] Automatic conguration.
[Disabled] Enhances the BCLK overclocking ability.
[Enabled] Sets to [Enabled] for EMI control.
