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 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 Offset 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] Allows you to set the CPU Load-Line percentage. Configuration options: [Auto] [Disabled] [Enabled] 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 P8H67-M
