DRAM Voltage [Auto] Allows you to set the DRAM voltage. The values range from 1.200V to 2.135V with a 0.005V interval. According to Intel CPU specifications, 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. VCCSA Voltage [Auto] Allows you to set the VCCSA voltage. The values range from 0.610V to 1.560V with a 0.005V interval. PCH Voltage [Auto] Allows you to set the Platform Controller Hub voltage. The values range from 1.05V to 1.40V with a 0.05V interval. • The values of the CPU Manual Voltage, CPU Offset Voltage, DRAM Voltage, VCCSA 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. CPU Manual Voltage CPU Offset Voltage DRAM Voltage VCCSA Voltage PCH Voltage White 0.8V-1.04V 0.005V-0.05V 1.2V-1.575V 0.61V-0.97V 1.05V-1.1V Yellow 1.045V-1.09V 0.055V-0.1V 1.58V-1.65V 0.975V-1.015V 1.15V Pink 1.095V-1.14V 0.105V-0.15V 1.655V-1.725V 1.02V-1.06V 1.2V Red 1.145V-1.99V 0.155V-0.635V 1.73V-2.135V 1.065V-1.56V 1.25V-1.40V The values of CPU Manual Voltage and CPU Offset Voltage vary with CPUs. CPU PLL Voltage [Auto] Allows you to set the CPU and PCH PLL voltage. Configuration options: [Auto] [+0.10V] CPU Spread Spectrum [Auto] [Auto] Automatic configuration. [Disabled] Enhances the BCLK overclocking ability. [Enabled] Sets to [Enabled] for EMI control. Chapter 3 ASUS P8Z77-I DELUXE 3-15
