3.4.15 DRAM Voltage [Auto] Allows you to set the DRAM voltage. The values range from 1.5V to 2.5V* with a 0.0125V interval. According to Intel CPU spec, 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. 3.4.16 CPU PLL Voltage [Auto] Allows you to set the CPU PLL voltage. The values range from 1.8V to 2.1V with a 0.1V interval. 3.4.17 PCH Voltage [Auto] Allows you to set the Platform Controller Hub voltage. The values range from 1.05V to 1.15V with a 0.10V interval. 3.4.18 DRAM DATA REF Voltage on CHA/B [Auto] Allows you to set the DRAM DATA Reference Voltage on Channel A/B. The values range from 0.395x to 0.630x with a 0.005x interval. Different ratio might enhance DRAM overclocking ability. 3.4.19 DRAM CTRL REF Voltage on CHA/B [Auto] Allows you to set the DRAM Control Reference Voltage on Channel A/B. The values range from 0.395x to 0.630x with a 0.005x interval. Different ratio might enhance DRAM overclocking ability. 3.4.20 Load-Line Calibration [Auto] [Auto] [Disabled] [Enabled] Automatic configuration. Follow Intel specifications. Improve CPU VDroop directly. 3.4.21 CPU Spread Spectrum [Auto] [Auto] [Disabled] [Enabled] Automatic configuration. Enhances the BCLK overclocking ability. Sets to [Enabled] for EMI control. 3.4.22 PCIE Spread Spectrum [Auto] [Auto] [Disabled] [Enabled] Automatic configuration. Enhances the PCIE overclocking ability. Sets to [Enabled] for EMI control.
