CPU Voltage CPU PLL Voltage QPI/DRAM Core Voltage IOH Voltage IOH PCIE Voltage ICH Voltage ICH PCIE Voltage DRAM Bus Voltage Blue 0.85000V- 1.22500V 1.80V-1.90V 1.20000V- 1.26875V 1.10V-1.18V 1.50V-1.58V 1.10V-1.20V 1.50V-1.60V 1.50V-1.64V Yellow 1.23125V- 1.29375V 1.92V-2.00V 1.27500V- 1.32500V 1.20V-1.24V 1.60V-1.66V 1.30V-1.40V 1.70V-1.80V Purple 1.30000V- 1.35000V 2.02V-2.10V 1.33125V- 1.40000V 1.26V-1.30V 1.68V-1.74V N/A N/A Red 1.35625V 1.70000V 2.12V-2.50V 1.40625V- 1.70000V 1.32V-1.70V 1.76V-2.76V N/A N/A N/A N/A 1.66V-2.46V 3.4.17 DRAM DATA REF Voltage on CHA/B/C [Auto] Allows you to set the DRAM DATA Reference Voltage on Channel A/B/C. The values range from 0.395x to 0.630x with a 0.005x interval. Different ratio might enhance DRAM overclocking ability. 3.4.18 DRAM CTRL REF Voltage on CHA/B/C [Auto] Allows you to set the DRAM Control Reference Voltage on Channel A/B/C. The values range from 0.395x to 0.630x with a 0.005x interval. Different ratio might enhance DRAM overclocking ability. 3.4.19 Load-Line Calibration [Auto] Allows you to select the CPU Load-Line mode. Set to [Disabled] to follow Intel specifications, or to [Enabled] to improve CPU VDroop directly. Configuration options: [Auto] [Disabled] [Enabled] 3.4.20 CPU Differential Amplitude [Auto] Different AMP might enhance BCLK overclocking ability. Configuration options: [Auto] [700mV] [800mV] [900mV] [1000mV] 3.4.21 CPU Clock Skew [Auto] Adjusting this item may help enhancing BCLK overclocking ability. You may need to adjust the IOH Clock Skew item at the same time. Configuration options: [Auto] [Normal] [Delay 100ps]-[Delay 1500ps] ASUS P6T6 WS Revolution 3-23
