2-14 Chapter 2: BIOS information
CPU Clock Skew [Auto]
Adjusting this item may help enhancing BCLK overclocking ability. You may need to adjust the
NB Clock Skew item at the same time.
Configuration options: [Auto] [Normal] [Delay 100ps]–[Delay 1500ps]
VCore Over Voltage [Auto]
Allows you to set the CPU vCore over voltage. Use the <+> and <-> keys to adjust the value.
Configuration options: [Auto] [Max.=0.63V] [Min.=0.01V]
Refer to the CPU documentation before setting the CPU vCore voltage. Setting a high
voltage may damage the CPU permanently, and setting a low voltage may make the system
unstable.
IMC Voltage [Auto]
Allows you to set the CPU Integrated Memory Controller voltage. Use the <+> and <-> keys to
adjust the value. Configuration options: [Auto] [Max.=1.45V] [Min.=1.10V]
DRAM Voltage [Auto]
Allows you to set the DRAM voltage. Use the <+> and <-> keys to adjust the value.
Configuration options: [Auto] [Max.=2.145V] [Min.=1.200V]
CPU PLL Voltage [Auto]
Allows you to set the CPU PLL voltage. Use the <+> and <-> keys to adjust the value.
Configuration options: [Auto] [Max.=2.100V] [Min.=1.800V]
PCH Voltage [Auto]
Allows you to set the Platform Controller Hub voltage. Configuration options: [Auto]
[Max.=1.155V] [Min.=1.050V]
• The values of the IMC Voltage, DRAM Voltage, and CPU PLL Voltage items are labeled
in different color, indicating the risk levels of high voltage settings. Refer to the table
below for details.
• The system may need better cooling system to work stably under high voltage settings.
DRAM DATA REF Voltage on CHA/B [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.
Load-Line Calibration [Auto]
[Auto] Automatic configuration.
[Disabled] Follow Intel specifications.
[Enabled] Improve CPU VDroop directly.
