External Digi+ Power Control
CPU Input Boot Voltage [Auto]
This item allows you to set a higher CPU input boot voltage for better overclocking
capability. Use the <+> or <-> to adjust the value. The values range from 0.80V to 2.7V
with an interval of 0.01V.
CPU Load-line Calibration [Auto]
The load-line is defined by the Intel VRM specification and affects the CPU power
voltage. The CPU working voltage will decrease proportionally depending on the CPU
loading. Higher levels of the load-line calibration can get a higher voltage and a better
overclocking performance, but increase the CPU and VRM thermal production. Select
from levels 1 to 9 to adjust the CPU power voltage from 0% to 125%.
Configuration options [Auto] [Level 1] - [Level 9]
The actual performance boost may vary depending on your CPU specification.
DO NOT remove the thermal module. The thermal conditions should be monitored.
Internal CPU Power Management
The subitems in this menu allow you to set the CPU ratio and its features.
Turbo Mode [Enabled]
This item enables the CPU cores to run faster than the base operating frequency when
they are below the operating power, current and temperature specification.
Configuration options: [Disabled] [Enabled]
Extreme Over-voltage [Disabled]
Disable this item to protect the CPU from damage by over-voltage or enable to choose a high
voltage for overclocking.
Configuration options: [Disabled] [Enabled]
This item can only be enabled when the onboard CPU OverVoltage jumper is switched on.
Refer to section 1.1.2 Motherboard layout for the location of the CPU Overvoltage jumper.
CPU Core Voltage [Auto]
This item allows you to configure the amount of voltage fed to the CPU cores. Increase the
voltage when configuring a high CPU core frequency.
Configuration options: [Auto] [Manual Mode] [Offset Mode] [Adaptive Mode]
