External Digi+ Power Control
CPU Load-line Calibration [Auto]
Load-line is dened by Intel
®
specication and affects CPU power voltage. The CPU
working voltage decreases proportionally to CPU loading. Higher load-line calibration
could get higher voltage and good overclocking performance, but increases the CPU
and VRM thermal conditions. Select from levels 1 to 9 to adjust the CPU power voltage
from 0% to 125%.
Conguration options [Auto] [Level 1] - [Level 9]
The actual performance boost may vary depending on your CPU specication.
DO NOT remove the thermal module. The thermal conditions should be monitored.
CPU VRM Switching Frequency [Auto]
This item affects the VRM transient response speed and the component thermal
production. Select [Manual] to congure a higher frequency for a quicker transient
response speed.
Conguration options: [Auto] [Manual]
DO NOT remove the thermal module. The thermal conditions should be monitored.
