Select values 2 to 4 for best memory overclocking.

Configuration options: [Auto] [0] - [7]

recommendations, SPD write disable must be set.

Configuration options: [TRUE] [FALSE]

CPU Load-line Calibration

Load-line is defined by Intel

specification 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.

Configuration options [Auto] [Level 1] - [Level 7]

The actual performance boost may vary depending on your CPU specification.

DO NOT remove the thermal module. The thermal conditions should be monitored.

Synch ACDC Loadline with VRM Loadline

Enable this item to allow the VRM Loadline to be adjusted automatically to match the

AC/DC Loadline.

Configuration options: [Enabled] [Disabled]

CPU Current Capability

This item allows you to set the shut off current limit for external voltage regulator. A

higher setting will allow the voltage regulator to supply more current while a lower

setting will cause the voltage regulator to shut off the system when the supplied

current is higher than the set value.

Configuration options: [Auto] [100%] - [170%]

Configure higher values when overclocking or under a high loading for extra power

support.

CPU VRM Switching Frequency

This item affects the VRM transient response speed and the component thermal

production. Select [Manual] to configure a higher frequency for a quicker transient

response speed.

Configuration options: [Auto] [Manual]

DO NOT remove the thermal module. The thermal conditions should be monitored.
