Asus Z170M-E D3 User Manual

2.5.10 DRAM Timing Control
The subitems in this menu allow you to set the DRAM timing control features. Use the
<+> and <-> keys to adjust the value. To restore the default setting, type [auto] using the
keyboard and press the <Enter> key.
Changing the values in this menu may cause the system to become unstable! If this
happens, revert to the default settings.
2.5.11 DIGI+ VRM
CPU Load-Line Calibration [Auto]
Load-line is dened by Intel VRM specication 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 increases the CPU and VRM thermal. Select from level 1 to 7 to adjust the CPU power
voltage from 0% to 100%. Conguration options: [Auto] [Level 1] [Level 2] [Level 3] [Level 4]
[Level 5] [Level 6] [Level 7]
The boosted performance may vary depending on the CPU specication. Do not remove
the thermal module.
CPU Current Capability [Auto]
Allows you to congure the total power range, and extends the overclocking frequency range
simultaneously. Conguration options: [Auto] [100%] [110%] [120%] [130%] [140%]
Choose a higher value when overclocking, or under a high CPU loading for extra power
support.
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.
The following item appears only when you set the CPU VRM Switching Frequency to
[Manual].
Fixed CPU VRM Switching Frequency (KHz) [250]
This item allows you to set a higher frequency for a quicker transient response speed.
Use the <+> and <-> keys to adjust the value. The values range from 250KHz to
500KHz with a 50KHz interval.
CPU Power Duty Control [T.Probe]
DIGI + VRM Duty control adjusts the current and thermal conditions of every component’s
phase.
[T. Probe] Select to maintain the VRM thermal balance.
[Extreme] Select to maintain the current VRM balance.
