2-16 ASUS Z87-A
2.5.10 OC Tuner [As Is]
OC Tuner automatically overclocks the frequency and voltage of CPU and DRAM for
enhancing the system performance and accelerates the iGPU performance to the extreme
according to the integrated graphics loading.
Configuration options: [As Is] [Ratio Only] [BCLK First]
2.5.11 EPU Power Saving Mode [Disabled]
Allows you to enable or disable the EPU power saving function.
Configuration options: [Disabled] [�nabled]
2.5.12 DRAM Timing Control
The subitems in this menu allow you to set the DRAM timing control features. Use the <+> or
<-> keys to adjust the value. To restore the default setting, type [auto] using the keyboard and
press the key.
Changing the values in this menu may cause the system to become unstable! If this
happens, revert to the default settings.
2.5.13 DIGI+ VRM
CPU Load-Line Calibration [Auto]
Load�line is defined by Intel ® VR� specification and affects CPU power voltage. The CPU
working voltage will decrease 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 Level 1 to Level 8 to adjust CPU power voltage from 0% to 100%.
The actual performance boost may vary depending on your CPU specification.
DO NOT remove the thermal module. The thermal conditions should be monitored.
CPU Voltage Frequency [Auto]
Frequency switching affects the VRM transient response and the thermal component
conditions. Higher frequency gets quicker transient response.
Configuration options: [Auto] [�anual]
DO NOT remove the thermal module when setting this item to [Manual Mode]. The thermal
conditions should be monitored.
The following item appears only when you set the CPU Voltage Frequency to [Manual].
CPU Fixed Frequency [300]
This item allows you to set a fixed CPU Voltage frequency. Use the <+> or <�> keys to
adjust the value. The values range from ���k�z to 5��k�z with a 5�k�z interval.
