f DRAM Frequency [Auto]
Sets the DRAM frequency. Please note the overclocking behavior is not guaranteed.
f Memory Try It ! [Disabled]
It can improve memory compatibility or performance by choosing optimized memory
preset.
f Advanced DRAM Configuration (optional)
Press Enter to enter the sub-menu. User can set the memory timing for each/ all
memory channel. The system may become unstable or unbootable after changing
memory timing. If it occurs, please clear the CMOS data and restore the default
settings. (Refer to the Clear CMOS jumper/ button (optional) section to clear the CMOS
data, and enter the BIOS to load the default settings.)
f DigitALL Power
Press Enter to enter the sub-menu. Controls the digital powers related to CPU PWM.
fCPU Loadline Calibration Control [Auto]
The CPU voltage will decrease proportionally according to CPU loading. Higher
load-line calibration could get higher voltage and good overclocking performance,
but increase the temperature of the CPU and VRM. If set to Auto, BIOS will
configure this setting automatically.
fCPU VRM Over Temperature Protection [Auto]
Sets the temperature limit on CPU VRM for over-temperature protection. The CPU
frequency may be throttled when CPU temperature over the specified temperature.
If set to Auto, BIOS will configure this settings.
fVR 12VIN OCP Expander [Auto]
Expands the limitation of VR Over Current Protection with 12V input voltage. The
higher expanding value indicates less protection. Therefore, please adjust the
current carefully if needed, or it may damage the CPU/ VR MOS. If set to "Auto",
BIOS will configure this setting automatically.
fDRAM CH_A/B / CH_C/D Phase Control [Auto]
Controls memory PWM phase according to the DRAM loading. If set to Auto, BIOS
will optimize the DRAM PWM phase automatically.
[Auto] This setting will be configured automatically by BIOS.
[Optimized] Sets the optimum PWM phase profile.
[Disabled] Disables the PWM phase switching feature.
fDRAM CH_A/B / CH_C/D Over Current Protection [Auto]
Sets the current limit for DRAM over-current protection. If set to Auto, BIOS will
configure this setting automatically.
[Auto] This setting will be configured automatically by BIOS.
[Enhanced] Extends the current range for over-current protection.
fDRAM CH_A/B / CH_C/D Switching Frequency [Auto]
Sets the PWM working speed to stabilize DRAM voltage and minimize ripple range.
Increasing the PWM working speed will cause higher temperature of MOSFET.
So please make sure a cooling solution is well-prepared for MOSFET before you
increase the value. If set to "Auto" , BIOS will configure this setting automatically.
