CPU Load Line Calibration [Auto]
Load-line Calibration is dened by AMD VRM specications and affects CPU voltage. The
CPU working voltage will decrease proportionally to CPU loading. Higher load-line calibration
would get higher voltage and better overclocking performance, but increase the CPU and
VRM thermal. This item allows you to adjust the voltage range from the following percentages
to boost the system performance: 0% (Regular), 60% (Medium), 80% (High), and 100%
(Extreme). Conguration options: [Auto] [Regular] [Medium] [High] [Extreme]
The actual performance boost may vary depending on your CPU speciation.
CPU/NB Load Line Calibration [Auto]
Allows you to select the CPU/NB Load-Line Calibration mode. Conguration options: [Auto]
[Regular] [High] [Extreme]
CPU Current Capability [100%]
This item provides wider total power range for overclocking. A higher value brings a
wider total power range and extends the overclocking frequency range simultaneously.
Conguration options: [100%] [110%] [120%] [130%]
CPU/NB Current Capability [100%]
This item provides wider total power range for overclocking. A higher value brings a
wider total power range and extends the overclocking frequency range simultaneously.
Conguration options: [100%] [110%] [120%] [130%]
CPU Power Phase Control [Standard]
Phase number is the number of working VRM phase. Increasing phase number under heavy
system loading to get more transient and better thermal performance. Reducing phase
number under light system loading to increase VRM efciency.
[Standard] Proceeds phase control depending on the CPU loading.
[Optimized] Loads the ASUS optimized phase tuning prole.
[Extreme] Proceeds the full phase mode.
[Manual Adjustment] Allows manual adjustment.
DO NOT remove the thermal module when switching to Extreme and Manual Adjustment.
The thermal conditions should be monitored.
Manual Adjustment [Fast]
This item appears only when you set the previous item to [Manual Adjustment]. Select [Ultra
Fast] for a faster response. The reaction time will be longer when [Regular] is selected.
Conguration options: [Ultra Fast] [Fast] [Medium] [Regular]
CPU Voltage Frequency [300]
Switching frequency will affect the VRM transient response and component thermal. Setting
a higher frequency gets faster transient response. Use the <+> and <-> keys to adjust the
value. The values range from 200k Hz to 350k Hz with a 50k Hz interval.
