The actual performance boost may vary depending on your CPU specification.
CPU Current Capability [Auto]
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.
Configuration options: [Auto] [100%] [110%] [120%] [130%] [140%]
CPU VCORE Boot Up Voltage [Auto]
This item controls the voltage for CPU at initial boot. Set higher value for better
overclockability. The values range from 0.800V to 1.700V with a 0.005V interval.
VCCSA Load-line calibration [Auto]
The behavior of the DRAM controller is decided by VCCSA Load-Line. Set to a higher
value for system performance, or to a lower value for better thermal solution.
Configuration options: [Auto] [Regular] [High] [Extreme]
VCCSA Current Capability [100%]
Allows you to set the VCCSA current capability. A higher value brings wider total DRAM
controller power range and extends the overclocking frequency range simultaneously.
Configuration options: [100%] [110%] [120%] [130%]
CPU VCCSA Boot Up Voltage [Auto]
This item controls the voltage for CPU VCCSA at initial boot. Set higher value for better
overclockability. The values range from 0.800V to 1.700V with a 0.005V interval.
CPU Voltage Frequency [Auto]
Switching frequency will affect the transient response and component thermal. Higher
frequency gets quicker transient response.
Configuration options: [Auto] [Manual]
CPU Fixed Frequency [XXX]
This item appears only when you set the CPU Voltage Frequency item to [manual]
and allows you to set a CPU fixed frequency. The values range from 300kHz to 500kHz
with a 10kHz interval.
CPU Spread Spectrum [Diasbled]
[Disabled] Enhances the BCLK overclocking ability.
[Enabled]
CPU Power Duty Control [T.Probe]
[T.Probe]
[Extreme] Maintains the VRM current balance.
CPU Power Phase Control [Auto]
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 efficiency
[Auto]
[Standard]
[Optimized]
[Extreme]
[Manual Adjustment]
3-12
Sets to [Enabled] for EMI control.
Maintains the VRM thermal balance.
Loads the settings for the system automatically.
Proceeds phase control depending on the CPU loading.
Loads the ASUS optimized phase tuning profile.
Proceeds the full phase mode.
Allows manual adjustment for Regular/Medium/Fast/Ultra
Fast options.
