Chapter 3: BIOS setup
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.
Conguration options: [100%] [110%] [120%] [130%]
CPU VCCSA Boot Up Voltage [Auto]
This adjusts the voltage for VCCSA at initial boot up. Set to higher values for better
overclocking results.
Use the <+> and <-> keys to adjust the value. The values range from 0.800 to 1.700 with
0.005 interval.
CPU Voltage Frequency [Auto]
Switching frequency will affect the transient response and component thermal. Setting a
higher frequency gets faster transient response.
[Auto] Allows you to enable or disable the
CPU Spread Spectrum item.
[Manual] Allows you to manually set the
CPU Fixed Frequency from 300k~500kHz
with a 10k Hz interval.
CPU Spread Spectrum [Disabled]
This item appears when you set the CPU Voltage Frequency item to [Auto]. Enable the
Spread Spectrum to enhance system stability.
Conguration options: [Enabled] [Disabled]
CPU Fixed Frequency [300]
This item appears when you set the CPU Voltage Frequency item to [Manual].
Use the <+> and <-> keys to adjust the value. The values range from 300k~500kHz with
a 10k Hz interval.
Do not remove the thermal module when switching to Manual mode. The thermal
conditions should be monitored.
CPU Power Duty Control [T.Probe]
CPU Power Duty Control adjusts current and thermal of every phase component.
[T.Probe] Maintains thermal balance.
[Extreme] Maintains current balance.
Do not remove the thermal module. The thermal conditions should be monitored.
CPU Power Phase Control [Auto]
Controls current capability and voltage frequency through different modes. Increase phase
number under heavy system loading to get more transient and better thermal performance.
Reduce phase number under light system loading to increase efciency
[Auto] Proceeds preset phase control.
[Standard] Proceeds phase control based on CPU Command.
[Optimized] Loads the ASUS optimized phase tuning prole.
[Extreme] Proceeds the full phase mode.
[Manual Adjustment] Allows manual adjustment. Phase number adjusted by
current(A) step.
