Chapter 3
CPU VCore Bootup 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 1.990V with a 0.005V interval. The values range from 0.800V to 1.990V with a 0.005V interval.
CPU VSA
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%] [140%]
VCCSA Fixed Frequency [XXX]
The values range from 300kHz to 600kHz with a 50kHz interval.
CPU VSA Bootup Voltage [Auto]
[Auto]
This item controls the voltage for CPU VSA at initial boot. Set higher value for better
overclockability. The values range from 0.800V to 1.990V with a 0.005V interval. The values range from 0.800V to 1.990V with a 0.005V interval.
CPU VTT
CPU VTT Switching Freq [Auto]
This item allows you to switch the frequency of VTT power. Set 1.3x for cleaner power.
Configuration options: [Auto] [1x] [1.3x]
CPU VTT Over-Current Protection [Auto]
This item allows you to enable or disable the CPU VTT over-current protection. Set to
[Disabled] to remove over-current protection on VTT power.
Configuration options: [Auto] [Enabled] [Disabled]
DRAM Voltage
DRAM-AB/DRAM-CD Current Capability [100%]
Setting a higher value brings a wider total power range and extends the overclocking
frequency range simultaneously.
Configuration options: [100%] [110%] [120%] [130%] [140%]
DRAM-AB/DRAM-CD Voltage Frequency [Auto]
This item allows you to adjust the DRAM switching frequency. Assign a fixed high
DRAM frequency to increase O.C range or a lower DRAM frequency for better system
stability. Configuration options: [Auto] [manual] Configuration options: [Auto] [manual]
DRAM-AB/DRAM-CD Power Phase control [Auto]
[Optimized] Allows you to set ASUS optimized phase tuning profile.
[Extreme] Allows you to set the Full phase mode.
PCH 1.1V
PCH 1.1v Switching Freq. [Auto]
This item allows you to switch the frequency of PCH power. Set 1.3x for cleaner power.
Configuration options: [Auto] [1x] [1.3x]
