VDDNB Manual Voltage [Auto]
This item appears only when you set the CPU Voltage item to [Manual Mode] and
allows you to set a xed VDDNB voltage. The values range from 0.800V to 1.750V with
a 0.00625V interval.
DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.35V to 2.135V with a 0.005V
interval.
SB 1.1V Voltage [Auto]
Allows you to set the Southbridge 1.1V voltage. The values range from 1.1V to 1.4V with a
0.01V interval.
1.1VSB Voltage [Auto]
Allows you to set the 1.1Vsb voltage. The values range from 1.1000V to 1.4000V with a 0.1V
interval.
APU1.2V Voltage [Auto]
Allows you to set the APU (Accelerated Processor Unit) 1.2V voltage. The values range from
1.2000V to 1.8000V with a 0.01V interval.
VDDA Voltage [Auto]
Allows you to set the VDDA voltage. The values range from 2.5000V to 2.8000V with a 0.1V
interval.
NB VREF Voltage [Auto]
Allows you to set the NB VREF voltage with a 0.005V interval.
DRAM VREFCA Voltage [Auto]
Allows you to set the DRAM VREFCA voltage with a 0.005V interval.
DRAM VREFDQ Voltage [Auto]
Allows you to set the DRAM VREFDQ voltage with a 0.005V interval.
• The values of the CPU Offset Voltage, CPU Manual Voltage, VDDNB Offset Voltage,
VDDNB Manual Voltage, DRAM Voltage, SB 1.1V Voltage, 1.1VSB Voltage, APU1.2V
Voltage, VDDA Voltage, NB VREF Voltage, DRAM VREFCA Voltage, and DRAM
VREFDQ Voltage items are labeled in different color, indicating the risk levels of high
voltage settings.
• The system may need better cooling system to work stably under high voltage settings.
