Chapter 2: BIOS information 2-15
CPU Voltage [Auto]
Allows you to set the CPU Offset voltage. The values range from -0.3V to +0.5V with a
0.00625V interval.
Refer to the CPU documentation before setting the CPU voltage. Setting a high voltage
may damage the CPU permanently, and setting a low voltage may make the system
unstable.
2.4.7 VDDNB Offset Mode Sign [+]
[+] To offset the voltage by a positive value.
[–] To offset the voltage by a negative value.
VDDNB Voltage [Auto]
Allows you to set the VDDNB Offset voltage. The values range from -0.3V to +0.5V with a
0.00625V interval.
2.4.8 DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.35V to 2.30V with a 0.01V
interval. Use the <+> and <-> keys to adjust the value.
2.4.9 SB 1.1V Voltage [Auto]
Allows you to set the Southbridge 1.1V voltage. The values range from 1.1V to 1.3V with a
0.01V interval.
2.4.10 APU 1.8V Voltage [Auto]
Allows you to set the APU (Accelerated Processor Unit) 1.8V voltage. The values range from
1.8000V to 1.9000V with a 0.1V interval.
2.4.11 APU 1.05V Voltage [Auto]
Allows you to set the APU 1.05V voltage. The values range from 1.0500V to 1.2500V with a
0.01V interval.
• The values of the CPU Voltage, VDDNB Voltage, DRAM Voltage, SB 1.1V Voltage,
APU 1.8V Voltage, and APU 1.05V 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.
2.4.12 APU Spread Spectrum [Auto]
[Auto] Automatic conguration.
[Disabled] Enhances the PCIE overclocking ability.
[Enabled] Sets to [Enabled] for EMI control.
