2.4.6 DRAM Timing Control
The sub-items in this menu allow you to set the DRAM timing control features. Use the <+>
and <-> keys to adjust the value. To restore the default setting, type [auto] using the keyboard
and press <Enter>.
Changing the values in this menu may cause the system to become unstable! If this
happens, revert to the default settings.
2.4.7 APU Voltage [Offset Mode]
[Offset Mode] To offset the voltage by a positive or negative value.
CPU Offset Mode Sign [+]
[+] To offset the voltage by a positive value.
[–] To offset the voltage by a negative value.
CPU Offset Voltage [Auto]
Allows you to set the CPU Offset voltage. The values range from 0.00625V to 0.500V 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.
VDDNB Offset Mode Sign [+]
[+] To offset the voltage by a positive value.
[–] To offset the voltage by a negative value.
VDDNB Offset Voltage [Auto]
Allows you to set the VDDNB Offset voltage. The values range from 0.00625V to 0.500V with
a 0.00625V interval.

Allows you to set the DRAM voltage. The values range from 1.35V to 1.65V with a 0.15V
interval.
2.4.9 SB 1.1V Voltage [Auto]
Allows you to set the Southbridge 1.1V voltage. The values range from 1.1V to 1.22V with a
0.04V interval.
• The values of the CPU Offset Voltage , VDDNB Offset Voltage , DRAM Voltage , and
SB 1.1V Voltage items are labeled in a different color, indicating the risk levels of high
voltage settings.
• The system may need a better cooling system to work properly under high voltage
settings.
