DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.50V to 3.10V with a
0.02V interval.
NB Voltage [Auto]
Allows you to set the North Bridge voltage. The values range from 1.30V to 2.00V
with a 0.02V interval.
• Setting the FSB Termination Voltage, DRAM Voltage and NB Voltage
items to a high level may damage the chipset, memory module and CPU
permanently. Proceed with caution.
• Some values of the FSB Termination Voltage, DRAM Voltage and NB
Voltage items are labeled in different color, indicating the risk levels of high
voltage settings. Refer to the table below for details.
• The system may need better cooling system to work stably under high
voltage settings.
