• Setting the CPU PLL Voltage, FSB Termination Voltage, DRAM Voltage and North Bridge Voltage to a high level may damage the chipset, memory module, and CPU permanently. Proceed with caution. • Some values of the CPU PLL Voltage, FSB Termination Voltage, DRAM Voltage and North Bridge 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. Blue CPU PLL Voltage 1.50V~1.78V FSB Termination Voltage 1.20V~1.38V DRAM Voltage 1.80V~1.98V North Bridge Voltage 1.25V~1.41V Yellow 1.80V~2.00V 1.40V~1.50V 2.00V~2.20V 1.43V~1.55V Purple 2.02V~2.20V N/A 2.22V~2.40V 1.57V~1.73V Red 2.22V~2.78V N/A 2.42V~3.08V 1.75V~1.91V South Bridge Voltage [Auto] Allows you to select the south bridge voltage.
