CPU PLL Voltage [Auto]

Allows you to set the CPU PLL voltage. The values range from 1.50V to 2.78V with a 0.02V interval.

FSB Termination Voltage [Auto]

Allows you to set the front side bus termination voltage. The values range from 1.20V* to 1.90V with a 0.02V interval.

*The minimum value of this item becomes 1.10V when a 45nm CPU is installed.

Memory Voltage [Auto]

Allows you to set the memory voltage. The values range from 1.80V to 3.08V with a 0.02V interval.

NB Voltage [Auto]

Allows you to set the North Bridge voltage. The values range from 1.10V to 2.06V* with a 0.02V interval.

•The value [2.06V] of the NB Voltage item is supported only if the OV_NB jumper is enabled, otherwise the maximum voltage supported is [1.76V]. See 2. CPU / Northbridge overvoltage setting on page 2-20 for details.

•Setting the CPU PLL Voltage, FSB Termination Voltage, Memory 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 CPU PLL Voltage, FSB Termination Voltage, Memory 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.
