3.3.20 NB Voltage [Auto]

Allows you to set the NB voltage. The values range from 1.11300V to 2.00075V

with a 0.01325V interval. The text color in the configuration field indicates voltage

The text color in the configuration field indicates voltage

condition. When you set the NB LED Selection item to [North Bridge Voltage], the

onboard northbridge LED displays northbridge voltage condition.

• The value [2.21V] of the NB Voltage item is supported only if the OV_NB

jumper is enalbed, otherwise the maximum voltage suppoted is [1.91V].

• Setting the CPU Voltage, CPU/NB Voltage, CPU VDDA 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 CPU PLL Voltage, 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.
