2.4.8NB Clock Skew [Auto]

Allows you to set the Northbridge chipset clock skew.

Configuration options: [Auto] [Normal] [Delay 100ps] [Delay 200ps] [Delay 300ps] [Delay 400ps] [Delay 500ps] [Delay 600ps] [Delay 700ps] [Delay 800ps] [Delay 900ps] [Delay 1000ps] [Delay 1100ps] [Delay 1200ps] [Delay 1300ps] [Delay 1400ps] [Delay 1500ps]

2.4.9CPU Voltage [Auto]

Allows you to set the CPU VCore voltage. The values range from 0.85000V to 1.60000V* with a 0.00625V interval. Press +/- to adjust the value.

Refer to the CPU documentation before setting the CPU Vcore voltage. Setting a high VCore voltage may damage the CPU permanently, and setting a low VCore voltage may make the system unstable.

2.4.10CPU PLL Voltage [Auto]

Allows you to set the CPU PLL voltage. The values range from 1.50V to 1.60V with a 0.10V interval. Press +/- to adjust the value.

2.4.11FSB Termination Voltage [Auto]

Allows you to set the front side bus termination voltage. The values range from 1.10V* to 1.20V with a 0.10V interval. Press +/- to adjust the value.

2.4.12DRAM Voltage [Auto]

Allows you to set the DRAM voltage. The values range from 1.80V to 2.15V with a 0.05V interval. Press +/- to adjust the value.

2.4.13NB Voltage [Auto]

Allows you to set the North Bridge voltage. The values range from 1.10V to 1.40V with a 0.10V interval. Press +/- to adjust the value.

Setting the CPU PLL Voltage, 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 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.
