3.4.12CPU Voltage [Auto]

Allows you to set the CPU VCore voltage. The values range from 0.85000V to 2.10000V* with a 0.00625V interval.

•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.

•The value [2.10000V] of the CPU Voltage item is supported only if the

OV_CPU jumper is enabled, otherwise the maximum voltage supported is [1.70000V]. See 2. CPU / Northbridge overvoltage setting on page 2-19 for details.

3.4.13CPU GTL Voltage Reference(0/2) [Auto]

Allows you to set the CPU GTL voltage reference. The values range from 0.370x to 0.760x with a 0.005x interval. Different ratio might enhance CPU overclocking ability.

3.4.14CPU GTL Voltage Reference(1/3) [Auto]

Allows you to set the CPU GTL voltage reference. The values range from 0.410x to 0.800x with a 0.005x interval. Different ratio might enhance CPU overclocking ability.

3.4.15CPU 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.

3.4.16FSB 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.

3.4.17DRAM Voltage [Auto]

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

3.4.18NB Voltage [Auto]

Allows you to set the North Bridge voltage. The values range from 1.10V to 2.2V* with a 0.02V interval.
