3.5.14

CPU GTL Reference [Auto]

Allows you to set the CPU GTL reference voltage. Different ratio might enhance CPU
overclocking ability. Configuration options: [Auto] [0.65x] [0.63x] [0.61x]
The following six (6) items are adjusted by typing the desired values using the numeric keypad
and press the <Enter> key. You can also use the <+> and <-> keys to adjust the value. To
restore the default setting, type [auto] using the keyboard and press the <Enter> key.
3.5.15

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.
3.5.16

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.
3.5.17

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 overvoltage setting on page 2-22 for details.
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 Voltage, 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 on the next page for details.
The system may need better cooling system to work stably under high voltage
settings.
