! Multiplier Factor:

This item displays the multiplier factor for the CPU you installed.

NOTE: Some processors might have this multiplier factor locked, so there is no way to choose a higher

multiplier factor.

! External Clock:

This item selects the external clock frequency. Due to the specification limit of the CPU you installed, the

speed you set over its standard bus speed is supported, but not guaranteed.

! Estimated New CUP Clock

This item estimates the new CPU clock when the next time the system starts. The value is decided by the

values of “Multiplier Factor” and “External Clock”.

! PCIE Clock

This item selects the PCI Express frequency.

Voltages Control:

This option allows you to switch between the default and user-defined voltages. Leave this setting to

default unless the current voltage setting cannot be detected or is not correct. The option “User Define”

enables you to select the following voltages manually.

! CPU Voltage:

This item selects the CPU core voltage.

! NB 1.8V Voltage:

This item selects the NB 1.8V voltage.

! DDR Voltage:

This item selects the voltage for DRAM slot.

! HyperTransport Voltage:

This item selects the voltage for LDT Bus.

! NB 1.2V Voltage:

This item selects the NB 1.2V voltage.

DDR Reference Voltage:

This Item selects the voltage for DDR memory reference.
