BIOS Setup
! Multiplier Factor:
This item displays the multiplier factor for the CPU you installed.
! CPU FSB Clock(MHz):
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.
!
AGP Clock(MHz):
This item allows you to set the AGP clock speed from 66MHz to 75MHz. Due to the AGP specification
limit, the speed you set over its standard clock speed is supported, but not guaranteed.
Voltage 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 Core Voltage:
This item selects the CPU core voltage.
! DDR Voltage:
This item selects the voltage for DRAM slot.
! DDR Ref Voltage:
This item selects the reference voltage needed for DRAM slot to increase its conformity.
! AGP Voltage:
This item selects the voltage for AGP slot.
! Chipset Voltage:
This item selects the Chipset voltage.
ATTENTION: A wrong voltage setting may cause the system unstable or even damage the CPU. Please
leave it to default settings unless you are fully aware of its consequences.
Spread Spectrum:
For EMC (Electro-Magnetic Compatibility) testing, you may need to adjust these options for optimal
results. We do not recommend you change the default, except for special reasons. Some values you select
may cause system instability under some situations. Please be careful.
