Frequency/Voltage Control - MSI MS-7031 User Manual

BIOS Setup

Frequency/Voltage Control

Use this menu to specify your settings for frequency/voltage control.
Current CPU FSB Clock/DRAM Clock
These two items show the current clocks of CPU/DRAM. Read-only.
CPU Clock Ratio
This setting controls the multiplier that is used to determine the internal clock speed of
the processor relative to the external or motherboard clock speed.
Auto Detect PCI Clock
This feature enables the BIOS to auto detect PCI device and set PCI slot clock. Setting
options are: [Enabled], [Disabled].
Memory Voltage
Adjusting the DDR voltage can increase the DDR speed. Any changes made to
this setting may cause a stability issue, so changing the DDR voltage for
long-term purpose is NOT recommended.
AGP/IGP Voltage
AGP voltage and IGP (integrated Graphic, the NorthBride built-in graphics controller)
voltage are both adjustable in their individual fields, allowing you to increase the
performance of your AGP display card/integrated graphics when overclocking,
but the stability may be affected, so changing the AGP/IGP voltage for long-
term purpose is NOT recommended.
Spread Spectrum
When the motherboard's clock generator pulses, the extreme values (spikes) of the
pulses creates EMI (Electromagnetic Interference). The Spread Spectrum function
reduces the EMI generated by modulating the pulses so that the spikes of the pulses
are reduced to flatter curves. If you do not have any EMI problem, leave the setting at
[Disabled] for optimal system stability and performance. But if you are plagued by EMI,
activate the Spread Spectrum for EMI reduction. Remember to disable Spread
