Chapter 4 - BIOS Setup
4-21
Use this menu to specify your settings for frequency/voltage control.
Cell Menu
Current CPU Clock
The item shows the current status of CPU Frequency.
Cool’n’Quiet control
This feature is especially desiged for AMD Athlon processor, which provides a CPU
temperature detecting function to prevent your CPU’s from overheading due to the
heavy working loading. Setting options: [Disabled], [Auto].
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. Setting options: [2.5] to [2.85].
AGP Voltage
AGP voltage is adjustable in the field, allowing you to increase the performance of your
AGP display card when overclocking, but the stability may be affected.
With AGP card installed Default value= [1.50 V]
Without AGP card installed Default value= [1.70 V]
Auto Detect PCI Clk
This item is used to auto detect the PCI slots. When set to [Enabled], the system will
remove (turn off) clocks from empty PCI slots to minimize the electromagnetic interfer-
ence (EMI). Setting options: [Enabled], [Disabled].
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,
set to [Enabled] for EMI reduction. Remember to disable Spread Spectrum if you are
overclocking because even a slight jitter can introduce a temporary boost in clock
speed which may just cause your overclocked processor to lock up. Setting options:
[Enabled], [Disabled].
MSI Reminds You...
For the purpose of ensuring the stability of Cool'n'Quiet function, it is
always recommended to have the memories plugged in DIMM1.
