MSI Reminds You...
1. Even though the Dynamic Overclocking Technology is more stable
than manual overclocking, basically, it is still risky. We suggest
user to make sure that your CPU can afford to overclocking regu-
larly first. If you find the PC appears to be unstable or reboot
incidentally, it's better to disable the Dynamic Overclocking or to
lower the level of overclocking options. By the way, if you need to
conduct overclocking manually, you also need to disable the Dy-
namic OverClocking first.
2. Meanwhile, there are two functions to protect user's system from
crash.

Adjust CPU Clock Ratio
This item allows you to adjust the CPU ratio. Setting range is from [8X] to [50X].
Auto Detect PCI Clk
This item is used to auto detect the PCI slots. W hen set to [Enabled], the system will
remove (turn off) clocks from empty PCI slots to minimize the electromagnetic inter-
ference (EMI). Settings: [Enabled], [Disabled].
Spread Spectrum
W hen 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,
select the desired range for EMI reduction. Remember to disable Spread Spectrum
function if you are overclocking, because even a slight jitter can introduce a tempo-
rary boost in clock speed which may just cause your overclocked processor to lock
up.
CPU Clock
This item specifies the clock frequency of CPU host bus (FSB), AGP (3V66) and PCI
bus. It provides a method for end users to overclock the processor. Setting options:
Give a DEC value by entering a number between maximum [200] MHz to minimum
[100] MHz.
CPU Voltage
The settings are used to adjust the CPU clock multiplier (ratio) and CPU corevoltage
(Vcore). These settings offer users a tool to overclock the system.
There is a safe key "Ins" in BIOS. In case the overclocking
fails, you can press "Ins" key while system rebooting to
restore to the BIOS defaults.
If the system incidentally reboot for four times, the BIOS will
also be restored to the defaults.
