This item will allow you to adjust the PCI Express voltage.
Spread Spectrum
When the mainboard’s clock generator pulses, the extreme values (spikes) of the pulses create 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
slighter jitter can introduce a temporary boost in clock speed which may just cause your overclocked processor
to lock up.
NOTE
1. If you do not have any EMI problem, leave the setting at [Disabled] for optimal system stability and
performance. Bit if you are plagued by EMI, select the value of Spread Spectrum for EMI reduction.
2.
The greater the Spread Spectrum value is, the greater the EMI is reduced, and the system will become less
stable. For the most suitable Spread Spectrum value, please consult your local EMI regulation.
3.
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.
Load Fail-Safe/Optimized Defaults
The two options on the main menu allow users to restore all of the BIOS settings to the default Fail-Safe or
Optimized values. The Optimized Defaults are the default values set by the mainboard manufacturer specifically
for optimal performance of the mainboard. The Fail-Safe Defaults are the default values set by the BIOS vendor
for stable system performance.
When you select Load Fail-Safe Defaults, a message appears as below:
Pressing [Ok] loads the BIOS default values for the most stable, minimal system performance.
When you select Load Optimized Defaults, a message as below appears:
Pressing [Ok] loads the default factory settings for optimal system performance.
