MS-6799 ATX Mainboard
the default setting for long-term purpose. Settings: +0.00V~+0.20V
DDR 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. Settings: 2.50V~2.85V
North Bridge/South Bridge Voltage
These two items specifie the voltage of North Bridge Voltage and South Bridge
Voltage. Any changes made to these settings may cause a stability issue, so
changing the North Bridge/South Bridge Voltage for long-term purpose
is NOT recommended. Settings: 1.50V~1.80V(North), 2.50V~3.00V(South)
AGP Voltage
AGP voltage is adjustable in the field, allowing you to increase the perfor-
mance of your AGP display card when overclocking, but the stability may be
affected. Settings: 1.50V~2.20V
MSI Reminds You...
The settings shown in different color in CPU Volatage, DDR
Voltage, North Bridge/South Bridge Voltage and AGP Voltage
help to verify if your setting is proper for your system.

Auto Detect PCI/DIMM Clk
This option allows you to enable/disable the feature of auto detecting the clock
frequency of the installed PCI bus. The settings are: 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 Disable 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.
