ht Link Speed
this item allows you to set the hyper-transport Link speed. Setting to [Auto], the
system will detect the ht link speed automatically.
Adjusted ht Link Frequency (Mhz)
it shows the adjusted ht Link frequency. read-only.
Auto disable drAM/PCi Frequency
When set to [enabled], the system will remove (turn off) clocks from empty drAM/
PCi slots to minimize the electromagnetic interference (eMi).
CPu Vdd Voltage (V)/ CPu-NB Vdd Voltage (V)/ drAM Voltage (V)
these items are used to adjust the voltage of CPu, Memory and chipset.
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 slight jitter can introduce a tem-
porary boost in clock speed which may just cause your overclocked processor
to lock up.
iMPortANt
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
value of Spread Spectrum for eMi reduction.
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.
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.
