tRRd
When the dRaM timing Mode sets to [Manual], the field is adjustable. Speci-
fies the active-to-active delay of different banks.
tWtR
When the dRaM timing Mode is set to [Manual], the field is adjustable. this
item controls the Write data in to Read Command delay memory timing. this
constitutes the minimum number of clock cycles that must occur between the
last valid write operation and the next read command to the same internal bank
of the ddR device.
FSB/dRaM Ratio
this item will allow you to adjust the ratio of FSB to memory.
adjusted dRaM Frequency (MHz)
it shows the adjusted memory frequency. Read-only.
adjust PCi-e Frequency (MHz)
this item allows you to adjust the PCi-e frequency.
auto disable dRaM/PCi Frequency
When set to [enabled], the system will remove (turn off) clocks from empty diMM
and PCi slots to minimize the electromagnetic interference (eMi).
Spread Spectrum
When the motherboard's clock generator pulses, the extreme values (spikes) of
the pulses create eMi (electromagnetic interference). the Spread Spectrum func-
tion 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 proces-
sor 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.
