▶ Advance DRAM Configuraton
Press <Enter> to enter the sub-menu.
▶ DRAM Tmng Mode
Ths tem allows you to select the DDR tmng settng. Settng to [Auto] enables
memory clock automatcally to be determned by SPD. Selectng [Manual] allows
users to configure these fields manually.
▶ FSB/DRAM Rato
Ths tem wll allow you to adjust the rato of FSB to memory.
▶ Adjusted DRAM Frequency (MHz)
It shows the adjusted DDR Memory frequency. Read-only.
▶ Adjust PCI-E Frequency (MHz)
Ths field allows you to select the PCIE frequency (n MHz).
▶ Auto Dsable DRAM/PCI Frequency
When set to [Enabled], the system wll remove (turn off) clocks from empty DIMM and
PCI slots to mnmze the electromagnetc nterference (EMI).
▶ CPU Voltage (V)/ CPU GTL REF0 (V)/ CPU GTL REF1 (V)/ DRAM Voltage (V)/ NB
Voltage (V)/ VTT FSB Voltage (V)/ ICH Voltage (V)
These tems are used to adjust the voltage of CPU, Memory and chpset.
▶ Spread Spectrum
When the manboard's clock generator pulses, the extreme values (spkes) of the pulses
create EMI (Electromagnetc Interference). The Spread Spectrum functon reduces the
EMI generated by modulatng the pulses so that the spkes of the pulses are reduced to
flatter curves. If you do not have any EMI problem, leave the settng at Dsabled for opt-
mal system stablty and performance. But f you are plagued by EMI, set to Enabled for
EMI reducton. Remember to dsable Spread Spectrum f you are overclockng because
even a slght jtter can ntroduce a temporary boost n clock speed whch may just cause
your overclocked processor to lock up.

stablty and performance. But f you are plagued by EMI, select the value of Spread
Spectrum for EMI reducton.
The greater the Spread Spectrum value s, the greater the EMI s reduced, and the
•
system wll become less stable. For the most sutable Spread Spectrum value, please
consult your local EMI regulaton.

clocked processor to lock up.
