▶ MemClk Tristate C3/ATLVID
This setting allows you to enable/disable the MemClk Tristating during C3 and
ATLVID.
▶ FSB/DRAM Ratio
This item allows you to select the ratio of FSB/ DRAM.
▶ Adjusted DRAM Frequency (MHz)
It shows the adjusted Memory frequency. Read-only.
▶ HT Link Control
Press <Enter> to enter the sub-menu.
▶ HT Incoming/ Outgoing Link Width
These items allow you to set the Hyper-Transport Link width. Setting to [Auto], the
system will detect the HT link width automatically.
▶ HT Link Speed
This item allows you to set the Hyper-Transport Link speed. Setting to [Auto], the sys-
tem will detect the HT link speed automatically.
▶ Adjusted HT Link Frequency (MHz)
It shows the adjusted HT Link frequency. Read-only.
▶ Adjust PCI-E Frequency (MHz)
This field allows you to select the PCIE frequency (in MHz).
▶ 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 Voltage (V)/ CPU-NB Voltage (V)/ DRAM Voltage (V)/ NB Voltage (V)/ SB Volt-
age (V)/ HT Link 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.
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 over-
clocked processor to lock up.
