▍ BIOS Setup ▶ 1T/2T Memory Timing This item controls the SDRAM command rate. Select [1T] makes SDRAM signal controller to run at 1T (T=clock cycles) rate. Selecting [2T] makes SDRAM signal controller run at 2T rate. ▶ DCT Unganged Mode This feature is used to Integrate two 64-bit DCTs into a 128-bit interface. ▶ Bank Interleaving Bank Interleaving is an important parameter for improving overclocking capability of memory. It allows system to access multiple banks simultaneously. ▶ Power Down Enable This is a memory power-saving technology. When the system does not access memory over a period of time, it will automatically reduce the memory power supply. ▶ 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 to enter the sub-menu and the following screen appears. ▶ 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 system 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 DIMMs/ PCI slots to minimize the electromagnetic interference (EMI). 3-22

BIOS Setup
▍
1T/2T Memory T±m±ng
Th±s ±tem controls the SDRAM command rate. Select [1T] makes SDRAM s±gnal
controller to run at 1T (T=clock cycles) rate. Select±ng [2T] makes SDRAM s±gnal
controller run at 2T rate.
DCT Unganged Mode
Th±s feature ±s used to Integrate two 64-b±t DCTs ±nto a 128-b±t ±nterface.
Bank Interleav±ng
Bank Interleav±ng ±s an ±mportant parameter for ±mprov±ng overclock±ng capab±l±ty of
memory. It allows system to access mult±ple banks s±multaneously.
Power Down Enable
Th±s ±s a memory power-sav±ng technology. When the system does not access mem-
ory over a per±od of t±me, ±t w±ll automat±cally reduce the memory power supply.
MemClk Tr±state C3/ATLVID
Th±s sett±ng allows you to enable/d±sable the MemClk Tr±stat±ng dur±ng C3 and
ATLVID.
FSB/DRAM Rat±o
Th±s ±tem allows you to select the rat±o of FSB/ DRAM.
Adjusted DRAM Frequency (MHz)
It shows the adjusted Memory frequency. Read-only.
HT L±nk Control
Press <Enter> to enter the sub-menu and the follow±ng screen appears.
HT Incom±ng/ Outgo±ng L±nk W±dth
These ±tems allow you to set the Hyper-Transport L±nk w±dth. Sett±ng to [Auto], the
system w±ll detect the HT l±nk w±dth automat±cally.
HT L±nk Speed
Th±s ±tem allows you to set the Hyper-Transport L±nk speed. Sett±ng to [Auto], the sys-
tem w±ll detect the HT l±nk speed automat±cally.
Adjusted HT L±nk Frequency (MHz)
It shows the adjusted HT L±nk frequency. Read-only.
Adjust PCI-E Frequency (MHz)
Th±s field allows you to select the PCIE frequency (±n MHz).
Auto D±sable DRAM/PCI Frequency
When set to [Enabled], the system w±ll remove (turn off) clocks from empty DRAM
DIMMs/ PCI slots to m±n±m±ze the electromagnet±c ±nterference (EMI).
