▶ tWTR
Minimum time interval between the end of write data burst and the start of a column-
read command. It allows I/O gating to overdrive sense amplifiers before read
command starts.
▶ tRFC
This setting determines the time RFC takes to read from and write to a memory
cell.
▶ Advanced Channel 1/ 2 Timing Configuration
Press <Enter> to enter the sub-menu. And you can set the advanced memory timing
for each channel.
▶ tRWTT/ tWRRD/ tWRWR/ tRDRD
These items is used to set the memory timings for memory channel 1/ 2.
▶ 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.
▶ 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
It shows the adjusted HT Link 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.
▶ Adjust PCI-E Frequency (MHz)
This field allows you to select the PCIe frequency (in MHz).
▶ DRAM Voltage/ SB Voltage/ NB Voltage/ CPU Voltage/ CPU-NB Voltage
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.
