▶Current CH1/ CH2 tdrRdTRd/ tddRdTRd/ tsrRdTWr/ tdrRdTWr/ tddRdTWr/
tsrWrTRd/ tddWrTWr/ tsrRDTRd/ tsrWrTWr
These item show the advanced DRAM timings.
▶Channel 1/ Channel2 Advanced Memory Setting
Setting to [Auto] enables the advance memory timing automatically to be determined
by BIOS. Setting to [Manual] allows you to set the following advanced memory timings.
▶Memory Ratio
This item allows you to set the memory multiplier.
▶Adjusted DRAM Frequency (MHz)
It shows the adjusted DRAM frequency. Read-only.
▶QPI Ratio
This item allows you to set the QPI multiplier.
▶Adjusted QPI Frequency (MHz)
It shows the adjusted QPI frequency. Read-only.
▶ClockGen Tuner
Press to enter the sub-menu and the following screen appears.
▶CPU Amplitude Control/ PCI Express Amplitude Control
These items are used to select the CPU/ PCI Express clock amplitude.
▶Adjust PCI-E Frequency (MHz)
This field allows you to select the PCIE frequency (in MHz).
▶Auto Disable PCI Frequency
When set to [Enabled], the system will remove (turn off) clocks from empty PCI slot to
minimize the electromagnetic interference (EMI).
▶CPU Voltage(V)/ PCH 1.8V (V)/ DRAM Voltage (V)/ DDR_VREF_CA_A (V)/ / DDR_
VREF_CA_B (V)/ DDR_VREF_DA_A (V)/ / DDR_VREF_DA_B (V)/ PCH 1.05V (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.
