Setting to [Auto] enables DRAM timings and the following “Advance DRAM Configuration” sub-menu to be determined by BIOS based on the configurations on the SPD. Selecting [Manual] allows users to configure the DRAM timings and the following related “Advance DRAM Configuration” sub-menu manually. MS-7522 Mainboard ▶ CH1/ CH2/ CH3 tRRD Specifies the active-to-active delay of different banks. ▶ CH1/ CH2/ CH3 tRTP Time interval between a read and a precharge command. ▶ CH1/ CH2/ CH3 tFAW This item is used to set the tFAW timing. ▶ Current CH1/ CH2/ CH3 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. ▶ Uncore Ratio This item allows you to set the uncore multiplier. ▶ Adjusted Uncore Frequency (MHz) It shows the adjusted uncore frequency. Read-only. ▶ QPI Configuration Press <Enter> to enter the sub-menu. ▶ QPI Links Speed This item allows you to select the QPI links speed type. ▶ QPI Frequency This item allows you to select the QPI frequency. ▶ ClockGen Tuner Press <Enter> to enter the sub-menu. ▶ CPU Amplitude Control/ PCI Express Amplitude Control These items are used to select the CPU/ PCI Express clock amplitude. ▶ CPU CLK Skew/ MCH CLK Skew These items are used to select the CPU/ MCH chipset clock skew. They can help CPU to reach the higher overclocking performance. ▶ Adjust PCI Frequency (MHz) This field allows you to select the PCI frequency (in MHz). ▶ Adjust PCI-E Frequency (MHz) This field allows you to select the PCIE frequency (in MHz). En-36 ▶ Auto Disable PCI/PCI-E Frequency When set to [Enabled], the system will remove (turn off) clocks from empty PCI and PCI-E slots to minimize the electromagnetic interference (EMI). ▶ 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 overclocked processor to lock up. En-37 English ▶ CPU Voltage (V)/ CPU PLL Voltage (V)/ QPI Voltage (V)/ DRAM Voltage (V)/ DDR_ VREF_CA_A (V)/ DDR_VREF_CA_B (V)/ DDR_VREF_CA_C (V)/ DDR_VREF_DQ_A (V)/ DDR_VREF_DQ_B (V)/ DDR_VREF_DQ_C (V)/ IOH Voltage (V)/ ICH Voltage (V) These items are used to adjust the voltage of CPU, Memory and chipset. MS-7522 Mainboard Important Failed Overclocking Resolution This mainboard supports overclocking greatly. However, please make sure your peripherals and components are bearable for some special settings. Any operation that exceeds product specification is not recommended. Any risk or damge resulting from improper operation will not be under our product warranty. Two ways to save your system from failed overclocking...
• Reboot Press the Power button to reboot the system three times. Please note that, to avoid electric current to affect other devices or components, we suggest an interval of more than 10 seconds among the reboot actions. At the fourth reboot, BIOS will determine that the previous overclocking is failed and restore the default settings automatically. Please press any key to boot the system normally when the following message appears on screen. Warning !!! The previous overclocking had failed, and system will restore its defaults setting, Press any key to continue.......
