MS-7309 1T/2T Memory Timing When the DRAM Timing Mode is set to [Manual], the field is adjustable. This field controls the command rate. Selecting [1T] makes DRAM signal controller to run at 1 clock cycle rate. Selecting [2T] makes DRAM signal controller run at 2 clock cycles rate. Bank Interleaving Bank Interleaving is an important parameter for improving overclocking capability of memory. It allows system to access multiple banks simultaneously. FSB/DRAM Ratio This item will allow you to adjust the ratio of FSB to memory. Adjusted DRAM Frequency (MHz) It shows the adjusted memory frequency. Read-only. Adjust PCI-E Frequency (MHz) This item allows you to adjust the PCI-E frequency. HT Link Speed Auto Setting to [Enabled], the system will detect the HT link speed automatically. HT Link Speed This item allows you to set the Hyper-Transport Link speed. HT Link Width This item allows you to set the Hyper-Transport Link width. CPU VDD Voltage (V)/ Adjust CPU Voltage Offset/ DRAM Voltage (V)/ NB Voltage (V)/ HT Link Voltage (V) These items are used to adjust the voltage of CPU, Memory and chipset. CPU Spread Spectrum This setting is used to enable or disable the CPU Spread Spectrum feature. 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. 25
