Adjust CPU Ratio This item is used to adjust CPU clock multiplier (ratio). It is available only when the processor supports this function. Adjusted CPU Frequency (M Hz) This item shows the adjusted CPU frequency. Advance DRAM Configuration Press <Enter> to enter the sub-menu and the following screen appears. DRAM Timing Mode Selects whether DRAM timing is controlled by the SPD (Serial Presence Detect) EEPROM on the DRAM module. Setting to [Auto] enables DRAM timings and the following related items 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 items manually. Bank Interleaving This field selects 2-bank or 4-bank interleave for the installed SDRAM. Disable the function if 16MB SDRAM is installed. 1T/2T M emory Timing W hen the Memory Timings is set to [Manual], the field is adjustable. This field controls the SDRAM command rate. Selecting [1T] makes SDRAM signal controller to run at 1T (T=clock cycles) rate. Selecting [2T] makes SDRAM signal controller run at 2T rate. SoftWare M emory Hole In order to improve performance, certain space in memory can be reserved for ISA peripherals. This memory must be mapped into the memory space below 16MB. W hen this area is reserved, it cannot be cached. FSB/DRAM Ratio This setting controls the ratio of CPU FSB Clock & DRAM Frequency to enable the CPU FSB & DRAM to run at different frequency combinations (non-synchronous overclocking). Please note that the setting options vary according to the CPU FSB Clock preset. 3-20 BIOS Setup Adjusted DRAM Frequency (MHz) This item shows the adjusted DRAM frequency. HT Configuration Press <Enter> to enter the sub-menu and the following screen appears. SB to AM2 FreqAuto Selecting [Disabled] allows users to configure the frequency (from SB to CPU) and the following related items manually. SB to AM 2 Freq This field selects the frequency from SB to CPU. [. . . ] If you do not want to apply the adjustments, click the Cancel button to cancel.
