[. . . ] 6th level of overclocking, increasing the frequency by 15%. Important Even though the Dynamic Overclocking Technology is more stable than manual overclocking, basically, it is still risky. We suggest user to make sure that your CPU can afford to overclocking regularly first. If you find the PC appears to be unstable or reboot incidentally, it's better to disable the Dynamic Overclocking or to lower the level of overclocking options. By the way, if you need to conduct overclocking manually, you also need to disable the Dynamic OverClocking first. AMD Cool'n'Quiet The Cool'n' Quiet technology can effectively and dynamically lower CPU speed and power consumption. Important To ensure that Cool'n'Quiet function is activated and will be working properly, it is required to double confirm that: 1. Under Cell M enu, find AM D Cool'n'Q uiet, and s et this item to "Enable. " 2. Enter Windows , and select [Start]-> [Settings]->[Control Pannel]->[Power Options]. Enter Power Options Properties tag, and select Minimal Power Management under Power schemes. 3-19 M S-7375 M ainboard Adjust CPU FSB Frequency (M Hz) This item allows you to select the CPU Front Side Bus clock frequency (in MHz). Adjust CPU Ratio This item is used to adjust CPU clock multiplier (ratio). 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 Interleave This field selects 2-bank or 4-bank interleave for the installed SDRAM. 1T/2T M emory Timing W hen the Memory Timings is set to [Manual], the field is adjustable. Selecting [1T] makes SDRAM signal controller to run at 1T (T=clock cycles) rate. SoftWare M emory Hole In order to improve performance, certain space in memory can be reserved for ISA peripherals. DCT Unganged Mode (For AM 2+ CPU only) This mainboard supports dual-channel DRAM mode. W hen this is enabled, you can set different DRAM timing for these two channels. This item will appear when you install the CPU which supports unganged mode. 3-20 BIOS Setup SLI-Ready Memory Setting the item to [Auto] upgrades the memory module performance automatically when you install a pair of EPP (Enhanced Performance Profiles)-enabled memory modules. 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. [. . . ] That is to say, the Efficiency becomes higher when CPU has more loading. D-6 Dual Core Center Clock In the Clock sub-menu, you can see clock status (including FSB/ CPU clock of mainboard and GPU/ memory clock of graphics card) of your system. There will be several items for you to select for overclocking after you click button. You can click the plus sign button to increase the clock, or click the minus sign button to decrease the clock. If you do not want to apply the adjustments, click the Cancel button to cancel. [. . . ]
