Precharge Time Options are: Auto (default), 2T, 3T. Row Cycle Time Options are: Auto (default), 11T~26T. RAS to RAS Delay Options are: Auto (default), 2T~5T. HT Link Frequency Allows you to manually set the frequency for the HT Link between the CPU and chipset. Auto BIOS will automatically adjust the HT Link Frequency. (Default) 200 MHz~2.6 GHz Sets HT Link Frequency to 200 MHz~2.6 GHz. VGA Core Clock control Enables or disables the control of VGA Core clock. VGA Core Clock (Mhz) Allows you to manually set the VGA Core clock. The adjustable range is from 200 MHz to 2000 MHz. This item is configurable only if the VGA Core Clock control option is enabled. EPP Mode (Note 1) Enables or disables EPP mode when EPP memory is installed. Auto enables EPP mode for EPP memory to enhance performance. (Default: Disabled) EPP Voltage Control (Note 1) Allows you to configure EPP memory voltage. Normal Lets BIOS optimize memory voltage settings. (Default) By EPP Sets memory voltage according to the SPD data on the EPP memory. CPU Clock Ratio Allows you to alter the clock ratio for the installed CPU. The adjustable range is dependent on the CPU being used. CPU NorthBridge Freq. (Note 2) Allows you to alter the North Bridge controller frequency for the installed CPU. The adjustable range is dependent on the CPU being used. CPU Host Clock Control Enables or disables the control of CPU host clock. Auto (default) allows BIOS to automatically adjust the CPU host frequency. Manual allows the CPU Frequency (Mhz) item below to be configurable. Note: If your system fails to boot after overclocking, please wait for 20 seconds to allow for automated system reboot, or clear the CMOS values to reset the board to default values. CPU Frequency (MHz) Allows you to manually set the CPU host frequency. Important It is highly recommended that the CPU frequency be set in accordance with the CPU specifications. PCIE Clock (MHz) Allows you to manually set the PCIe clock frequency. The adjustable range is from 100 MHz to 200 MHz. Auto sets the PCIe clock frequency to standard 100 MHz. (Default: Auto) (Note 1) This item appears only if you install a memory module that supports this feature. (Note 2) This item is present only if you install a CPU that supports this feature. - 41 - BIOS Setup
