Robust Graphics Booster Robust Graphics Booster (R.G.B.) helps to enhance the performance of the graphics chip and memory. Auto allows the BIOS to automatically set the R.G.B. mode based on system configurations. Options are: Auto (default), Fast, Turbo. CPU Clock Ratio (Note) Allows you to alter the clock ratio for the installed CPU. The item is present only if a CPU with unlocked clock ratio is installed. Fine CPU Clock Ratio (Note) Allows you to increases clock ratio by 0.5 for the installed CPU. The item is present only if a CPU with unlocked clock ratio is installed. CPU Frequency Displays the current operating CPU frequency. ******** Clock Chip Control Standard Clock Control CPU Host Clock Control Enables or disables the control of CPU host clock. Enabled will allow the CPU Host Frequency 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. (Default: Disabled) CPU Host Frequency (Mhz) Allows you to manually set the CPU host frequency. The adjustable range is from 100 MHz to 1200 MHz. This item is configurable only if the CPU Host Clock Control option is enabled. For an 800 MHz FSB CPU, set this item to 200 MHz. For a 1066 MHz FSB CPU, set this item to 266 MHz. For a 1333 MHz FSB CPU, set this item to 333 MHz. Important: It is highly recommended that the CPU frequency be set in accordance with the CPU specifications. PCI Express Frequency (Mhz) Allows you to manually set the PCIe clock frequency. The adjustable range is from 90 MHz to 150 MHz. Auto sets the PCIe clock frequency to standard 100 MHz. (Default: Auto) ******** DRAM Performance Control ******** Performance Enhance Allows the system to operate at three different performance levels. Standard Lets the system operate at its basic performance level. (Default) Turbo Lets the system operate at its good performance level. Extreme Lets the system operate at its best performance level. (Note) This item appears only if you install a CPU that supports this feature. BIOS Setup - 36 -
