English CPU Host Frequency (Mhz) Allows you to manually set the CPU host frequency. 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) System Memory Multiplier Allows you to set the system memory multiplier. Options are dependent on CPU FSB. Auto sets memory multiplier according to memory SPD data. (Default: Auto) Memory Frequency (Mhz) The first memory frequency value is the normal operating frequency of the memory being used; the second is the memory frequency that is automatically adjusted according to the CPU Host Frequency (Mhz) and System Memory Multiplier settings. High Speed DRAM DLL Settings Provides two different memory timing configurations. If your system becomes unstable after you overclock the DDR2 memory, select Option 1 or Option 2 to help make your system more stable. Option 1 Memory Timing Configuration 1. (Default) Option 2 Memory Timing Configuration 2. System Voltage Control Determines whether to manually set the system voltages. Auto lets BIOS automatically set the system voltages as required. Manual allows all voltage control items below to be configurable. (Default: Manual) DDR2 OverVoltage Control Allows you to to set memory voltage. Normal Supplies the memory voltage as required. (Default) +0.1V ~ +0.4V Increases memory voltage by 0.1V to 0.4V at 0.1V increment. Note: Increasing memory voltage may result in damage to the memory. FSB OverVoltage Control Allows you to set the Front Side Bus voltage. Normal Supplies the FSB voltage as required. (Default) +0.1V ~ +0.3V Increases FSB voltage by 0.1V to 0.3V at 0.1V increment.
