English 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) C.I.A.2 CPU Intelligent Accelerator 2 (C.I.A.2) is designed to automatically adjust CPU computing power to maximize system performance. C.I.A.2 allows your system bus to be changed dynamically based on CPU loading through the use of 5 preset states. Note: System stability varies, depending on your system hardware components. Disabled Disables the use of C.I.A.2. (Default) Cruise Increases CPU frequency by 5% or 7% depending on CPU loading. Sports Increases CPU frequency by 7% or 9% depending on CPU loading. Racing Increases CPU frequency by 9% or 11% depending on CPU loading. Turbo Increases CPU frequency by 15% or 17% depending on CPU loading. Full Thrust Increases CPU frequency by 17% or 19% depending on CPU loading. Warning: Before using C.I.A.2, please first verify the overclocking capability of your CPU. As stability is highly dependent on system components, when system instability occurs after overclocking, lower the overclocking ratio. System Memory Multiplier (SPD) 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. DDR2 OverVoltage Control Allows you to to set memory voltage. Normal Supplies the memory voltage as required. (Default) +0.1V ~ +0.7V Increases memory voltage by 0.1V to 0.7V at 0.1V increment. Note: Increasing memory voltage may result in damage to the memory. PCI-E OverVoltage Control Allows you to to set PCIe voltage. Normal Supplies the PCIe bus voltage as required. (Default) +0.1V ~ +0.3V Increases PCIe bus voltage by 0.1V to 0.3V at 0.1V increment. 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.
