Enabled will allow the BCLK 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. (Default: Disabled) BCLK Frequency (Mhz) Allows you to manually set the CPU base clock. The adjustable range is from 100 MHz to 1200 MHz. This item is configurable only if the Base Clock(BCLK) Control option is enabled. 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) 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 1 1% 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. GA-EX58-UD5P/UD5 Motherboard - 48 -
