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. Extreme Memory Profile (X.M.P.) (Note) Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance when enabled. Disabled Disables this function. (Default) Profile1 Uses Profile 1 settings. Profile2 (Note) Uses Profile 2 settings. System Memory Multiplier (SPD) Allows you to set the system memory multiplier. 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 BCLK Frequency(Mhz) and System Memory Multiplier settings. 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. >>>>> Advanced Clock Control CPU Clock Drive Allows you to adjust the amplitude of the CPU and the Chipset clock. Options are: 700mV, 800mV (default), 900mV, 1000mV. PCI Express Clock Drive Allows you to adjust the amplitude of the PCI Express and Chipset clock. Options are: 700mV, 800mV, 900mV (default), 1000mV. (Note) This item appears only if you install a memory module that supports this feature. BIOS Setup - 44 -
