Anleitung Zusammenfassung
To flash the BIOS, do it with caution. Inadequate BIOS flashing may result in system malfunction. ••It is recommended that you not alter the default settings (unless you need to) to prevent system instability or other unexpected results. Inadequately altering the settings may result in system's failure to boot. If this occurs, try to clear the CMOS values and reset the board to default values. (Refer to the "Load Optimized Defaults" section in this chapter or introductions of the battery/clear CMOS jumper in Chapter 1 for how to clear the CMOS values.) 2-1 Startup Screen The following startup Logo screen will appear when the computer boots. (Sample BIOS Version: Fa1) Function Keys On the main menu of the BIOS Setup program, press arrow keys to move among the items and press to accept or enter a sub-menu. Or you can use your mouse to select the item you want. ••When the system is not stable as usual, select the Load Optimized Defaults item to set your system to its defaults. ••The BIOS Setup menus described in this chapter are for reference only and may differ by BIOS version. 2-2 M.I.T. This section provides information on the BIOS version, CPU base clock, CPU frequency, memory frequency, total memory size, CPU temperature, Vcore, and memory voltage. Whether the system will work stably with the overclock/overvoltage settings you made is dependent on your overall system configurations. Incorrectly doing overclock/overvoltage may result in damage to CPU, chipset, or memory and reduce the useful life of these components. This page is for advanced users only and we recommend you not to alter the default settings to prevent system instability or other unexpected results. (Inadequately altering the settings may result in system's failure to boot. If this occurs, clear the CMOS values and reset the board to default values.) ``M.I.T. Current Status This screen provides information on CPU/memory frequencies/parameters. ``Advanced Frequency Settings &&Performance Upgrade (Note) Provides you with five different overclocking configurations. Options are: 20% Upgrade, 40% Upgrade, 60% Upgrade, 80% Upgrade, 100% Upgrade. (Default: Auto) &&Processor Graphics Clock Allows you to set the onboard graphics clock. The adjustable range is from 400 MHz to 4000 MHz. (Default: Auto) &&CPU Upgrade (Note) Allows you to set the CPU frequency. Options may vary depending on the CPU being used. (Default: Auto) &&CPU Clock Ratio Allows you to alter the clock ratio for the installed CPU. The adjustable range is dependent on the CPU being installed. &&CPU Frequency Displays the current operating CPU frequency. ``Advanced CPU Core Features &&CPU Clock Ratio, CPU Frequency The settings above are synchronous to those under the same items on the Advanced Frequency Settings menu. &&K OC (Note) Allows for increased performance by using certain CPUs. (Default: Auto) &&CPU PLL Selection Allows you to set the CPU PLL. Auto lets the BIOS automatically configure this setting. (Default: Auto) &&Filter PLL Level Allows you to set the Filter PLL. Auto lets the BIOS automatically configure this setting. (Default: Auto) &&Uncore Ratio Allows you to set the CPU Uncore ratio. The adjustable range is dependent on the CPU being used. &&Uncore Frequency Displays the current CPU Uncore frequency. &&Intel(R) Turbo Boost Technology (Note) Allows you to determine whether to enable the Intel CPU Turbo Boost technology. Auto lets the BIOS automatically configure this setting. (Default: Auto) &&Turbo Ratio (1-Core Active~4-Core Active) (Note) Allows you to set the CPU Turbo ratios for different number of active cores. Auto sets the CPU Turbo ratios according to the CPU specifications. (Default: Auto) &&Turbo Power Limit (Watts) Allows you to set a power limit for CPU Turbo mode. When the CPU power consumption exceeds the specified power limit, the CPU will automatically reduce the core frequency in order to reduce the power. Auto sets the power limit according to the CPU specifications. (Default: Auto) &&Core Current Limit (Amps) Allows you to set a current limit for CPU Turbo mode. When the CPU current exceeds the specified current limit, the CPU will automatically reduce the core frequency in order to reduce the current. Auto sets the power limit according to the CPU specifications. (Default: Auto) &&No. of CPU Core Enabled (Note) Allows you to select the number of CPU cores to enable in an Intel® multi-core CPU (the number of CPU cores may vary by CPU). Auto lets the BIOS automatically configure this setting. (Default: Auto) &&Hyper-Threading Technology (Note) Allows you to determine whether to enable multi-threading technology when using an Intel® CPU that supports this function. This feature only works for operating systems that support multi-processor mode. Auto lets the BIOS automatically configure this setting. (Default: Auto) &&CPU Enhanced Halt (C1E) (Note) Enables or disables Intel® CPU Enhanced Halt (C1E) function, a CPU power-saving function in sy...
