••@BIOS is a Windows-based utility that searches and downloads the latest version of BIOS from the Internet and updates the BIOS. ••Because BIOS flashing is potentially risky, if you do not encounter problems using the current version of BIOS, it is recommended that you not flash the BIOS. 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: E13) 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 &&BCLK/PCIe Clock Control Allows you to manually set the CPU base clock and PCIe bus frequency in 1 MHz increments. (Default: Auto) Important: It is highly recommended that the CPU frequency be set in accordance with the CPU specifications. &&Processor Graphics Clock Allows you to set the onboard graphics clock. The adjustable range is from 300 MHz to 2000 MHz. &&CPU NB Clock Divisor (Note) Allows you to set the CPU North Bridge frequency divisor. &&CPU NB Clock Frequency Displays the current operating CPU North Bridge frequency. &&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. (Note) This item is present only when you install a CPU that supports this feature. ``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. &&Core Performance Boost (Note 1) Allows you to determine whether to enable the Core Performance Boost (CPB) technology, a CPU performance-boost technology. (Default: Auto) &&Core Performance Boost Ratio (Note 1) Allows you alter the ratio for the CPB. The adjustable range is dependent on the CPU being installed. (Default: Auto) &&C6 Mode Allows you to determine whether to let the CPU enter C6 mode in system halt state. When enabled, the CPU core frequency will be reduced during system halt state to decrease power consumption. The C6 state is a more enhanced power-saving state than C1. (Default: Disabled) &&AMD Cool&Quiet function Enabled Lets the AMD Cool'n'Quiet driver dynamically adjust the CPU clock and VID to reduce heat output from your computer and its power consumption. (Default) Disabled Disables this function. &&SVM Mode Virtualization enhanced by Virtualization Technology will allow a platform to run multiple operating systems and applications in independent partitions. With virtualization, one computer system can function as multiple virtual systems. (Default: Enabled) &&C-state Pmin Allows you to determine whether to let the CPU enter C1 mode in system halt state. When enabled, the CPU core frequency and voltage will be reduced during system halt state to decrease power con-sumption. Auto lets the BIOS automatically configure this setting. (Default: Auto) &&Extreme Memory Profile (X.M.P.) (Note 2) 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 2) Uses Profile 2 settings. &&System Memory Multiplier Allows you to set the system memory multiplier. Auto...
