[. . . ] Profile2 (Note) Uses Profile 2 settings.  Allows you to set the system memory multiplier. Auto sets memory multiplier according to memory SPD data. (Default: Auto) This value is automatically adjusted according to the BCLK/PCIe Clock Control and System Memory Multiplier settings. && System Memory Multiplier && Memory Frequency (MHz) `` Advanced Memory Settings && Extreme Memory Profile (X. M. P. ) (Note), System Memory Multiplier, Memory Frequency(MHz) The settings above are synchronous to those under the same items on the Advanced Frequency Settings menu. Quick and Expert allows the memory timing settings below to be configurable. Options are: Auto (default), Quick, Expert. When using a non-XMP memory module or Extreme Memory Profile (X. M. P. ) is set to Disabled, this item will display as 1. 50V. When Extreme Memory Profile (X. M. P. ) is set to Profile1 or Profile2, this item will display the value based on the SPD data on the XMP memory. && DRAM Timing Selectable && Profile DDR Voltage (Note) This item is present only when you install a memory module that supports this feature. - 29 - && Profile VTT Voltage The value displayed here is dependent on the CPU being used. && Rank Interleaving Enables or disables memory rank interleaving. Enabled allows the system to simultaneously access different ranks of the memory to increase memory performance and stability. (Default: Enabled) Enables or disables memory channel interleaving. Enabled allows the system to simultaneously access different channels of the memory to increase memory performance and stability. (Default: Enabled) && Channel Interleaving `` Channel A/B Timing Settings This sub-menu provides memory timing settings for each channel of memory. The respective timing setting screens are configurable only when DRAM Timing Selectable is set to Quick or Expert. Note: Your system may become unstable or fail to boot after you make changes on the memory timings. If this occurs, please reset the board to default values by loading optimized defaults or clearing the CMOS values. - 30 - `` Advanced Voltage Settings This sub-menu allows you to set CPU, Chipset, and memory voltages. `` PC Health Status && Reset Case Open Status Disabled Keeps or clears the record of previous chassis intrusion status. (Default)  Enabled   Clears the record of previous chassis intrusion status and the Case Open field will show "No" at next boot. - 31 - && Case Open Displays the detection status of the chassis intrusion detection device attached to the motherboard CI header. If the system chassis cover is removed, this field will show "Yes", otherwise it will show "No". To clear the chassis intrusion status record, set Reset Case Open Status to Enabled, save the settings to the CMOS, and then restart your system. Displays the current system voltages. && CPU Vcore/Dram Voltage/+3. 3V/+5V/+12V && CPU/System Temperature && CPU/System Fan Speed Displays current CPU/system temperature. Displays current CPU/system fan speeds. && CPU Warning Temperature Sets the warning threshold for CPU temperature. When CPU temperature exceeds the threshold, BIOS will emit warning sound. [. . . ] Follow the on-screen instructions to install the driver that suits your operating system. When completed, proceed with the Windows XP installation. (The following instructions use Windows 7 as the example operating system. ) Boot from the Windows 7 setup disk and perform standard OS installation steps.
