Any changes made to this setting may cause a stability issue, so changing the DDR voltage for long-term purpose is NOT recommended. ► Adjust NB Voltage (V) NorthBridge voltage is adjustable in the field, allowing you to increase the performance of your NorthBridge when overclocking, but stability may be affected. - Important The settings shown in different color in CPU Voltage, DDR Voltage and NB Voltage help to verify if your setting is proper for your system. Gray: Default setting. White: Safe setting. Yellow:High performance setting. Red: Not recommended setting and the system may be unstable. Changing CPU Voltage, DDR Voltage and NB Voltage may result in the instability of the system; therefore, it is NOT recommended to change the default setting for long-term usage. ► Spread Spectrum When the motherboard's clock generator pulses, the extreme values (spikes) of the pulses creates EMI (Electromagnetic Interference). The Spread Spectrum function reduces the EMI generated by modulating the pulses so that the spikes of the pulses are reduced to flatter curves. If you do not have any EMI problem, leave the setting at [Disabled] for optimal system stability and performance. But if you are plagued by EMI, select the desired range for EMI reduction. Remember to disable Spread Spectrum function if you are overclocking, because even a slight jitter can introduce a temporary boost in clock speed which may just cause your overclocked processor to lock up. ► Adjust CPU FSB Frequency This item allows you to select the CPU Front Side Bus clock frequency (in MHz) and overclock the processor by adjusting the FSB clock to a higher frequency. ► Adjust PCI Express Frequency This item allows you to select the PCI Express frequency (in MHz). ► Adjust PCI Frequency This item allows you to select the PCI frequency (in MHz). In default this value will change automatically in accordance with the setting of Adjust CPU FSB Frequency. However, you may adjust the desired fixed PCI frequency you like by using the <+> & <-> key. ► Auto Disable PCI Clock This item is used to auto disable the PCI slots. When set to [Enabled], the system will remove (turn off) clocks from empty PCI slots to minimize the electromagnetic interference (EMI). Load Optimized Defaults The two options on the main menu allow users to restore all of the BIOS settings to the default Fail-Safe or Optimized values. The Optimized Defaults are the default values set by the mainboard manufacturer specifically for optimal performance of the mainboard. The Fail-Safe Defaults are the default values set by the BIOS vendor for stable system performance. When you select Load Fail-Safe Defaults, a message as below appears: Load Fail -Safe Defaults (Y/№? N Pressing Y loads the BIOS default values for the most stable, minimal system performance. When you select Load Optimized Defaults, a message as below appears: Load Optimized Defaul ts CV/Н)? H Pressing Y loads the default factory settings for optimal system performance. Щ BIOS Setting Password When you select this function, a message as below will appear on the screen: Enter Password: Type the password, up to 6 characters in length, and press <Enter>. The password typed now will replace any previously set password from CMOS memory. You will be prompted to confirm the password. Retype the password and press <Enter>. You may also press <Esc> to abort the selection and not enter a password. To clear a set password, just press <Enter> when you are prompted to enter the password. A message will show up confirming the password will be disabled. Once the password is disabled, the system will boot and you can enter Setup without entering any password. When a password has been set, you will be prompted to enter it every time you try to enter Setup. This prevents an unauthorized person from changing any part of your system configuration.
