Performance Enhance Allows the system to operate at three different performance levels. Standard Lets the system operate at its basic performance level. Turbo Lets the system operate at its good performance level. (Default) Extreme Lets the system operate at its best performance level. DRAM Timing Selectable (SPD) Quick and Expert allows the Channel Interleaving, Rank Interleaving, Channel A Timing Settings, and Channel B Timing Settings items to be configurable. Options are: Auto (default), Quick, Expert. Profile DDR Voltage When using a non-XMP memory module or Extreme Memory Profile (X.M.P.) is set to Disabled, this item will display as 1.5V. 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. Profile VTT Voltage The value displayed here is dependent on the CPU being used. Channel Interleaving Enables or disables memory channel interleaving. Enabled allows the system to simultaneously access different channels of the memory to increase memory performance and stability. Auto lets the BIOS automatically configure this setting. (Default: Auto) (Note) This item is present only when you install a memory module that supports this feature. - 41 - BIOS Setup
