`` 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. && Performance Enhance Allows the system to operate at three different performance levels. Normal 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 Quick and Expert allows the Channel Interleaving, Rank Interleaving, and memory timing settings below 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 1.50V. 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. && 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) && 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. Auto lets the BIOS automatically configure this setting. (Default: Auto) `` 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. `` Advanced Voltage Settings `` CPU Core Voltage Control This section provides CPU voltage control options. `` Chipset Voltage Control This section provides Chipset voltage control options. `` DRAM Voltage Control This section provides memory voltage control options. (Note) This item is present only when you install a memory module that supports this feature. - 21 -
