`` Advanced Memory Settings && E xtreme 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. && 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) && 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 && DRAM Voltage Allows you to set the memory voltage. (Default: Auto) `` 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. (Note) This item is present only when you install a CPU and a memory module that support this feature. - 21 -
