&& Core C6 State (Note 1) Allows you to determine whether to let the CPU enter C6 mode in system halt state. When enabled, the CPU core frequency will be reduced during system halt state to decrease power consumption. The C6 state is a more enhanced power-saving state than C1. (Default: Enabled) && HPC Mode (Note 1) Allows you to determine whether to enable High Performance Computing (HPC) mode for the CPU. Enabled prevents the CPU frequency from being lowered during system halt state. (Default: Disabled) && APM (AMD Application Power Management) (Note 1) Enabled Dynamically monitors the power consumption of the CPU cores and automatically optimizes the CPU to its best performance level. (Default) Disabled Disables this function. && Extreme Memory Profile (X.M.P.) (Note 2) Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance when enabled. Disabled Disables this function. (Default) Profile1 Uses Profile 1 settings. Profile2 (Note 2) Uses Profile 2 settings. && System Memory Multiplier Allows you to set the system memory multiplier. Auto sets memory multiplier according to memory SPD data. (Default: Auto) && Memory Frequency (MHz) This value is automatically adjusted according to the BCLK Clock Control and System Memory Multiplier settings. `` Advanced Memory Settings && Extreme Memory Profile (X.M.P.) (Note2), System Memory Multiplier, Memory Frequency(MHz) The settings above are synchronous to those under the same items on the Advanced Frequency Settings menu. && DRAM Timing Selectable Quick and Expert allows the 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, the value is displayed according to your memory specification. When Extreme Memory Profile (X.M.P.) is set to Profile1 or Profile2, the value is displayed according to 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) (Note 1) This item is present only when you install a CPU that supports this feature. (Note 2) This item is present only when you install a memory module that supports this feature. - 23 -
