&& Ring to Core offset (Down Bin) Allows you to determine whether to disable the CPU Ring ratio auto-down function. Auto lets the BIOS automatically configure this setting. (Default: Auto) && CPU EIST Function (Note 1) Enables or disables Enhanced Intel® Speed Step Technology (EIST). Depending on CPU loading, Intel® EIST technology can dynamically and effectively lower the CPU voltage and core frequency to decrease average power consumption and heat production. Auto lets the BIOS automatically configure this setting. (Default: Auto) && Race To Halt (RTH) (Note 1)/Energy Efficient Turbo (Note 1) Enables or disables the CPU power saving related settings. && Voltage Optimization Allows you to determine whether to enable voltage optimization to reduce power consumption. (Default: Auto) && Hardware Prefetcher Allows you to determine whether to enable hardware prefetcher to prefetch data and instructions from the memory into the cache. (Default: Auto) && Adjacent Cache Line Prefetch Allows you to determine whether to enable the adjacent cache line prefetch mechanism that lets the processor retrieve the requested cache line as well as the subsequent cache line. (Default: Auto) && 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 Ref Clock Allows you to manually adjust the memory reference clock. (Default: Auto) && Memory Odd Ratio (100/133 or 200/266) Enabled allows Qclk to run in odd frequency. (Default: Auto) && Memory Frequency (MHz) The first memory frequency value is the normal operating frequency of the memory being used; the second is the memory frequency that is automatically adjusted according to the System Memory Multiplier settings. `` 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. && Case Open Displays the detection status of the chassis intrusion detection device attached to the motherboard CI header. If the system chassis cover is removed, this field will show "Yes", otherwise it will show "No". To clear the chassis intrusion status record, set Reset Case Open Status to Enabled, save the settings to the CMOS, and then restart your system.
