&& 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 Defficient Turbo (Note 1) Enables or disables the CPU power saving related settings. && Voltage Optimization (Note 1) Allows you to determine whether to enable voltage optimization to reduce power consumption. (Default: Auto) && RSR (Note 1) Allows you to determine whether to automatically lower the CPU turbo ratio if the CPU voltage/temperature is too high. (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) (Note 2) 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. (Note 1) This item is present only when you install a CPU that supports this feature. For more information about Intel® CPUs' unique features, please visit Intel's website. (Note 2) This item is present only when you install a CPU and a memory module that support this feature. - 49 - BIOS Setup

&
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 Defficient Turbo
(Note 1)
Enables or disables the CPU power saving related settings.
&

(Note 1)
Allows you to determine whether to enable voltage optimization to reduce power consumption. (Default:
Auto)
&
RSR
(Note 1)
Allows you to determine whether to automatically lower the CPU turbo ratio if the CPU voltage/temperature
is too high. (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)
