CPU EIST Function
(Note)
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)
&
Voltage Optimization
Allows you to determine whether to enable voltage optimization to reduce power consumption. (Default:
Disabled)
&
RSR
Allows you to determine whether to automatically lower the CPU turbo ratio if the CPU voltage/temperature
is too high. (Default: Enabled)
&
Hardware Prefetcher
Allows you to determine whether to enable hardware prefetcher to prefetch data and instructions from the
memory into the cache. (Default: Enabled)
&
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: Enabled)
&
Extreme Memory Profile (X.M.P.)
(Note)
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)
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.
`
Advanced Memory Settings
&
Extreme Memory Profile (X.M.P.)
(Note )
, System Memory Multiplier, Memory Ref Clock,
Memory Odd Ratio(100/133 or 200/266), Memory Frequency(Mhz)
The settings above are synchronous to those under the same items on the
Advanced Frequency Settings
menu.
&
Memory Boot Mode
(Note)
Provides memory detection and training methods.
Auto
Lets the BIOS automatically configure this setting. (Default)
Normal
The BIOS automatically performs memory training. Please note that if the system
becomes unstable or unbootable, try to clear the CMOS values and reset the board to
default values. (Refer to the introductions of the battery/clear CMOS jumper in Chapter
1 for how to clear the CMOS values.)
(Note) This item is present only when you install a CPU and a memory module that support this feature.
