& 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congure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congurethissetting.
(Default: Auto)
& RaceToHalt(RTH)
(Note1)
/EnergyEfcient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Prole(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)

Prole2
(Note 2)
 UsesProle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rst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eld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eld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.
