BIOS Setup
- 46 -
& EnergyEfcientTurbo
Enables or disables the CPU power saving related settings. (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)
& CPU PLL Trim /MC PLL Trim /PLL Trim Threshold
 Allowsyoutone-tuneCPU/MCPLLrelatedsettings.(Default:Auto)
& Enhanced Multi-Core Performance
Determines whether to allow the CPU to run at Turbo 1C speed. AutoletstheBIOSautomaticallycongure
this setting. (Default: Auto)
d Intel(R) Turbo Boost Technology
Allows you to determine whether to enable the Intel
®
CPU Turbo Boost technology. Auto lets the BIOS
automaticallycongurethissetting.(Default:Auto)
& Turbo Ratio
Allows you to set the CPU Turbo ratios for different number of active cores. Auto sets the CPU Turbo ratios
accordingtotheCPUspecications.ThisitemiscongurableonlywhenIntel(R) Turbo Boost Technology
is set to Enabled. (Default: Auto)
d Turbo Per Core Limit Control
Allows you to control each CPU core limit separately. (Default: Auto)
d Active Cores Control
Allows you to select the number of CPU cores to enable in an Intel
®
multi-core CPU (the number of CPU
cores may vary by CPU). AutoletstheBIOSautomaticallycongurethissetting.(Default:Auto)
d C-States Control
& CPU Enhanced Halt (C1E)
Enables or disables Intel
®
CPU Enhanced Halt (C1E) function, a CPU power-saving function in system
halt state. When enabled, the CPU core frequency and voltage will be reduced during system halt state
to decrease power consumption. Autolets the BIOS automatically congurethis setting. Thisitem is
congurableonlywhenC-States Control is enabled. (Default: Auto)
& C6/C7 State Support
Allows you to determine whether to let the CPU enter C6/C7 mode in system halt state. When enabled, the
CPU core frequency and voltage will be reduced during system halt state to decrease power consumption.
The C6/C7 state is a more enhanced power-saving state than C3. AutoletstheBIOSautomaticallycongure
thissetting.ThisitemiscongurableonlywhenC-States Control is enabled. (Default: Auto)
& Package C State limit
Allows you to specify the C-state limit for the processor. AutoletstheBIOSautomaticallycongurethis
setting.ThisitemiscongurableonlywhenC-States Control is enabled. (Default: Auto)
d Turbo Power Limits
Allows you to set a power limit for CPU Turbo mode. When the CPU power consumption exceeds the
speciedpowerlimit,theCPUwillautomaticallyreducethecorefrequencyinordertoreducethepower.
AutosetsthepowerlimitaccordingtotheCPUspecications.(Default:Auto)
