BIOS Setup
- 44 -
& Core Current Limit (Amps)
Allows you to set a current limit for CPU Turbo mode. When the CPU current exceeds the specied current
limit, the CPU will automatically reduce the core frequency in order to reduce the current. Auto sets the
power limit according to the CPU specications. (Default: Auto)
& CPU Core Enabled
(Note 1)
Allows you to determine whether to enable all CPU cores. Auto lets the BIOS automatically congure this
setting. (Default: Auto)
& Hyper-Threading Technology
(Note 1)
Allows you to determine whether to enable multi-threading technology when using an Intel
®
CPU that
supports this function. This feature only works for operating systems that support multi-processor mode.
Auto lets the BIOS automatically congure this setting. (Default: Auto)
& CPU Enhanced Halt (C1E)
(Note 1)
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. (Default: Auto)
& C3/C6 State Support
(Note 1)
Allows you to determine whether to let the CPU enter C3/C6 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 C3/C6 state is a more enhanced power-saving state than C1. Auto lets the BIOS automatically congure
this setting. (Default: Auto)
& CPU Thermal Monitor
(Note 1)
Enables or disables Intel
®
Thermal Monitor function, a CPU overheating protection function. When enabled,
the CPU core frequency and voltage will be reduced when the CPU is overheated. 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)
& 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le1 Uses Prole 1 settings.
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 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.
