Processor Idle
State
Performance
• High
Performance
• Low Power
High Performance forces the operating system to use
the Maximum Multiplier at all times.
Low Power allows the operating system to adjust the
multiplier down.
Processor Power
Efficiency Policy
Power
• High
Performance
• Balanced
• Low Power
Configures processor bias for power efficiency vs.
performance.
High Performance: Set MSR 1B0h Bits 3:0 to 0h
Balanced: Set MSR 1B0h Bits 3:0 to 5h
Low Power: Set MSR 1B0h Bits 3:0 to 7h

• Offset Only
• Interpolated +
Offset
• Static + Offset
Offset Only:
hides Voltage Target question,
sets Voltage Target Mode (Bit 20) to 0 (Adaptive),
sets Voltage Target (Bits 19:8) to 0
Interpolated + Offset:
displays Voltage Target question,
sets Voltage Target Mode (Bit 20) to 0 (Adaptive)
Static + Offset:
displays Voltage Target question,
sets Voltage Target Mode (Bit 20) to 1 (Static)

Numeric
Primarily used for overclocking.

Numeric
Primarily used for overclocking.
Processor
Signature
Main
Information
only
Displays the 32-bit processor signature in hexadecimal;
copied from EAX register output from the CPUID
instruction when EAX is set to 1.
Processor
Temperature
Cooling
Information
only
Displays the current processor temperature.
Processor Type
Main
Information
only
Displays the processor brand string obtained from the
CPUID instruction.
Processor Uncore
Frequency
Performance
Information
only
Displays the process uncore frequency.
Processor VR
Efficiency
Management
Performance
Checkbox
When disabled, processor power usage and heat will
increase in exchange for improved power delivery
control. This may be useful at higher processor base
clock frequencies.
Processor VR
Faults
Performance
Checkbox
When disabled, processor over-voltage and over-current
protection is disabled. This may be useful at very high
frequencies, but significantly increases the risk of
processor damage.
Q
There currently are no BIOS settings that begin with the letter Q.
