BIOS Performance Settings
Table A-1. BIOS Performance Settings
Setup Option Description
Graphics Max
Multiplier
Used to set the maximum Graphics Multiplier. Works with the built in Graphics Turbo
Boost capability. When graphics are not stressful the core will operate at the default
Frequency. Host Clock Frequency
*
0.5
*
Graphics Max Multiplier = Graphics Dynamic
Frequency.
Graphics Adjusts the Graphics VR to increase the voltage applied to the graphics core to allow
for faster graphics frequency to improve playability in 3D applications.
Maximum Non-
Turbo Ratio
Used to set the maximum non-turbo processor speed. Processor speed = the
maximum non-turbo ratio
*
host clock frequency. Maximum allowed value is processor
dependent. For example, a value of 34 is the maximum for a 2
nd
generation Intel Core
i7-2600K processor.
CPU Idle State When Intel Turbo Boost Technology is set to enable, the high performance selection
forces the operating system to request the use of Intel Turbo Boost Technology ratios
at all times. Low power setting will allow the operating system to adjust processor
ratios downward when Enhanced Intel SpeedStep Technology is set to enable.
Intel Turbo
Boost
Technology
Enabling Intel Turbo Boost Technology also enables Enhanced Intel SpeedStep
Technology and automatically allows processor cores to run faster than the base
operating frequency if the core(s) is operating below power, current, and temperature
specification limits.
Burst Mode
Power Limit
(Watts)
The Burst Mode Power Limit is the power (in watts) that can be used by the processor
when Burst Mode is active.
Sustained Mode
Time (Seconds)
This is time in which the Burst Mode Power is averaged to calculate the Sustained Mode
Power limit.
Sustained Mode
Power Limit
(Watts)
Sustained Mode Power Limit is the power (in watts) that can be used by the processor
when Sustained Mode is active.
4-Core Ratio
Limit
Displays the core multiplier to be used when four processor cores are in use.
3-Core Ratio
Limit
Displays the core multiplier to be used when three processor cores are in use.
2-Core Ratio
Limit
Displays the core multiplier to be used when two processor cores are in use.
1-Core Ratio
Limit
Displays the core multiplier to be used when one processor core is in use.
