Assigning CPU power consumption parameters
The CPU can be switched to one of the following modes via a BIOS Setup setting (BIOS setup
> Menu "Power" > "Power&Performance" > "CPU Power Management Control" > "CPU Power
Level"):
Operating mode Description
Standard
Default setting
The CPU clock is dynamically limited with maximum 3D graphics performance.
The maximum CPU power consumption is 17 W.
Performance
optimized
Setting the high performance for CPU and Graphics at the same time.
The maximum CPU power consumption is 25 W.
Note: The maximum ambient temperature must be reduced by 9 °C when in-
stalled inclined and 5 °C in all other mounting positions.
Determinism
optimized
Same as standard, but additionally optimized for deterministic operation with
constant CPU frequency.
Temperature
optimized
Setting for lowest power consumption.
The CPU clock is limited at a higher load.
The maximum power consumption of the CPU is 12 W.
