Power Consumption
The power consumption values were measured with the following setup:
•
conga-IA4 COM
•
modified congatec carrier board
•
conga-IA4 cooling solution
•
12 V input voltage for S0 states and 5 V for S3 and S5 states
•
Microsoft Windows 7 (64-bit)
Note
The CPU was stressed to its maximum workload with the Intel

Measurement Description
The power consumption values were recorded during the following system states:
System State
Description
Comment
S0: Minimum value
Lowest frequency mode (LFM) with minimum core voltage during
desktop idle
The CPU was stressed to its maximum frequency
S0: Maximum value
Highest frequency mode (HFM/Turbo Boost)
The CPU was stressed to its maximum frequency
S0: Peak value
Highest current spike during the measurement of “S0: Maximum
value”. This state shows the peak value during runtime
Consider this value when designing the system’s power supply to
ensure that sufficient power is supplied during worst case scenarios
S3
COM is powered by VCC_5V_SBY
S5
COM is powered by VCC_5V_SBY
Note
1. The fan and SATA drives were powered externally.
2. All other peripherals except the LCD monitor were disconnected before measurement.
