4.2. Power Consumption
The goal of this description is to provide a method to calculate the power consumption for the CP6007-SA or CP6007-
RA baseboard and for additional configurations. The processor and the memory dissipate the majority of the thermal
power.
The power consumption measurements were carried out using the following testing parameters:
CP6007-SA or CP6007-RA installed in the system slot
Ethernet ports not connected
CP6007-SA: 32GB memory down + 32GB SO-DIMM; CP6007-RA: 32GB memory down
+3.3 V, +5 V, +12 V and -12 V main supply voltage
2.5 m/s airflow
The operating systems used were uEFI Shell and Windows® 10 Pro, 64-bit. All measurements were conducted at an
ambient temperature of 25 °C. The power consumption values indicated in the tables below can vary depending on
the ambient temperature. This can result in deviations of the power consumption values of up to 15%.
The power consumption was measured using the following platforms:
CP6007-SA: Intel® XEON®-W-11865MRE, 2GHz
CP6007-RA: Intel® Xeon®-W-11555MRE, 2GHz
The power consumption was measured using the following configurations:
Work load: uEFI Shell
For this measurement the processor cores were active, the graphics controller was in idle state (no
application running) and Intel® Turbo Boost Technology was disabled.
Work load: Idle (Win 10 Pro)
For this measurement all processor cores were in idle state (no application running) and Intel® Turbo Boost
Technology was disabled.
Work load: Typical (Intel PTAT)
For this measurement all processor cores were operating at 70% work load while Intel® Turbo Boost
Technology was disabled. These values represent the power dissipation reached under realistic, OS-
controlled applications.
Work load: Maximum (Intel PTAT Tool)
These values represent the maximum power dissipation achieved through the use of specific tools to heat
up the processor cores. For this measurement Intel® Turbo Boost Technology was disabled. These values
are unlikely to be reached in real applications (all cores were operating at 100%).
To support the extended temperature range (+70°C), the maximum power consumption of
the processors must be reduced. The maximum power consumption of the Intel® Xeon®
W-11865MRE and Intel® Xeon® W-11555MRE processors can be reduced using the Power
Limit Reduction feature (cTDP). This feature can be configured via the kBoardConfig uEFI
Shell command. For information on this command, refer to the Chapter 9, uEFI BIOS.
