When the processor is operating below these limits and the user’s workload demands additional performance, the processor frequency
dynamically increases by 100 MHz on short and regular intervals until the upper limit is met or the maximum possible upside for the number
of active cores is reached.

Note
1. Only conga-TS370 variants that feature the Core™ i7 and i5 processors support Intel
®
Turbo Boost 2 Technology. Refer to section 2.5
“Power Consumption” for information about the maximum turbo frequency available for each variant of the conga-TS370
2. For real-time sensitive applications, disable EIST and Turbo Mode in the BIOS setup to ensure a more deterministic performance.

Virtualization Technology
Intel
®
Virtualization Technology (Intel
®
VT) makes a single system appear as multiple independent systems to software. With this technology,
multiple, independent operating systems can run simultaneously on a single system. The technology components support virtualization of
platforms based on Intel architecture microprocessors and chipsets. Intel
®
Virtualization Technology for IA-32, Intel
®
64 and Intel
®
Architecture
(Intel
®
VT-x) added hardware support in the processor to improve the virtualization performance and robustness.
RTS Real-Time Hypervisor supports Intel VT and is verified on all current congatec x86 hardware.
Note
congatec supports RTS Hypervisor.

Thermal Management
ACPI is responsible for allowing the operating system to play an important part in the system’s thermal management. This results in the
operating system having the ability to implement cooling decisions according to the demands of the application.
The conga-TS370 offers hardware-based support for passive and active cooling. Passive cooling is implemented in the Intel CPU via the
Thermal Control Circuit (TCC ) Activation Offset setting in the CPU configuration setup sub-menu. The TCC in the processor is activated at
100°C by default but can be lowered by the Activation Offset—for example, an activation offset of “10” will activate TCC at 90°C. ACPI OS
support is not required. See section 8.1 “Adaptive Thermal Monitor and Catastrophic Thermal Protection” for more information.
The congatec board controller supports active cooling solution. The board controller controls the fan’s speed based on the temperature
readings of the CPU. This feature does not require ACPI OS support. The only software-controlled thermal trip point on conga-TS370 is the
Critical Trip Point.
