software, or handling routines are necessary when using Automatic Mode.
Note
To ensure that the TCC is active for only short periods of time, thus reducing the impact on processor performance to a minimum, it is necessary
to have a properly designed thermal solution. The Intel
®
Core™ i7/i5/i3 and Celeron
®
processor’s respective datasheet can provide you with
more information about this subject.
THERMTRIP# signal is used by Intel
®
’s Core™ i7/i5/i3 and Celeron
®
processors for catastrophic thermal protection. If the processor’s silicon
reaches a temperature of approximately 125°C then the processor signal THERMTRIP# will go active and the system will automatically shut
down to prevent any damage to the processor as a result of overheating. The THERMTRIP# signal activation is completely independent from
processor activity and therefore does not produce any bus cycles.
Note
In order for THERMTRIP# to be able to automatically switch off the system it is necessary to use an ATX style power supply.

Processor Performance Control
Intel

Core™ i7/i5/i3 and Celeron
®
processors found on the conga-BM67/BS67 run at different voltage/frequency states (performance states),
which is referred to as Enhanced Intel
®
SpeedStep
®
technology (EIST). Operating systems that support performance control take advantage
of microprocessors that use several different performance states in order to efficiently operate the processor when it’s not being fully utilized.
The operating system will determine the necessary performance state that the processor should run at so that the optimal balance between
performance and power consumption can be achieved during runtime.
The Windows family of operating systems links its processor performance control policy to the power scheme setting. You must ensure that
your power scheme setting you choose has the ability to support Enhanced Intel
®
SpeedStep
®
technology.

64
The formerly known Intel
®
Extended Memory 64 Technology is an enhancement to Intel
®
’s IA-32 architecture. Intel
®
64 is only available on
Intel
®
Core™ i7/i5/i3 and Celeron
®
processors and is designed to run with newly written 64-bit code and access more than 4GB of memory.
Processors with Intel
®
64 architecture support 64-bit-capable operating systems from Microsoft, Red Hat and SuSE. Processors running in
legacy mode remain fully compatible with today’s existing 32-bit applications and operating systems
Platforms with Intel
®
64 can be run in three basic ways :
1.
Legacy Mode:
32-bit operating system and 32-bit applications. In this mode no software changes are required, however the benefits of
Intel
®
64 are not utilized.
