I mportant Technology Information
2 2 B
The following technological information is designed to give you a better understanding of some of the
features offered by the coolMONSTER/PM. This information can be referenced when reading the
Appendix A: System Resource Allocations and Appendix B: BIOS Operation sections that follow. There
also are references to additional documentation that will help you develop a better understanding of the
technical information. They are listed in the Appendix F: PC-Architecture Information.
23.1
M ax CPU Frequency setting
9 2 B
Kontron Embedded Modules currently offers four variants of the coolMONSTER/PM. They are the
1800MHz Pentium® M versions and the 800MHz, 1000MHz or 1500MHz Celeron®-M version. Additional
processor support is planned. These variants use a smart BIOS with the capability of identifying the CPU
that the module is equipped with. Another feature of the BIOS is its ability to offer the user the option to
set the maximum CPU frequency based on the Intel® SpeedStep® technology.
Note:
Celeron® M processors do not support this feature.
The different Max CPU frequency settings available for the different modules are as follows:
800MHz:
®
1000MHz:
®
1500MHz:
®
1800MHz:
®
Notes: Selecting frequencies higher then the default may cause the system to reach "Critical Trip Point" and
shutdown if a proper cooling solution is not used. Always ensure that you use a proper cooling when selecting
higher frequency settings.
Refer to the Power Menu section in the Appendix B: BIOS Operation chapter of this manual for more
information.

T hermal Monitor and Catastrophic Thermal Protection

23.2.1
T hermal Monitor
1 4 4 B
The Thermal Monitor within the Pentium M processor helps to control the processor temperature by
activating the TCC (Thermal Control Circuit) when the processor silicon reaches its maximum operating
temperature. The temperature at which the Intel Thermal Monitor activates the TCC is not user-
configurable and is not software visible.
The Thermal Monitor controls the processor temperature by modulating (starting and stopping) the CPU
core clocks at a 50% duty cycle (TM1) or by initiating an Enhanced Intel SpeedStep® technology
transition (TM2*) when the processor silicon reaches its maximum operating temperature. The mode is
selectable in the BIOS Setup Utility.
Maximum operating temperature activating TCC:
