Processor Speed and Temperature 149
D • Processor Speed and Temperature
The processor speed and the temperature are inter-dependent. This means that
for a given temperature, a maximum processor speed is achievable before
throttling, and conversely for a given processor speed before throttling, a
maximum temperature is achievable. This is further affected by the build level,
which dictates the maximum ambient temperature at which the board can operate
(See
The processor speed can be set from the BIOS via the Advanced Tab on the Main
Menu.

Table D-1 Maximum Operating Frequency versus Max Temperature for Quad Processor
NOTE
The thermal data from the table above was taken while the units were running multi-threaded test
software used to stress the CPU, memory and I/O functions simultaneously. This test load is generally
heavier than a standard embedded application. There may be some variance in the user’s thermal results
based on the end application. Please contact Abaco Sales or Technical Support for any further thermal
details or discussions relating to your specific application.
