Many of these tests will detect one or more defective proces-
sors if present. It is also possible that your computer will
freeze when running one of these tests. If this is the case, you
may have a problem that requires technical support.
• Divide Test
Detects defective processors
• Task Speed Test
Determines that all processors
are operating at full speed
• Scheduling Test
Ensures all processors are
available for multiprocessing
• SCSI Test

About PowerFrax
PowerFrax is a benchmarking application that generates frac-
tals from the classic Mandelbrot set. The fractal patterns that
are shown on the screen are the result of intense floating
point calculations performed for each pixel in the image.
The length of time required to perform these calculations is
a good measure of the capabilities of the processor or proces-
sors performing them. PowerFrax has a built-in timer that
allows comparisons to be easily made. Clicking and dragging
will work in any fractal window.

Installer will install both PowerFrax and PowerControl on
