I suppose then it's terrific the controller is setting up at 72. The
only thing I wanted to do was stress the video controller while there
were still days left in what has now become Mrs bit-bucket's brand
spanking new laptop in an attempt to get over the infant mortality
high failure phase on the failure curve. , and cascades seems to meet
my needs w/o any fiddling around with tweaking clocks so I'll let this
run on.

That's true. I don't want to push so far along where the electrolyte
departs from caps, cracks form things get brittle and the thermal
compound loses effectiveness.
This is more of a family issue but does anyone know if it's possible
to configure vista to run cascades as if it were a screen saver? It's
not possible to get Mrs bit-bucket to double click the cascades icon
when she's done. Howard
