It can only do that IF you can effectively dynamicaly alter the clock speed.
At least on my computer, it's just not possible, and it's not decades 
old... just about 11 years old. I don't say for the actual 64 bits CPUs, 
but, for 32 bits ones, most just can't have the clock turned OFF, as it 
was not software controled, but a static setting that could only be set 
via the BIOS.
