If you throttle the clock rate the processor voltage can be as well.
Reducing the clock rate reduces power less than linearly (constant
leakage, which is significant). Reducing the voltage reduces the
power by the square.

Bingo! He's said as much in previous dreams.

Hard disks have a high startup/spinup current, quite a bit more than
normal operating current , a PSU is more likley to fail at start up a
change in throttle on a PSU would be small in comparison

I don't see this being done on desktop CPUs.

Have you looked? AFAIK, the Apple G5 PowerMac did. ...at least
they sure demanded the support for it. Everyone else was going the
same way because of the ridiculous heat the processors were throwing
out.

That is ridiculous.
A HUGE number of motherboards not only allow memory timing adjustments.
Most, if not all of those also have provisions for reducing or raising
the voltage setpoint of specific rails..

The equivalent of the "water hammer" effect in electronics is reverse
EMF. But were that the problem, a lot more of us would have this
problem. And, while I'm at it, hard drive spin up creates a lot more
reverse EMF than cycle throttling the CPU.
And, yeah, it's a conspiracy. You're not paranoid. The whole world
really is out to get you.

Wrong again, AlwaysWrong. How *do* you do it, Dimbulb? Modulating
the power rails is a well known method for reducing power
consumption in laptops. ...unless you don't consider
microprocessors to be "digital logic".

First of all I use my computer more then people use their computer.
Second of all only few people have the amd power monitor tool installed.
^^ That's my bet !
