Hello,

I have a new theory how the power supply got damaged:

AMD's X2 3800+ dual core processor has CPU Throttling.

I downloaded a special AMD Software tool called AMD Power Monitor or
something like that.

Which throttles back the CPU when it's idling... then when it needs to do
work the cpu is throttled up.

So on idle the processor will work at 1.0 volts... and then when it's busy
it will work on 2.0 volts... maybe even voltages between it.

These voltages fluctuations occur very rapidly.

Think of it like this:

You turn on the water... you turn off the water... then you turn it on
again... then you turn it off again.

If you do this at the right pace... the water in the tubes will start to
pound on the inner tubing... and sooner or later something is going to
break.

This is probably what is happening inside the electronics.

It will work for a while... but after one or two years of heavy usage...
kiss it goodbye !

Fluctuations in temperature seem to also cause problems for gpu's in
laptops...

Try doing that with your teeth fillings... ouch

Crappy hardware nowadays, me very sorry I bought this crap.

But it is powerfull and with some nice Skybuck experience and knowledge it
might work after all.

So I gotta find a new power supply... and leave the processor at always 2.0
volts to prevent any damage or temperature fluctuations.

Don't know what happens to gpu though... though the 7900 gtx seems to be
able to take quiet a beating... don't know about the components around it on
the motherboard though

You've been warned people =D

The clock rate is throttled, not the supply voltage.

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.

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

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 key here is changing voltage on the fly. Your argument is
irrelevant.


You are irrelevant. "Dynamic, on-the-fly rails" and digital logic
doesn't go together, dingledorf.

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 !

Third of all no one seems to have all the problems you have.

I've never met a soul that has the issues you've had. Which would lead
me to believe one of several things: the parts were bad before you got
them, failed naturally due to imperfections, or they weren't hooked up
correctly (which hopefully isnt the case). Saying that CPU throttling
damaged your power supply is a long, long stretch... a big enough
stretch that hopefully you would realize that something else must be
the issue.

In general parts do fail every now and again, but keep in mind they
are designed to NOT fail (and function together). CPU throttling by
definition should not damage anything on your computer.

You think? My quad core is loaded at 100% 24hrs/day on distributed
computing projects.

Third, you use Windows.... that is probably the root of your problem!

Sleep with a reduced rail voltage is quite different from full bore
operation with sliding rails.

No, Dimbulb. Fully operational with reduced voltage for low power
operation. Reducing the clock only gets a linear reduction in
power, and zero savings if you measure CPU cycles per watt. Reduce
the voltage at the same time and the power goes down by the third
power.

So no. When the mobo throttles voltages, it also throttles the cloock,
and no, that is NOT an example of a varying rail on an active digital
pathway.

Wrong again, Dimbulb. They've been modulating power rails for at
least five years.

It may be of interest that some processor intensive SW has throttling
methods that involve intermittent 100% processor duty control methods.

Some months ago, I scoped local regulator and auxiliary regulator
supply deviations under this regime on two different 1ghz AMD
processor motherboards, operating off of generic supplies of varying
age. I found no deviations that would induce or explain hardware
abnormalities occuring at the time.

Hope this helps to relieve any anxiety that the OP may have developed
re this issue.
