life span - Page 3

post #21 of 34
he said slow it down, if the chip "cracked" then the transisters wouldn't have connections and current wouldn't flow.
Until there is an open circuit the current flows better, i.e. quicker, than at higher temperatures.

Also i've never seen metal crack because it was too cold. If it was -100 C and then went to 50C then it would break.

well, that explains it a little better... I jumped to "crack"... But they could slow down, it is a possibility.... At absolute zero, everything freezes completely. I bet a CPU could do this before that point, though.

You can't reach absolute zero. Ever. No... not even then. It's against the laws of physics and therodynamics. The way current works is that it always works better at a lower temperature. At lower temperatures the atoms are closer together and therefore the electrons are more tightly packed and the current flows better.

From the metal standpoint: the metal stretches unless you heat one part up too quickly or cool it too quickly. Metal is an elastic material. If we made chips out of plastics , a ductile material, then they would crack if they were too cold.

ive seen plenty of CPUs die..............by my hand.

ive taken many a hammer to my old PC's that i get free from computer corps.

ah the fond memorys of seeing memory get blown to bits.

It has been my experence that the Bathtub curve can always be applied to all hardware components from the case to the proccessor. The bath tub curve explaines to us that any given component can pass through 3 life cycle stages. Early failure Period, Intrinsic Failure Period, and Wear out failure period.

The bathtub curve is calculated using the folowing formula (r / N * i) Where r is the rate of failure and N is the number of units and iis the increment is used to determin, h(t) or falure rate. The calculation can be modified to extend the period out to weeks, months or years.

An example is

if N12 units survive to start the 13th month of life and r13 of them fail during the next month (or 720 hours) of life, then a simple empirical estimate of h(t) averaged across the 13th month of life (or between 8640 hours and 9360 hours of age)

A graphical example of this is seen in the folowing graphic.

Or at least thats how it was explained to me.

I know the feeling 14 year old Pentium Pro goin strong!!! Hmm overclock.net looks good with 200mhz

Yeah, and it has a larger cache than my laptops Celly.

Your curve states that the beginning is the most failure....

This is true most components if they are going to fail will fail within first few days. After the initial burn in period is when the curve flattens out giving the long life of components we have been reading about. It is only after this long period of time that the curve starts to rise as the component wears out. This is how we come by the name bathtub curve.
