I have herd its true and I have herd its BS.Whats correct?

Somewhat.... some chips OC better after they have been run for a bit.... Might not boot 4ghz outta the box, set it 3.6ghz for a week or so then try 4.0 it might very well work.

the cpu about 1 second is the break in period lol, no really it not a CPU break in period. But a break in period for your thermal compaond to achive the best
thermal trasfer.



similar messages are for all products and the break in period varies depending
on the thermal compound your using

Everything usually has a "breakin" of some sort...

people think engines run best right out of factory, completely untrue (in most cases)

Break in periods:

to basically run it at stock settings, don't put to much pressure on it, don't run it flat out, let it work everything in, work the kinks out if any are found then give er shit when things are running great.

I usually give most things at least a full solid week of no tweaking, no adjusting, full stability checks, sometimes 2-4 weeks before i decide to start cranking the clocks up like crazy.

Engines have mechanical parts though.

I don't put any credibility to electronics having a break-in/burn-in period.

at the atomic lvl, specially working with the size of the transistors and how much we are cramming into this small chips, physics still plays a pretty steller roll.

It's all to some form of scale, physics and whatnot working on these parts.

I mean, while we don't think anything is physically moving, it is indeed moving in some form or another. Pumping the stock voltage vs pumping the absalute maximum voltage through a cpu initially should definitely show some signs of "wear/damage" in some form or another.

You could compare a typical car engine to a CPU/motherboard as well, while the car engine has more obvious moving parts.... it's hard to conceive...

Also, people are fairly aware that contantly turning on and off electronics is hard on them, so why can't "burning in" be just as easily accepted?

in terms of physics.......if theres energy, theres always heat, if theres heat there is wear, if theres wear then there is a change,

True,

but it does make sense non the less.

Heat won't cause a chemical change in a CPU or any electronics really... not to an appreciable effect. I agree with Zelig on this one.

If there was enough heat in any electronics of yours, especially a computer, to cause chemical change? I'd start worrying really fast that you didn't see or smell the smoke caused by the large flames that would inevitably follow.

A car is one thing... moving parts and all.... your computer? Not really, no.

Its the thermal paste that 'breaks in' or 'evens out' or whatever, people just confuse that with the CPU.

HawgsHead

Thats what I couldnt understand.With no moving part how could there be a "bdreak in " period.

dont forget the movement of electrons within the electrical circuit of the processor itself, heat transfering also requires the movement of particles to transfer the heat.

the movement is there, only that it is so small that we dont see it, so we assume there is no moving parts.

Zelig

Not necessarily, heat can be transferred by radiation or conduction within the movement of particles. Movement of particles is essential if there is any heat present, but this isn't necessarily translational motion.

This doesn't infer that there is a long-term change in the composition of a processor, in conductors (and semiconductors), electrons simply hop along molecules/atoms/areas (depending on the substance), they don't necessarily change anything along the way.

You're right, not necessary, but as something gets hotter, the particles or atoms will become more vigorous.

Again, you're right, they dont change as long as they hop back, but in a particle, 1 less or more electron can change its own properties. and maybe the constant heating and cooling after some time could "smooth" out the "creases" in the CPU?

Judas

exactly.


We can argue back and forth for ages stateing if a cpu or any electronic components for that matter have break in periods. The fact remains that reguardless of size, there is movement, usually the larger the object, the bigger the movement can be seen/noticed.

In a perfect world of semiconductors, there would be 99% of the time, zero movement, but obviously in a perfect world, nothing is 100%, and being that we don't live in that world, it's usually much lower then 99%..

Reguardless.

Even without chemical change, explosions going off (as we perceive them) there is always movement of some degree. And where there is movement, there can be problems, and depending how you use the term "break in", well, will depend.


To me, every single electronic product has a break in, i usually give in general, everything a 30 day window, some components shoudln't need more then a day, others a good week.

That's like saying copper electricity wires break in. Do you break in your extension cords? No... they just conduct electricity. That's how it is.

The only chemical change wires undergo is oxidization which makes them stiff/brittle as time goes on.

There's no break in as long as there is no chemical change and like I said, if the chemical properties of the CPU changed then there is no way you'd be posting on this forum with that computer.

When things heat up or conduct electricity, that's a physical change which is completely reversable and doesn't change the chemical makeup of anything, which in turn means it has the same properties as always.

If there was enough heat to change the chemical properties then it would break in, but there isn't. So though it may be there, if at all, its on such a small scale that no one would ever notice.

Besides if this was true, processors would die of old age, and I've got a heavily abused AM33 processor that's celebrating something like its 18th birthday soon that says it that's bunk

Zelig

The rest of yours post is great, from what I recall though, processors should die eventually.

Yeah people used to tell me 10 years but I've never seen that happen ever. If anyone has actually had a processor die of old age, they might never know it... how would you know its died of old age and not something else?

Besides, 18 years and that Am33 proc still works

procupine14

eh...you know I just don't think about it too much to be honest. I just put it together and run it at stock until I can get comfortable with it and then put it to the limit when I've gotten over how much the thing cost.

H3X4D3C1M4L

Some people never get over how much the things cost

But these days CPU's are pretty cheap for what you get. The lower midrange stuff is usually astoundingly good value.

The_Neon_Cowboy

10 years is the "powerd on" lifespan!

If memory serves its called electromagnetic degradation basically electricty
slowly errodes the path it travels eventally untill the path doesn't pass electricity.

Again, were that true then extension cords and alarm clocks and other such devices would eventually just die of old age, which I have yet to see happen.
