CPUIdle

No_Style · Mar 28, 2003, 08:47 PM

Ever heard of it? At first I was skeptical about it actually working, but it does work. Brought my CPU down 2 C when idling. I'm still testing it out, but I just wanted to know some other people's impressions with it. Should I have it enabled on all the time or what?

you should leave it on yes

Vampyromaniac · Mar 28, 2003, 11:54 PM

I have it, but I haven't experienced any difference

It could certainly be due to something else, though (case airflow.)

Large temperature fluctations are what kills the life of a processor. When a processor is constatly run at the same temp all the time it's life lasts longer. Therefore it is always better to stress the CPU... folding is an option. Or seti@home

Actually, DriveEuro, the more you constantly run a processor, the more you wear it out. Heat cycling does play a role in the MTBF of processors, but electromigration and other electrical processes wear out the transistors before heat cycling will damage the core, so keeping a high constant temperature just wears out the transistors in your proc faster through whatever-it-is-that-kills-processors-before-their-time...

EDIT: Higher voltages, which do cause higher temperatures, are particularly deadly, since they exponentially increase the electromigration rate in your processor...

lets take for example the average processor, idle say between 35c and 45c (depending on cooling). and full load between say 40c and 60c.....

the fluctuations between these figures will in no way kill the life of a processor and running seti or home will not prolong the life of your processor. id like to know your technical source for this information Drive.

Question: How about high voltage and low core temps? How does that play out? I'm guessing temperature is the real CPU "killer".

ToshiroOC · Mar 29, 2003, 06:54 AM

Core temps really don't do THAT much - they aid stability and wear, but once you get past a certain point with voltages, somewhere around 2v, you start getting serious electromigration, which is where electrons beat the crap out of the wiring between transistors at corners and turns in the wire, and eventually sever the wire, making the transistor non-functional. I'm not sure how temperatures effect things, but I think that high voltage trumps temperature...

From what I have read, I would agree with this.
Nice explanation, btw

I would have to agree with that also....

I've heard of this too. Mostly with P4's where the stock HSF gives a low idle temp but heats up like a motha under load. Most P4's that die out at over 1.75v is because there's a 30 degree swing in temps during use. If you look up afew sudden P4 death articles they talk about this

DriveEuro · Mar 30, 2003, 05:15 AM

Yeah, see. If you have it idle runs like 20C, then run it stressed at like 40C.... That can't be good.

Ah, but that is over-volted

I think that would be the stronger factor there.

Isn't 20ÂºC around room temperature?

Ohh sorry, I didn't realize that there were still people out there that didn't OC

I oc. I know what I am saying.
