    Re: CPU burn in, myth or reality?

    then you cant weed out the chance of aimbient temperature being a factor

    Well, it's cooler now here in Utah than last August, but my temps don't read all that much different, maybe a degree or two cooler, but no difference at all when running prime95. As for the increase in htt, I think it's genuine, cause nothing has changed in the system, nothing, at least in terms of hardware. I simply followed the advice of some fellow here at the forums who noted that sometimes ocing a system is a gradual process and be patient. I took the advice, was patient, and sure enough, it's slowly getting up there. And yes, I did not go through any periodic "burning in" process. I simply used the computer over time and gradually was able to bump up the htt.

    In contrast, one of my 2600 Mobile XPs jumped right to 2.6 practically out of the box. Sometimes it's the luck of the draw.

    Re: CPU burn in, myth or reality?

    Just to clarify, there does seem to be a genuine phenomenon of the thermal interface bedding in. If you've done a good job however, the effect is minor, and anyway, this only takes a couple of days and is only good for about a 2oC CPU temp drop. That "burn-in" I accept. No, the one I think is rubbish is the one where people seem to think some kind of electron effect is happening.

    And can we cease the abuse of other members please.

    Re: CPU burn in, myth or reality?

    umm burn in works but doesnt require more than 12 hours of running it hot
    i dropped 3 degrees after burn in
    32/33 idle and 44/45 full load day i got it
    27/29 idle and 41/42 full load the next day

    but i also use super secret mix of thermal compound

    My advice is to apply them in that order as well...

    oh come now..... you can't see those little electrons burning a path in that copper substrate?

    or are the teaching the "hole flow" today instead of electron flow!

    I have not heard of hole flow since I went to Electronics school in 1965.
    It is a plausible explanation for what happens inside a transistor

    Re: CPU burn in, myth or reality?

    Well today the CPU burn in is more a thermal compond seating.

    20 years ago you needed to do a burn in prior to production due to the number of failed devices.

    The Idea was to run the sytem for 72 hours and if the system was still working you had a winner!

    Today the quality control and systems are more reliable and also much smaller

    I normally do a "burn-in" just to set the thermal compond and get my baseline testing done so that I can use the results in posible trouble shooting later.

    So really Burn-in was a requirement in the early days but with todays systems are just a hold out from the past.

    Having said that, the only exception is if you call Pre-Production testing for servers prior to placing online a Burn-in.

    It works but you should be patient

    and of course all CPUs are not same!
    For my personal data gains for AMDs are 30-50 MHz OK this is nothing.....
    The most important is Vcore decrease for the same MHz.
    Anyway if someone follow my guides then he/she must read carefully the instructions and of course he/she should visit OcTech forum for latest updates etc....
    Moreover I stack Gorki's thread see it here

    i went to electronics school in the navy (1986), we were the last class to be taught electron flow, and all subsequent classes had hole flow. they tried to teach our class both, and needless to say, we had alot of confused squids!

    i agree with what is being said about burn in..... it is to "cure" the thermal interface material, and test for reliability. most components that will fail due to being loaded will fail in the first 24hrs......

    carry on! [salute]

    Used to be known as the "smoke test" - if you saw smoke the device had failed it...
