Does burning in a cpu actually work?

Hi,

Can someone explain the process please.

I understand that overtime after burning in a cpu that this can lead to it the cpu needing less volts etc... for the same clock speed.

Its like the cpu gets trained somehow to respond to less volts.


Thoughts.
 
Well, my old FX57 ended up doing 3.6GHz for Superpi 1MB runs after having it for a good few months when originally it wouldn't go over 3.5GHz and the only reason I can come up with is that it was burnt in.

I've definitely had RAM though that's been burnt in, BH5 is well known as far as I'm aware for burning in over time, letting it hit higher frequencies than when it was first bought.

Some suggest that it may have something to do with dopant stabilization and the dielectric properties fully forming in the tiny, in-circuit semi-conductor junctions, capacitors and other components....

Sounds more like a quote rather than you know what you are talking about there easy!! ;)
 
when i got my golden stepping LDBHE 0601UPMW 3800X2 that would suicide at 3.4 when i first got it but after some burning in time (lots of heavy prime runs etc) it would suicide at 3.55ghz. (Both on phase) So yea i agree it does have some affect.
 
interesting. will try clocking my opteron higher next year. hope i can get another 100mhz out of it on stock volts.

dang it ill try clocking it now. let me see if i can get another 50mhz out of it.
 
right 305htt allowed me to get into windows and ran super pi twice fine.
but ran snm for about 10 secs and the machine bsod. now trying 301htt so im at 3010mhz, snming so far for 7 mins and it seems to be ok, but need to run snm for longer for the verdict. temps are at 48c on the cpu thanks to the big typhoon. case is at 31c since i put the heating on in the room to warm things up and simulate a summer environment.

was shocked at how it even booted into windows at 3050mhz, it never did that before.

dang asrock board has me stuck at 1.45v no more vcore allowed :(
 
I think its the other way round :cool:

That is a CPU should perform its very best the moment it is installed, but slowly over time it will degrade due to electromigration.

Perhaps it is because people learn about their systems/mobo/etc and are able to get better overclocks because they have fine tuned all their settings/improved their cOOling etc?

Hmm maybe its also connected to the new car theory, i.e a cars engine is meant to work better after you done a certain amount of miles.

CPU (or Memory) burn-in is a nice idea but i don't think its real, so in theory I am saying a new CPU will overclock better than one which has been 'burnt-in' :D
 
You won't get "electromigration" within the lifespan of a cpu, if at all (I reckon :) ).

I don't think burning in has any effect on cpus.

that all depends on how you treat your processor, i.e. overvolting, etc. will cause electromigration to occur in a shorter passage of time than left at stock, and i think it was a quote, i have heard that before, something about overclocking intel celeron processor and 'burn-in' :p
 
ok i see the consept of burning it in,

if, (this is just a idea,) but if i made a second pc, a E6600 or somthing, and ran orthos 100% load for about 10 weeks streight at the highest possible overclock, would it then clock higher when i went back to try and overclock it?

(btw not going to try it, havent got the cash :D )

well who knows if that would work, does anyone here know how 'burning-in' a processor works, on the molecular level i mean? :confused:

Edit: and with regards to doping, how could that have something to do with why processors overclock further after being 'burnt-in'? i mean all doping does is intentionally increases the conductivity of the semi-conductor in a set area of the material, i don't understand how the application of infra-red photons would change this, unless you were somehow adding more dopants to the material :confused:
