Can the manufacturer tell when someone has fried their chip due to overclock?

[spittledip]

Is there a way to determine if someone has overclocked? How do system builders or manufacturers know to deny a refund or RMA unless there is a way to determine if a part has been overclocked?

No way to know...the chip will still identify itself the same. There may be a way to know if it died from too much voltage.

just a thought, are you asking this because you "know" a person who is trying to RMA a fried chip?

edit: they designed the thing and obviously have to know tell tale signs of OC fryedge.

Not usually, though in the extreme cases it's pretty easy to figure out.

Actually, there is a way to tell whether a chip has been overclocked. I can't remember the name of the process that's used to tell, but they have a way. I'm pretty sure that they don't use it for the cheaper chips, because of the time involved, though. I would guess that they would use it for one of the top of the line processors, since they cost so much to begin with.

well u could probably build in a register which will keep the fastest clock speed the chip ever was, the % of chips that do die from overclocking is probably minimal anyways (since there are not a lot of people who do overclock)

I have never heard or maybe atmost once or twice of a CPU dieing from an overclock it is meant to do.

Anyway in a country like India you can overclock and your dealer will handle it. In US, don't know.

Even that is somewhat unreliable. What if the motherboard fried and the FSB jumped to 600Mhz for a second or so before everything finally burned. Plus, if the chip is really fried, you probably will not be able to pull data out of such a register.

hmm interesting , depends, if u actually fry ur chip like on fire or smoke ... they know

but if u added too much voltage , aka vcore , for ex: then after 2 years of running 1.6v vcore for conroe and it dies, then no i dont think they would know

Im not sure how they tell..... But if you burned a chip dont RMA. Thats just cheating for your own mistake.

I?m pretty sure the guys at Intel and AMD (aka the best engineers in their profession), if they really wanted to, could strip back the metal layers, and investigate the cause for a faulty chip.

But. Would that be anywhere near cost effective. NO!
