I figured whats going to happen? IF and only IF it really dies, whats going to happen? the shop will take one look at the chip and find nothing wrong with it and hafta gimme a new chip? don't tell me they can "see" the electromigration or whatever it is that kills these things from overvoltage? correct me if my reasoning is wrong of course :)

Translated:

"I don't care if I kill it, and it doesn't matter that I agreed that the warranty doesn't cover failure due to overvolting the cpu. I'll just lie, steal another one and make the reseller and manufacturer eat the cost."

I don't mean to sound like youd father, but I agree with Wingnut. And you did say to correct you if your reasoning is wrong. ;) It's factually correct--you will get a new CPU covered under "warantee". The store loses money processing your return, and Intel loses a few bucks from giving out a free processor. Technically, it is stealing.

I agree with Wingznut PEZ and JamesM3M5. Just plain wrong, man.

"whats a few bucks to a multi-million dollar company right?"

Yeah, till that multi-million dollar company raises it's prices and/or lowers it's warrenty on retail products because of people like you, which affects the rest of us.

okok..cool it guys :)

I just honestly don't think it'll die at that speed. hence i'm running it there. 'sides its only 1.76v under load ..

Over-volting on a smaller micron process makes fuses the circuitry, so I hear. There are reports that if you go over 1.75V, the max voltage Intel states is tolerable for a Pentium IV northwood, it will die in a few weeks or month. And BTW, if they DONT look at the processor itself, its an easy refund. One quick check by any half decent EE and you can see the difference.

Besides, your next proc could probably fare worse (some 1.8a's cant budge past 2.2).

thanks for the advice :)
will surely bring the voltage down soon once I'm done "playing" with it ;)

Your playing may cost you quickly.....I lost a 1.8@2.52 which was good for a 12/01 packing date....It lasted at 1.83v for a week then started suffering from diminishing returns to the point it will only run at 1.58v max and 2.2ghz...So it runs fine at 1.8ghz so how do you warranty something like that!!!!;)

Likely all you will do is kills it ability to oc as high and it will take a bit not to run at default....


Is it prime95 stable for 3-12 hours???? Or are you just running some sandra???

its fully prime95 stable at 2.97ghz..working on full stability at 3ghz now..

okok..you guys really got me skared now. so whats a safe voltage? 1.8v? (is that in bios, or in windows idle or in windows load??)

SL68Q is this a new stepping for the NW? I read somewhere recently that a new one was due soon & might oc better.

Aha, so it is one with the new stepping :) ablaze00, where did you purchase that 1.8a?? Thanks!


Boxed Northwoods with the B-0 shrink
B-O Shrink

This change will reduce the size of the active part of the CPU down about 10%, from 146mm to 131mm. Intel says this shouldn't change anything, but in the past, this has helped overclockability a little.


Speed S-Stepping
1.8A SL68Q
2A SL68R
2.20 SL68S
2.26 None
2.40 SL66T
2.40B None
2.53 None

I'm from singapore! don't suppose you're ANYWHERE near me ;)

hey thats interesting, i didn't realise it was one of the new optically-shrunk cores. could you correct your link? its an ad?

Wingznut PEZ, I'm interested to know what your perspective/experience is in regards to overvolting. Since you are a .13um lithography technician, I would think that you have some experience with overclocking these puppies. Are these isolated incidences of processor failure/damage unsubstaited, or do they have some level of truth.

Any info you provide is greatly appreciated!

Overvolting is bad, mmm-kay.
</Mr. Garrison>

Seriously though... Yes, applying too much voltage to a cpu (especially over an extended period of time), can do damage to it. There's no denying that.

How much is too much, and how much damage?... Those are the questions.

Btw, me being a Litho Tech has nothing to do with overclocking. With the exception of the Engineering Samples that I've been handed, I have yet to see a single packaged cpu at my work.

In many respects, I know less about overclocking than many, many members of this board.

i normally dont look at these particular parts of the forums .... but.. i think the moral factor of taking a product back that you broke almost intentionally is wrong and i personally wouldnt consider it. I have a video card sitting next to me that somehow fried and i am not sure how it fried, it is under warranty but considering i o/c the crud out of it so many times i cant rightly take it back and feel good about myself. And no i am not rich i pay child support, support a non working wife with more medical problems than i have ever heard of, her kid, and a kid on the way.....55k$ a year salary.
just an opinion. I am glad you decided against doin this and i believe you made a good choice.

Who's Mr. Garrison? :confused:

Anyway....I guess I don't know what a lithography technician does then. I would think that they take a process and push it to its limits at some time or another, but I suppose not. :eek: So, do you think that this "electromigration" or whatever you wanna call it is going to become a larger problem as processes continue to get smaller? And is there a way to lessen this effect?

Oh...sorry. Back on topic. Great overclock, ablaze00! :p

As the process and parts get smaller they will be sensitive to higher voltage...However each die shrink should result in lower vcore in which to run it. I would think this doesn't mean the days of ocing will be done.....IE


Lets say .09 will run at 1.35v at default...It is likley we can go up to 1.5-1.55v without significant danger...
