need opinions on Q6600 i just purchased

i just bought a used Q6600 and upon getting it in the mail today i discovered it had been lapped. just enough that it is still shiny but no wording is visible. the person i bought it from never told me it was lapped and to be truthful i did not ask. would you be upset or is it no big deal? i have not had chance to install it yet, waiting for some parts.
 
What were the conditions of the sale ? What were your expectations ? Did you have a DOA guarantee ? If the deal was for a working Q6600 and it works, I wouldn't worry ...
 
It is fair to assume at this point you have purchased a Q6600 that has seen some aggressive overclocking and no doubt a tad bit of the juice (voltage) has flowed thru its transistors. Can you say "beat like a rented mule"?
 
I read once that someone had to gradually change the voltage for a processor over time once it was overclocked to make sure that it remains stable. That being said, I wonder if you should overclock it to assure that it will remain stable. I'm just speculating of course.
 
How much did you pay for it? If you got it for less then the average used Q6600 and it works as you expect, then WGAF? <- may have just invented Who Gives a "fill in the blank".

As some said above it does look like a you purchased a unit that at the very least has seen a good amount of OC'ing/Benching...
 
Well you definitely should have been informed up front about the condition of the chip. Try it out and see if it works for whatever you're trying to do, running stock or OC'ing. The lapping probably just shaved your temps down a few degrees 🙂 , I wouldn't be mad if it worked fine after a good round of stress testing.
Contact them, maybe the seller will be willing to give you a discount off for the altered condition of the chip.
 
this is what their post read for the description - 155 Shipped -- Retail Intel Quad Q6600 G0 L726A343
With unused heatsink and original box. Overclocked to 3.7GHz (+/- 100) with 1.5v -- YMMV.
 
Hmm, i would be bit pissed, but it depends what you payed for it, and what the arrangement was. may as well try it, and see how well it works. Also, since its already lapped, if you got good cooling, why not oc it? perhaps it is a decent deal after all.
 
Your options are to use it or return it, simple, pick one. If it works fine, I say he saved you the trouble of possibly lapping it yourself later but if you'd prefer the "OEM/Retail" look, return it.

Well from that know its no longer under warranty. So if you got a doa guarantee, check it out. If it works, you have no recourse, morally or otherwise. If its dead return it. Simple. If you didn't get a doa warranty, you have no options, try to use it.
 
The seller should have mentioned it. But IMHO its not a big deal as long as it was done correctly. When you buy a used chip off the forums it is usually a pretty good bet it has been OC'd, part of the minus's' of used stuff. That one in particular looks to have been used up pretty good but these 65nm chips are pretty resilient so I wouldn't expect any trouble from it. Just run it at stock speeds at the stock voltage. Fairest way I can think of to check for degradation.
 
On the one hand, he saved you the trouble of lapping it yourself if the IHS surface shows mostly bare copper. If it still shows the nickel-plating, he saved you part of the work.

The rest is speculation. If he says "1.5V," it may have been a "set" value that resulted in a reported voltage even below 1.4V. Then it is also speculation about how long he ran it that way. The G0 steppings appeared a year ago -- almost exactly.

From my quick lookup at NewEgg, you may have saved $45. You have certainly lost "certainty" over the condition of the item. Only way to find out is run the sucker, push it up to the easy 3.0Ghz over-clock, run 20 iterations of IntelBurnTest with known, fixed voltage settings you will find in threads here. If it fails, you swallow the $150; if it doesn't, assume that the previous owner had less than a year to damage it.
 
If you knowingly by a chip that was run at 1.5v, I wouldn't worry about the lapping .. It's like buying a used police car with a new paint job...

Sums up thread nicely.

Hopefully being ran at 1.5V after being lapped means it wasn't tested at 1.6V before being lapped.

(i.e. be concerned with what motivated the prior owner to decide they needed to lap it in order to hit 3.7 w/1.5V...did it come from many a failed OC attempt at 1.6+V with too high of temps? etc)
 
well it is in and running. all seems well, i ran some test and checked the voltages. all is normal. i want to thank all that replied and lent their opinion on this :beer: :thumbsup: i am going to test it throughout the next couple of days but my instincts tell me it is fine 🙂

Well this is a great thing. Congrats. Also, I have noticed in another thread that your vid is 1.262v, the same as my Q6600 and I have it comfortably set at 3.4 with 8G of ram. I would hope you can get the same OC out of it and if so, not only will you have a speedy chip, it will run cooler too. Again congrats! 🙂
