Q6600 burned

nlel1975 · 22 Jul 2008 at 15:17

I tested my q6600 yesterday at a cousins house, we tried up to 1.4v on stock cooling outside the case with big fan on top temps got to 80C under load, then we used a better cooler and 2 big fans either side of it and upped the volts to 1.45v and were getting temps of 50C under load.

So we powered down the system and I removed the CPU, then today while I was cleaning the gunk off I noticed the heatsink had left an impression on top of the CPU and on the underside there were signs of burning near some of the gold contacts!

I don't have the rest of the parts for my machine so I don't know if it still works but I wonder how could this burning have taken place, I ran my old q6600 78C under load all the time and up to 98C for over 2 hours once and it never failed on me, I never checked for burning as it remained in the socket when I sold it but I`m worried now, can overclocking cause damage.

Yes. Your pumping more power/current through a device than it is intended to use/draw. It's like modding a light bulb to be brighter and expecting it to last as long and not burn out.

Overclocking carry's risk.

It will probably still work as if it had of died we surely would have noticed this while still using it, it must have burned while it was in use but I guess not enough to kill it yet but I don't know I wouldn't be surprised if it didn't POST now.

1.45 you say.

I've runned 2.0v on e2200 ;p on air ;].

Honest to GOD all we gave it was 1.45v under load which is at the extreme end but we had good cooling 50C under load, but I`m not sure that was an accurate reading becuase we tried another chip just after and it was getting at least 10C more, maybe something was awry with the fitting of the heatsink after we replaced the stock cooler... I don't think the stock cooler at 80C would have caused this.

you would be extremely unlucky to have damaged it at those volts and temps

Yeah like I say we had no problems up untill we powered it down the last time, it was only when I noticed the burn marks today that I started worrying that it may have expired, chances are it is OK as it would have died before we powered it off and we would have noticed its just a shame I have to wait a week to find out one way or the other.

I would probably blame the motherboard before the chip, unless you're really unlucky. And if you really are that unlucky then I would probably put down to a faulty chip rather than a bad overclock.

Well the chip certainly has "burnt in". I reckon I might have got away with it this time, the chip obviously got too hot but may of saved itself from any real damage... I do remember at one point when we were testing it the machine failed to boot windows one time, I`m thinking that is maybe when the motherboard decided to shut the chip down to save it. I dunno we shall have to see, I will just be optimistic.

I'm not suggesting that 1.45v is too blame.. purely based on his comment of "...can overclocking cause damage".

Did it go like this?

Nah, I now think it most likely happened when the temps reached 80c and it may of happened to my old chip as well but I never noticed becuase I never removed it from the socket and as it continued to work I never suspected it had burned.

I thought a burned chip would be a dead chip but it is not necessarily the case, with my new cooler and case I should be able to keep the temps below 80c so further damage shouldn't occur.

That shouldn't have given the chip any lasting physical damage. I've seen a C2D chip get so hot it "pings" and changed colour, and even that still worked.
:cool:

Well at best I`ve invalidated my warranty (not that I had one) as it was an OEM jobbie off a popular auction site.
