Killed my QX6700! but New GO L720B is better!

Ok guys i killed my QX6700 CPU after 4 months at 3.6g 1.5v

The QX6700 was rock solid stable prime, orthos ect for 4 months! then thursday last I had an instand reset for now reason. re-booted and it took longer to load but everything seems laggy shall we say. then 5 mins later another instant reset and then it wouldnt boot or load a bios screen. it would sit rebooting itself over and over.

so what do i buy? is it M/B or PSU or Ram, GFX card mmmmmm well ive had this before and it was another dead intel CPU called a presler at the time. did the same thing in the same way.

So this time useing it maybe the M/B that has died and not the QX6700 i also purchased a new PK5 premium instaed of deluxe because of the re engineered CPU voltage fets and caps on the premium ( also known as the black pearl ) thats called wife confusing talk. anyway the CPU arrived today board due tomorow.

So i poped in my new Q6600 GO L720B058 pack date 15/08/07 to see if my deluxe lives with quads once more and no problems bios 0311 no CPU error code and straight to 3.6g where i was before except this time at 1.325v

this seems to be a little gem of a cpu, cant belive the voltage diffrence, my QX6700 would need 1.450v for 3.4g and 1.5v for 3.6g and it obviously ran a lot hotter. gota love these new GO quad cores as they do seem dam good chips!

So i guess the moral is if you give it to much V for to long it mightwell die, i think the QX6700 was on the edge to long and just gave up. So if anyone gets the reset of death it maywell be the CPU as its normaly everything else but!

now what do i do with my new PK5 premium!

Very nice...curious what kind of temps you were getting with the QX6700 though as 1.5v isn't anything too crazy.
 
well it was on water then phase for 2 months at 0c and water cooling after for while at 42c so it wasnt exactly hot. but i know 3.6g stable was its limit as anything above even 100mhz on phase would need 1.6v so i ran it 1.5v 3.6 24/7

anyway its definatly dead and seeing as it was only 1.5v it does seem the voltage killed it in the end. so maybe 1.35v max on box is kinda true. but iam pleased with this GO as its low voltage is even inside the max set by intel so iam well happy! cant go melting QX CPU's every 4 moths thats for sure!
 
can i ask a question? do you get a replacment from intel like in a warranty or gauretee that the chip wont go boom. i know overclocking the cpu blows it and that voids the warranty but do they know that its been overclocked if you sent it back
 
Well I guess you could send it back and intel will proberly replace it, but they might also diagnose what happened as they might want to know what killed a £600 CPU. but i cant send it back personaly as ive lapped the ICH which would void the warrenty anyway.

As i said this is the 2nd intel CPU which has died on me with no pre warning, just a reset and pow, cant blame M/B as the other CPU was in a diffrent board, with diffrent PSU Ram ect. voltage killed them both in the end.
 
If it was the voltage that killed it, there would be a lot more people killing their chips as 1.5V isn't high and a lot people are using that and more. Probably just a weak chip.

You could well be right! could well have been a weak chip, but it did run for 4 months! anyway the GO is better!

Dangerman3 are you not gutted that you just wasted £600 basically. ide be crying in my sleep if that happened to me

Well its not somthing i want to repeat on a regular basis, But in the end you have to say you have killed it, if it was run at stock it would proberly be still 100% ok

I guess if you Overclock, volt mod or anymod your PC or GFX card and break it you have to live with it, but i got a good price on this GO chip so iam happy with that.

I don't know, if it was my chip I'd be pretty angry and RMA it for sure.

He lapped it.. you don't expect the chip to go boom but sadly sometimes it happens and lapping is one thing you can't hide unless you got mad engraving skills or mad prop skills to put a new ihs on it without i being obvious.:o

If I voided the warranty on a component in three different ways and it failed, I might be angry at myself, but I wouldn't try to claim on a warranty I had no right to claim on. Although, unlike the OP, I wouldn't be over-volting a £600 component. Kudos to them for not complaining and not blaming someone else.

That's the risk with overclocking. We try to get more than we paid for, and usually succeed.

ahh i missed that part.


BTW I heard phase change systems burn out CPU's quickly if they aren't left on 24/7 due to the radical temperature differences while heating up/cooling down. Is this true? Perhaps this had somethign to do with it?
 
In theory i suppose it can stress the chips structure a lot but i've not really seen heavy evidence of this really happening on a large scale.
 
i hope this wont turn into another sudden northwood death syndrome.... :s
grats on the nice G0 cpu sickening...
hope this one fares better!

ive heard in my time that the best way make pc/components last is to keep them on all the time, when you shut down the pc the components cool then when you start up the components heat up again. this constant hot then cool then hot again cycle is bad for components shortens the life. that cycle is bad for many things in life

now since you had it running at 0c for 2months and then a major temp change to 42c, and as u all know cpu's tend to go to their operating temps very quickly not gradually(well they do on air not sure about water), i think this may have had something to do with the chip dying early. the chip was used to 0c then all of a sudden str8 to 42c that cant be good for it.

CPUs running at stock are likely to last for over a decade. At work, we have some machines with CPUs that are about 25 years old. They're switched on and off at least twice a day, every day. They're also badly cooled - they're inside a cabinet without any fans.

I doubt if overclocking and moderate heat changes (40C is a moderate change in this context) would reduce a CPU's lifespan below 5 years on average.
