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!

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!
 
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.
 
Jokester 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.
 
The only thing i can think of is that being under phase for 2 months might well have had an effect on the epoxy intel use to put the ICH on the CPU's.

epoxy cracks when frozen and then when it went back to water cooling the expansion of the epoxy might have cracked a core or to. but i have never read anywhere that this had happened before so its only guess work!

The thing is the cpu was 100% solid untill the reset of death, which it had never done before. it just shut off instantly and restarted to another reset after a long boot and poor performance of no longer than 10 mins. then no more, just constantly restarting with no M/B beeps or beeps from the enermax galaxy 1000w which has its own diagnostics beep system for PSU problems.

The only thing i will say is if i turned off the power for 30 mins it would post to bios load screen and sit there frozen on the loading USB devices screen, then it would reset and keep reseting untill it was turned off.

This new GO chip runs cooler and has been 100% solid since instalation in the same board with same hardware.


<maddness> can i have the QX6700

please

Well iam going to make a key ring out of it, to most it will look like junk, but for me it will be the most expensive key ring i have ever owned, cant wait to see people reaction if they ask what it is ect and i say it cost £600. never know i might get some dimwit to buy it lol but i dout it!
 
well it wasnt instantly but it had been back on water about 2 days. but i have the same opinion, i think the thermal epoxy used for the ICH on the cpu's went brittle under phase, then when run on water the expasion of instant heat when loading cracked a core or 2. then it was death!
 
Are you even gonna consider an RMA? Nothing to lose and could be worth a shot (did u scan your IHS before lapping?).

Well i bought the chip from OCUK so perhaps somone in the know will be able to tell me if its worth an RMA the cpu itself looks perfect! a nice shinny ICH nice and flat as it was a little concave to start with, only reason i lapped it really was to keep temps at the min. the chip never got hot even on water was cooled by a d-tek fuzion.

I guess your better off having a concave ICH and frying it than trying to lap it incase somthing like this happens!

Perhaps gibo can tell me if its worth an RMA
 
I havnt decided what to do with it yet, how do you go about an RMA with intel anyway! i would imagine its not easy as proberly resellers handle the rma's when it comes to CPU's

If i can find out where to rma to i may aswell give it a shot with a letter explaing why its lapped and understanding that it voids the warrenty, perhaps intel might make a little bit more effort in its ICH aplication to try and make sure they are as close to flat as possible.

so any help on how i would go about an rma with intel would be helpfull!

Cheers!
