How come no one talks about CPU degradation? My 920 D0 is degrading.

post #1 of 178
Thread Starter 
I always knew that CPU's have a certain lifespan, but I never knew they were that short. I've had my 920 D0 for a year and a half, and it's already showing signs of degradation, so I'm temporarily running it at stock speeds now. I never ran it high voltages (1.27V) and now it's degrading. But I did stress test it a lot, and I think that's why.

How come no one here really talks about this? Seems like everyone goes on their marry ways and overclocks their machine to hell and back without even thinking about the consequences. Many people even have their vcores set much much higher than mine's, but what are you gonna do, every chip's different I guess.

This @$%@$% sucks. I spent a lot of money on a loop and a new case, and I now I'm afraid to overclock it cause it's gonna help speed up my CPU's already imminent death.

Intel has a 3 year warranty on their chips. That means that it's guaranteed to have error-free work for the next 3 years, assuming that it hasn't been overclocked. What's overclocking do? Kill that time in half? What's the point of overclocking if our chip's are gonna degrade or die off in a year and a half or two? What's the damn point? I thought I was gonna be able to run my chip at 4Ghz 24/7 for at least the next 5 years, but that's not happening anymore.

I always knew about CPU degradation and longevity in the back of my mind, but I never knew the consequences of even moderate overclocking were that bad. This is warning to the other relative noobs like me around here, don't expect your CPU to last a while if you overclock, even if it's a moderate voltage and you have watercooling.

This sucks!

I'd say it's made pretty obvious in ANY overclocking guide or discussion that what we do has risks, including damage to hardware and voiding of warranty.

When you start moving parts out of spec, you accept the risks involved. If you didn't have a benefit from overclocking, you should have moved back to stock if you can't accept risk.

It may sound blunt, but nobody is going to feel sorry for you. We may be sorry you had a failure, but nobody here should pretend that you can run hardware out of spec without accepting risk.

I did a lot of stability testing, but now that I think about it, that's not a good reason why it's degrading, since many people with much higher vcores fold almost 24/7 with their machines

Well honestly lots of people DO talk about CPU degradation, but most don't go that quickly. Yours could have to do with a lot of factors, and could even be something like the board capacitors degrading, who knows? Pushing a chip so much faster than it was meant to run will have downsides, but most people that do push their chips that far don't really worry about it because they don't use the hardware more than a couple years.

I had a C2Q a few years ago that I pushed to the limits, but never worried about it, because within 2 years I got rid of it. I will probably change out my current processor in another year or so, no biggie. Just remember, when you push hardware, it always has consequences.

Maybe you got unlucky.

1.27v is actually very safe. The VID range for the i7 920 is 0.800V-1.375V.

That means that some i7 920s come with a higher voltage right outside the box.

I'm not asking for sympathy, and I don't need it.

And I understood that overclocking comes with risk, but this soon???? With such a mild voltage???? Ridiculous.

Quality of the chip u had was poor. There are some exxxx dual cores knocking round with hefty overclocks. You've been unlucky...

OK, So I'll ask the Million Dollar question...... What makes you think that your i7 is degrading?
