E8400 Questions

Hey i have some questions about the E8400.
1. How long will this chip last at a constant temp of 70 C? Or 80 C?
2. How long will this chip last at a 4.0 or 4.5GHz overclock with good cooling?
3. How long will this chip last at 1.4 and 1.5 Vcore?
Thanks!

Notes:
1. I checked Google, no definite answer.
2. Please don't tell me that "45NM over 1.35 Vcore can break it you kno"
I already broke a chip, i know, you do not have to tell me.

1. depends on whether you are talking core temp or cpu temp. core temp, forever, cpu temp - hard to say.
2. totally depends on the chip. Better chances with E0 than C0.
3. 1.4, a long time, exactly how long will depend on a lot of stuff like specific chip, cooling, how clean the power is etc. 1.5, probably not terribly long, but again will depend on a lot of other factors. If its pushing high temps with dirty current and craking at 100% 24/7, not so long. If its on dry ice, not pegged to 100% all the time and fed really clean current it will likely last forever.

it would last about 9 years or lower at 1.4v, same for the temp and the clocks can last u up to 11 years. btw it's not good to go that far with the e8400.

How did you break the other one?

I think you can find a happy medium between 4-4.5ghz where the volts are less than 1.4, temps less than 70c and the life of the chip won't be an issue.

Not to pick on ya but how do you know this? Random guess I assume.

The 8400 hasnt even been out for 9 years and noon knows exactly how long they will last with the temps and voltages that the OP suggested.

OP your questions are just going to get alot of guesses because nobody really test for these things. By the time you found out on a cpu or two how long it took to kill it at 1.4vcore at 70c it would be so obsolete that more then likely very few people would benefit from the research anyways. Just companies but they tend to not OC very much any how.

Thank you!

also, i broke my other CPU because i used it for a bit at 1.8 Vcore on water cooling.. not enough.. got really really hot, and died after a week or so.

1. Constant 80C?..i wouldnt say much over 6 months to be perfectly honest...
2. My E8400 is at 4ghz and 24/7 at 1.32v with scythe samurai cooling and 40C max
3. 1.4v maybe a while, 1.5v not as long to be perfectly honest, they set the maximum at 1.362v for a reason to be fair.

im just wonderting why you would consider allowin the cpu to run at 80C? With a good after market heatsink you can easily run a e8400 at 4ghz under 40C...

Average chip lifespan is ten years at stock speeds. I have heard people mention that a high OC can take as much as half the life off of a chip but I don't know if it has ever really been tested or proven. Chances are you will replace the chip long before it's going to die. Provided you don't accidentally kill it again.

Thats hardcore. 1.8vc will burn any chip up.


Anyway, there is only one way to find out. Just keep it cool (under 65c) and you should be safe. Degradation could become an issue when it gets used to high vcores, and may periodically want a boost to maintain.
