I was looking at Intels processor finder and noticed the following:
(Thermal design) Power: 0.80v - 1.3625v

Does this mean that i bust my CPU if i run above 1.3625v?

Best regards!

Any voltage setting above what is specified is sure to damage your CPU, even if you house it in the freezer.  I think the CPU is guaranteed to bust at anything above 1.45-1.5v.

 
So i can't take it above 1.3625? I think it was called the Thermal Design Power, though i am not sure.

Well, you can damage your CPU by setting applied voltage near or at the unit's outer limits of capability.  Yes...you can shorten the life and permanently damage the CPU with excessive voltage.

I'd like to know what processor type you are talking about!

The E8xxx's upper limit is 1.3625v while the older 65nm C2D's upper limit is 1.5V. Going above 1.3625V on the 45nm C2D is like going over 1.5V in the 65nm C2D. So short answer, no.
 
If you want to, expect less than 3 years out of the cpu's life.

But to get to 4ghz on my E8400 i need to get above 1.3625v and thereby damaging my CPU. So basically if i go to 1.4v i'm looking at a fried chip in 2012 if i'm lucky? Damn.
Hmm, thought it could go to 1.4v without worries.

Edit, i think i go 3.6ghz now, and when needed i go to 4.0 ghz to increase the lifespan
At a point i think i throttled the CPU volt up at 1.3625v (the limit) but never got into windows, did this damage my CPU in anyway? I would like this chip to hold for ATLEAST 3 years! was looking at 4-5 years. hm.

Just like how you need 1.6V in the bios to get 4GHz on the Q6600.
 
You can go ahead and do it if you're not gonna keep the cpu for more than 3 years.

 
I guess.  
 
well, currently i am not in the need for those extra mhz so i will keep it at 3.5mhz with a bit of tweaking in the voltage. I'm hoping it will last 4 years.
 
Thanks!

Can I ask, what it's not doing for you at 3.5GHz that 4GHz will?
 
It's good to get as many years out of components as possible, but if keeping your 3.5GHz OC stable requires 1.3625V, then I wouldn't hope for 4-5 years, somehow.  Even if the processor is cooled well enougth, putting more volts through it than it can handle will either kill it outright (as per badge) or severely shorten the lifespan (as per Evilonigiri).
 
By all means, slap on 1000+ sun block and crank up the volts if you're so inclined, but above 1.4V your processor lifespan could very well be measured in seconds (very unfortunate) to probably only months.
 
Try and keep the volts as low as possible for longevity, but high enough for stability.  I'd be happy getting 2-3 years at 3.5GHz.

Seabreeze, you have a different viewpoint from others. While you may not need the extra speed, others who does encoding, photoshop, etc. needs the extra speed to save time. A difference of 500MHz is pretty significant, and it will be noticeable in cpu intensive applications.
 
Of course there are others who just want to see how far they can push their system. They are known as OCing enthusiasts, with really no practical use of the extra speed. This is pretty much like any hobby, so they don't need any practical reason to OC.
 
Some intensive cpu game like Supreme Commander will require the extra speed for it to be playable. I had to OC my Q6600 from stock 2.6GHz to 3.15GHz just to be able to play the game a little smoother, but the game still slows down tons in the later part.
 
I doubt 1.4V will shorten the cpu life to months, what makes you say this? The E8400 are quite new, so there isn't any people with OCed E8400 dying on them due to high voltage.
