Maximum Voltage of moden cpu silicone?

post #1 of 14
Thread Starter 
Question as seen in title.

Do we know appeoximatly how much voltage the silicone structure in modren cpus can operate at maximum?

I am talking about material designs here max voltages they are rated to do.

The manufacture may state a max voltage, but that doesn't mean every CPU of that SKU can handle that much voltage. They may degrade very quickly or just out right not survive .

On the other hand, some CPU's may handle and even exceed the maximum voltage for many years and never degrade.

The answer is: There is now correct answer.

I generally 24/7 way above this safe voltage for the clocks i need.

Ivy was 1.65 24/7. This 4790k thouggh isnt liking more than 1.5v. Looking like a 1.47v 24/7 for 4900mhz. Sure makes me miss my old 3770k. Took a beating and always asked for more.

They always last until i upgrade every 2yrs~.

Also taking out transitor max voltage and heat generated by the cpu

I've been running my 2500K at 1.52v (load) for just over 1.5 years now, and that was purchased uses. So who knows how it was treated before then. No degradation or issues yet. *knocks on wood*

But I do agree, if your upgrading every 2 years or less, It doesn't really matter anyways. The worse that could happen is it degrades and you add voltage / reduce clocks, or it outright dies and you just get another CPU.

I see where you guys are comming from.

But what I wanted to know is how much voltage the silicone in the cpu can handle.
For exmaple if heat wasn't a plorbem We know cpus can run at 2-2.1V using amd fx as a example.

So if we are subzero and nothing goes wrong. Temps good and motherboard good.
I was just woundering how much would the max voltage for modren cpus will be.
Using our knowledge on slicone materials and proffesional data on cpu construticon to answer this question.

I know I probally will never get the answer I will be looking for, as I don't think much guys know about this kind of stuff.
I think transitors are made out of slicione and every transitor made has a maximum operating voltage.

CPUs are made out of allot of transitors and I am curious for an approximate maximum voltage modern cpu are rated to do
Not overclocked voltage of the max voltage the slicone should be able to handle but stock voltages

That's really an impossible question to answer. Assuming you removed all the limiting factors (cooling, motherboard, power, IMC etc) and you could just run the voltage (and clock speed ) as high as you wanted to, you still wouldn't have a 100% clear answer on how much voltage it could take.

You could test 10 CPU's, keep pushing them faster and with more voltage until it died. However, you still wouldn't have a clear answer because some of them will handle the voltage just fine, and others will die very quickly. You could find an average, but you would have to have a larger sample size to have anything worth validating.

There really is not set maximum voltage, because it's just not possible to determine. There are way too many factors to come to a solid conclusion.

Theres a point where tempertuares are safe and operating conditons are also safe and normall.

But if we push votlages to a certain point the transitor will instantly die. Due to the slicione used inside, it has a maximum rated operating voltage.

Example, the transitor is designed to run at 100V.
Its maximum safe operating voltage is 50V
Before we even go past 50V the trasntitor is already imposible to cool wihout extreme cooling.

With extreme cooling and assuming tempertuares also stay in safe ranges.
The transitor will instantly die once we hit 100V or higher due to the slicone used inside.

Doesn't really work like that...

Cars are made out of steel... what's the maximum speed of a car?


CPUs are complex... probably more complex that a car. There are billions of components and quite a few variables to consider (manufacturering process, design, transistor structure, layout, temperature, etc). There's absolutely no way to answer your question because it's too abstract.

You can't really kill a CPU instantly without physically modifying the motherboard or pins....
Once again...
