Delidding a Core i7 6700K

[BoredErica]

I don't think delidding would be enough to go one entire multiplier higher than one can currently get to though. Maybe half a multiplier as a guess. This is not a totally useless observation especially with Skylake, since base clock overclocking is really a thing now.

Explain mr 4 post man. You do realise i speak from experience I hope.

But nobody has any data about temperature vs. lifespan.

After your answer one area where heat-dissipating plays a big role popped up in my mind: Servers.

I would guess the big server farms have that data and sometimes they share it. I think last month one of the big ones shared their data on life expectancy of the different SSD´s they used.

And I would guess the Coin Mining companies have that data, too.

 

In my company we actually tested that to some point. We assembled a server for a customer and needed to add another CPU. A week before that I had a discussion with my boss about thermal compounds and he actually ordered a better brand than we usually use.

At the stress testing the CPU we installed had about 10°C less temperature than the pre-installed CPU. ( I don´t remember the OEM, we sell HP, DELL, Lenovo and so on)

There was no delid, that is just the TIM between the CPU and the Cooler making the difference. If you add a minmum of 3°C a delid could bring to that.

That is an huge amount of thermal energy that does not need to be cooled.

 

Sure its not about regular users anymore, but the influence of the right TIM is visible.

 

In conclusion I would say, if you exchange all the TIM in a laptop including a delid you would get more performance out of it. Less power consumption, less CPU throttling and so on.

Lower temperatures do not change power draw, and the thermal energy emitted by the component remains the same. The only difference here is that the cooling efficiency is better due to the higher quality TIM. CPU throttling only occurs if the CPU overheats. If it doesn't overheat, no thermal throttling.

They do, see here Effect of Temperature on Power-Consumption with the i7-2600K

I will accept that correction.

[Opferlamm113]

With those physics in mind and some extra ones I think it should be possible to show that the 3° Kelvin extra cooling from the delid using the stock cooler are actually very good. Sadly my Basic Physics Course from university is not sufficient enough to prove it.

oooo you sure got me with the 4 whole posts. Now lets make it 5.

 

Have you actually delidded a 6700k? Have you actually put it in a system that has a cooling setup significantly more substantial than just an aio? And have you actually pushed one past the voltage of 1.45v that is generally considered "safe"?

[Colonel_Gerdauf]

I have been wondering about the video contradicting the results found everywhere else. Even with IC Diamond being a subpar option for TIM, the "just a few degrees" Celsius delta that @LinusTech is reporting makes no sense.

LOL

Guy used the D14 box to cover things up to increase temperatures artificially. I briefly considered doing a test of that on my own, but I never thought of doing that. I commend the guy for the creative use of a cardboard box.

I've delidded over 100 6700Ks, and I've never seen anything less than a 10C drop across the cores (closer to 15C when pushing the voltage.)

 

If you're going to delid, a liquid metal like CLU is a must and you need to clean as much of Intel's sealant off as you can to narrow the gap between the die and the IHS.

what do you do that let you delid so many?

He runs a website that sells binned chips, and offers delidding service. Highly recommend it. $50 and you get a well done delid, you get a reseal, and you get the risk associated with delidding off your shoulders.

No my 4670K, at 1.412V. 

 

But that's my point, you have to use something more than regular cooling to reap the benefits. Hence the vast majority of people (note the word "RARELY") won't substantially increase their overclock by delidding. Since the thermals, while high, are generally not the bottleneck. 1,3V, on the stock TIM, with a AIO is easily do-able. 

 

Linus is just over-exaggerating and is leaving straw all over the place...

You shouldn't make blanket statements that are false. You are correct in that the only people who really should be delidding their processors are those with the means to take advantage of the increased voltage headroom and are willing to accept the risks associated with delidding.

 

And yes, Linus is pandering to his target audience.

Wasn't a blanket statement, because I carefully added those caveats. And it wasn't false, you just misunderstood.

You should head over to Overclock.net or visit some events where they use exotic cooling, you might learn a few things instead of throwing out ignorance as fact.

Well, my 6700K isn´t.

That will be because it isn't Haswell-E... it's a skylake CPU...

Haswell-E doesn't need a delid, it uses a soldered die to IHS.

He retracted his statement upon presented with sufficient evidence. Why are you berating him for doing something totally normal.

Not everyone knows everything, and even the most informed persons can make a bad remark. 

 

The only thing that would've been deplorable, was if he had still continued or make some cheap remark to debunk it.

 

And it's even more ironic when it's coming from you, the biggest AMD FX apologist on the forum. Talk about being wilfully ignorant.

Here's a sweet tool for delidding if you're afraid of using a wise :

 

Can be bought at: https://www.entersetup.com/

Edited April 25, 2016 by Crabcake
updated video url and shop link as the guy decided to start selling them due to high demand.

[Majestic]

Still waiting for that follow-up, or correction @LinusTech

[Majestic]

Bump

[Majestic]

Still no reaction, bumping it again. You can't just put up false information and leave it untouched.

Linus got a delidding tool in the mail, he can now show how to make a proper delid.

Any idea what tool he got, and when he's going to use it?
