Intel Core i7-7700K Delidded, Reapplied TIM Reduces Temps By 30C

[hat]

That's what happens when you want them to warranty OC. It's not like an extra 200 MHz is going to matter anyway, unless you need the bragging rights. Why would they bother supporting the egoist?

People want chips they can OC, but don't blow up. So that's what we've got. I see no problem in that since I watched it slowly happen over the years, the whole time complaining about those focused on OC. So much so that I don't even put OC in my reviews. Go complain in their faces, not mine. ROFL. I didn't make it this way, they did.

I'm not complaining in your face. I'm not telling you to fix it as if you were an Intel exec. We're merely having a conversation.

I don't know what people take overclocking to be, but when I learned, I, the overclocker, was to be responsible for any damage caused to my system due to risk involved (or my own clumsiness). I have no right to buy a CPU and complain to Intel because it won't reach 5GHz. I'm not saying they should warranty it (unless it's a product made for overclocking), or even support/allow it (although I do think removing the capability from all but the most expensive K/X labeled parts is a dick move). I'm saying they shouldn't be artificially limiting their CPUs by causing them to overheat by using monkey spit as thermal paste, because their processors need to overheat and throttle down so they don't damage themselves during normal operation as you suggested.

I've never seen anything blow up from OC unless the user was either ignorant, careless, or both. As long as you stay within reasonable settings, you should be fine. Nobody should be ramming 2v through a processor or trying to reach LN2 overclocking records with a rusty air cooler. There's no reason to "protect the user from themselves" by artificially limiting their product. If it blows up because you fucked with it, then that's your fault, yeah?

Hey one question...

Doesn't it make more sense to directly mount the cooler on the CPU after removing the IHS, instead of only replacing the TIM under the IHS?
Or isn't there much of a difference?

Thanks!

if you replace the paste with something overkill like the liquid metal stuff, theres no real difference.

otherwise its just a safety issue, crushed dies can and do happen.

I can attest to this. I had an old Duron, i think, that had no heat spreader.
It's really easy to chip the die unless you are super careful in putting the HSF back on. Luckily, I only chipped a corner off mine and it still worked fine.

 

[Mussels]

this reminds me that i need some liquid metal goodness for my 'new' laptop, hits 85C in load... i should fix that

Maybe Intel uses average TIM, not just save money, but to make money. Perhaps they know the lack of solder pushes more enthusiasts towards the E/EP platform with its higher entry prices? Or is it possible it is done to leave a bit of wriggle room between these very much incremental generational releases? You wouldn't want your chip to give you too much performance as to not want the next incremental upgrade, would you? That extra 200Mhz is very enticing...

 

[FireFox]

Not not buy a used dual core processor from craigslist and practice on that. I've heard some people tried it that way.

great points there! nice advise

That is for dumb people.

Actually, there is a difference...

...and it's not a great idea for 99.9999% of users here.

Some massively circular logic happening here.

I think @cadaveca wanted to say that cores, cache and IMC are not made entirely from the same kind of transistors ... and are not equally sensitive to increased current ... and intel's throttling algorithm works solely based on core temps.
Because the trick is to throttle before electron migration even starts to happen, throttling algorithm certainly takes into account the weakest types of transistors in the cpu.
Trouble is that different motherboards apply different voltages to different cpu parts in their XMP implementation (and only cores have sensors).
I agree that having a better TIM under the IHS should be viewed only as "having a better cooling overall" and that cannot in any circumstances be viewed as bad.
However, as an example, it is possible for motherboard manufacturer to set IMC voltage high enough through XMP profile, and assuming delidding is done to overvolt more to be able to overclock more, after you do that you can still be below throttling threshold while at the same time overvolted imc starts electron migrating and it doesn't have temp sensor.
But, yeah, we simply can't say bad TIM is a good solution to get faster throttle response to high currents ... it would be silly.

I have picked up mine a few minutes ago.

Let's see how it performs

This is the worst upgrade i ever have done, in any case i am happy.

This is just a basic OC, Multiplier and voltage increased, the voltage while running Prime95 is 1.392V but when Gaming it's just 1.372V

So if you de-lid you'll have the same clocks at far lower temps.....

Because i have a Water Chiller i don't know if it would be worth to de-lid

Note: if it's true a 30c drop when de-lid maybe i could give it a try.

That is for dumb people.

I dont see any dumb thing on practicing on a maybe $20 cpu vs a $350 7700k.

You won't need a chiller after relidding. Save yourself 1kw, up to you.

Well i already have it, is there and it is running and for sure i will need it when doing some Bench

Seems like 5GHz is the new 4GHz.

I guess so and if you get a good Chip 5.3GHz is the new 4.5GHz

"new" (mine does 5.1 stable, but at voltages i'm not happy with)

Some people aren't born tech geniuses you know.

Some of us might even have motor difficulties. *cough cough*

I agree with you.

Sorry it wasn't my intention to offend anyone.

Shame on me.

I know, I'm just being a butt. Might be slightly intentional.

the 2600k/Z68GD80/NH-D14 combo I had did 5 GHz at voltages and temps I was happy with, if I didn't have it crunching 24/7 (which is why I tuned it back to 4.5 GHz).
