I de-lidded my i5-3750k with incredible results. I've only been running my i7-4790k at stock so far, and honestly haven't even paid attention to temps!

So I'm curious if it's worth it... anyone here with experience delidding the 4790k?
 
There is plenty of people that do/did it... Results, just like the 3750K, vary.

There isn't a point in delidding unless you are temperature limited and not voltage limited.

I've seen a few threads with results of delidding the G3258 and 4770k, but can't find any before/after on the 4790k. With the 4.4 Turbo, I'm almost fine not overclocking. Wait, did I just say that???
 
I have no idea, if temps are in order and you are happy, why you would risk it and void your warranty....

Because I can.

I do it because I can.
I can because I want to,
I want to because you said I couldn't

Honestly, I haven't even tried to overclock the chip yet... and after the 3750k experience I'm looking for some empirical results with a 4790k.
 
Ok, you've had over an hour to check your current temps. What are they?

If your temps are already good at 4.4 GHz, I wouldn't bother. At most, OC'ing will give you another 500MHz, if your lucky. Temps on a 24/7 safe 4.8-4.9 OC won't be but so different than 4.4

edit: Feel I need to add I am a believer in doing something just because "you can". But like I said, temps on a 24/7 safe OC shouldn't be that different between 4.4 and 4.9 GHz. 4.4 GHz is going to be on the warm side as it is.
 
LOLOLOL... never said you couldn't, just that you SHOULDN'T. ;)

Have you tried googling, "delid 4790K" and search for results (until someone here chimes in, there is something for you to dig into..:))?

Good choice of keywords, first hit is a goldmine

10c drop delidded. Stable at 4.9 with med-high voltages. That's huge.

After I finish a few other other projects, I'll be playing :clap:

:toast:

Mainly Crunching... more PPD. Otherwise, I agree, the chip is a beast on it's own.
 
check my edit @Sasqui

Yes, I'm getting ahead of myself... I don't even have a baseline. Question was more out of curiosity after stumbling on a thread about delidding a G3258. I just swapped/sold and unmodified G3258 (quite happy at 4.5) with the 4790k
 
i have delidded several chips on several computers, from friends and also computers that i use, not all of them are being overclocked, but the ones i have done have shown excellent temps, minimal temp drop of 12C and with a 4770K that showed up incredible 25C drops... on Stock and like 20 on OC... i really suspect several things about that processor, she got it from a provider well known for selling OEM processors...

Unlocked processors:
3570K, 3 units, this bastard gives excellent numbers when OC'd, great clocks and also most of their great overclocks are with stock voltages,
4770K, 2 units,
4590K, just 1...
G3258, just one so far..


Locked processors :
4460, just one.
4590, 3 units... they were in a really hot place, no money for a better cooler... so delid was another method for lowering temps...
4770, just one,
3770, 4 units, including mine, which was my first delid, then another on work, and 2 from 2 friends,

Regards,

Wow... I totally agree about the 3570k, see my specs ;) Curiously, with vs. without the IHS (naked), it didn't make much difference.

I still need a baseline for the 4790k, overclocking the OEM, which I haven't done yet. Too many other projects going on at home.

never ran any chip naked,

4.4 for a 4790K is a super cool sweet spot.. 4 ,5 is also cool.. once you start going much over that the temps go up along with the needed volts..

trog
 
Don't forget that 4.4 is the stock turbo boost speed for the 4790k... it's an ANIMAL! :) http://ark.intel.com/products/80807/Intel-Core-i7-4790K-Processor-8M-Cache-up-to-4_40-GHz

mine will only boost to 4.4 with a single thread application running.. two threads it boosts to 4.3 and more than two threads it only boosts to 4.2.. running a 44 x multiplyer gives 4.4 on all 8 threads.. it is worth doing and chip will do it at something very close to stock voltages..

i run mine 24/7 at 4,5 gig.. the chip does this very easily.. 4.6 needs more volts and 4.7 needs a lot more volts.. :)

4.8 gets silly.. he he

trog
 
i wouldn't delid it.
You void the warranty..then you'll wanna lap it next ...
at which point if/when it dies you will eat it.
They don't taste very good to me.
Oh..here's one more thing:The 2 newer generation of chips fail at a higher rate than all previous generations.
I have personally have had..ok..2 4790Ks and 1 4770K fail..and someone else had one fail and I RMA'd it for them or something.
That's all during daily use, too.
Sure,I've killed chips before..giving them 1.9v.. but these things just fail with regular settings.
Other people are having similar results.
PS: The newest chips have even smaller/thinner dies.
Look what happens when you go to wipe the TIM off of the die:

Interesting... that sounds something like the turbo scheme used on mobile chips. I'll be checking that out, thanks.
 
delid method?
its almost imposible to broke CPU Die when you delid with a razor blade lad... also delid is up to ivybridge proceessors... sandies and older are soldered... delid is not a shinny option there... also is pretty complicated for getting no more that 1C drop with so much luck .. otherwise could shown worst temps...

under normal or stock settings that processor its capable of those speeds lad... unless it gets to hot and starts throttling....

Yes, I posted the same link previously. What's the best SW to see all the core speeds and temps... ?
