7700K overclocking

[Demonking]

So I have the 7700K overclocked to 4.8ghz on 1.4volts with a Kraken X40 I want to know is that voltage too high and if so where can I start to put it at.

[grimreeper132]

two main questions

what temps are you getting??? if above about 80C under load then lower voltage

are you happy at running it at that voltage??? I think from memory the voltage that it's not recommended to go over when overclocking it 1.45 or 1.5V but I could be wrong here

Idle around 35c underload around 80c

I usually look at overclocking guides for this information as it is dependent on the cpu. I'm not familiar with safe voltages for the 7700k but I'm sure there are plenty of guides out there that discuss this.

You're fine at that voltage.  That doesn't mean you shouldn't try to lower the voltage if you can.

 

Consider delidding as it really wakes these 7700k CPUs up.

that load temps perfectly fine, I personally like temps to be under 80C, but that works fine and there is no issues there so that anit a problem. again the point falls to are you happy with those temps and voltages, if both are yes, then there is no issues   (I know this is a cliche and a unclear answer, but this is the only answer I can give, which i am happy to give)

think it's 1.45V for intel but I could be wrong

far as I remember delidding doesn't add much performance at all as the LTT video showed when linus did it, so there's no point doing that really

That video is one of the biggest jokes on LTT.  He's been asked countless times to redo it correctly, but he refuses to do so.

 

With that said, every 7700k owner who delids observes a 15c to 25c + temp reduction along with much higher overclocks.

 

I really wish that video would die, but it keeps making it's way back.

Safety voltages has to do with the cpu. You can't just say it's one set voltage for all products form a company. It is silicon specific so you need to base it on the generation/architecture and preferably the cpu. That's why I said it would be safer to look at overclocking guides as they generally talk about this.

that is true yes, just looking into it other people are suggesting 1.4V being the max so there you go.

the thing is I have heard shit about it from both sides saying there is a difference and there isn't so I am standing by with don't do it, as it causes more issues than it solves, until I see an repeated test to prove it does work

Some things you just have to see first hand and I can appreciate that. 

 

I can tell you with certainty that Linus' delid was the poorest I've ever seen.  He failed to remove any of the factory adhesive, which is the biggest source of the problem.  Everyone thinks it's the factory TIM that causes the issue, but it's the excessive adhesive, which prevents the IHS from making solid contact with the die.  Lack of pressure.  It's that simple.  If you don't clean up the substrate and IHS, you'll have the exact same problem when you put it back together with fresh TIM.  

 

Anyways, here's a 8 hours RealBench stress at 5.3 GHz with an average voltage of 1.439v over the duration of test.  You won't ever see those kinds of max temps without delidding.

Also, just for fun, earlier today I ran another delidded 7700k on a cheap old z170 motherboard using a stock Intel cooler that came with and i3 6100.  It didn't do to bad if I do say so myself.

Does me repeatedly doing it, and getting good results count? I understand the fear behind delidding, as it's basically taking a vice/blade to your $300+ CPU for better thermals (and potentially better overclocking headroom) but it does work. You can mitigate this risk by using a delid tool and by taking proper precautions during the delid. Cover any gold contacts near the bare die with tape or clear coat nail polish, and use a very thin layer of paste (we prefer liquid metals such as CLU and conductonaut for the best possible results, but use whatever you like). 

 

If you want to see my first delid, I have it on this forum: 

If a big dummy like myself can do it, anyone can.

I am too poor to be risking killing an $320 CPU

Core 2 was about 84C
