8700k 4.8ghz stable...

Still have to tweak the fan settings etc. but so far I've managed to get 4.8ghz at 1.31vcore and hitting 75C ish in p95. I'm not keen on going any hotter and I don't want the fans louder so is it worth staying where I am, or delidding and pushing to 5ghz +?

I'll post some screens of my OC settings when I'm home.

Cheers.
 
Mine is at 4.8ghz and I've had it at 5.1ghz but it needed more volts and was pushing 82 degree's at full long load. 4.8 temps are well under control and other than benchmarks the extra 2/300 mhz isn't noticed. Enjoy the hex core loveliness
 
changing a few settings, shortening the lifespan of your cpu, higher temps, louder fans for 200mhz which is zero difference from 4.8 doing day to day tasks isn't really an achievement :)

I've dropped my 5.1ghz delidded down to 4.8 just for temps and noise tbh.
1.28v at 4.8ghz give a maximum of 65c under avx loads. The same cooler etc gives me 85c - 90c for 5.1ghz at 1.37v
Not worth it for 24/7 usage. Plus lowering the core clock has allowed me to run memory at 4000mhz even on a 4 dimm board.
 
As above if 4.8ghz is enough then leave it. 75c is fine and you will likely not notice anything above 4.8ghz with regards to tasks and games.

Although a delid is very straight forward with Z370, if your wanting the absolute maximum from the chip. No components to accidentally knock off like on X299.

Delidded mine although i don't have the best chip going. 1.4v @ 5.1ghz. Refuses to do anything above that.

Just got my 8700k and managed to do a quick dirty 4.7ghz on all cores at 1.25-Volts.
So far stable in windows and did a quick stability test with AIDA 64. Will do some proper testing another time as putting together my rig was a headache lol. Delided it anyway and max temp i saw when stress testing for 20 mins was 50 degrees

Wow, you hit the lotto well there. I'm hitting 65-75 but I'm having to use 1.31vcore to keep 4.8 stable in p95

Yea i'm unsure what's going on because i set my voltage to 1.25 thinking that's a good starting point not realising it should have been 1.35 that der8auer said to set it to for 5ghz overclock. I thought hey start there and work my way up. Now ive realised i set it slightly low but it's stable i'm like what the heck? There's probably a wall some where anyways haha. I bet as soon as i try 5Ghz ill have to bump it to 1.3x volts. But the delid and liquid metal seems to have done a great job with temps.
 
The most taxing thing I'll ever currently do on my CoffeeLake cpu is a long handbrake 4k encode. Running prime and other apps just to stress the cpu seems pointless to me thesedays. Gaming never really stresses the cpu imo so in my book if my rig encodes and games flawlessly I'll go as high as possible, but not a far as silly volts and temps.

I think it would be wise to leave hwinfo running to check to WHEA errors if you don't want to run stress tests. It could help with troubleshooting any errors you may get down that road.
Just my thoughts.
 
Seems like several of you have vastly different temps to mine, even when delidded... I do have plenty of water cooling But I don’t really see mine stray much past 70c and that’s running 5.1 or 5.3 (1.35-1.4v) if I really want to (Not 24/7). Memory at 4,133 also.

Delid is likely to shave 15c off, if you are comfortable.

1.37v gives about 85c under aida 64 using avx on a h100iv2, delidded.
 
As everyone says comes down to the fact if you want it to have it for the fake of having it or for performance. In reality any gain will be minimal in the real world. Having said that I'm running 5 Ghz
