Intel to launch 6 core Coffee Lake-S CPUs & Z370 chipset 5 October 2017

Starting to feel like by the time that these are properly available then it's just going to be worth waiting till next year to upgrade.

That was not said by me. It's not the first time his videos have been disproved.
He had another where the 580 was beating the 1060 by quite a margin. He quickly took that down once he got called out on it.

Besides, were talking about windows performance we don't need another bloody ryzen thread.

I do not disagree with you mate. But read numerous times this comments abouts Joker's videos.

---------------------
Back into the subject. I do not wonder if many face issues with cooling the top of the 8xxx series. I have in front of me a 8600K which just delided for a friend of mine, and intel has cheapen out on the paste also. There are big gaps, having the silicon touching directly the cap.

Saying that, the Asus Z370I, is very kute board, and better packed than some of the bigger Z370 sibligns or the X370 CH6. (yes WIFI)

That does look quite poor. I thought mine was bad!

I noticed the black adhesive on mine was excessive. I also put nail varnish over the contacts on the substrate.

Wow that's terrible, whats your temps now @gavinh87 ?

Under full avx load 5.0ghz 1.36v with h100iv2 my max temps are around 75c (using OCCT with avx enabled)
Before the delid, I would hit the thermal throttle limit.

Thats twice as much TIM the 8600K had!!!!!!!!

Yeah, the machine that puts this TIM/adhesive on is very inconsistent.

Given Intel's money pinching, I wouldn't be surprised if is manually plased with a relid kit, and someone getting paid $20 per month.

Any idea on Realbench stress test temps? I've not clocked mine to the full fat 5GHz yet (I know, I know...). It's such a huge boost up from my FX8350 that I decided to run it on MCE alone for a while. Then, once I'm more used to the feel of the speed I get another free perceived perf bump to 5GHz, albeit a small one.

At 4.7 all core with auto volts/MCE (about 1.38) I'm seeing mostly 69oC on the stress test / up to 16GB RAM / 15 mins. Given the relatively high voltage on auto/MCE I'm wondering whether I'll see any actual real world heat increase at 5GHz with - hopefully - similar volts.

PS: Not sure you'll remember but me buying the 8700k is your fault.

I spent the year waiting on 1800x until I read your posts and realised this would suit me better. Very pleased so far!

I hope you don't blame me if anything drastic happens in a few years and the 8700k is dead!

Realbench gets it to a toasty 82, but I put that down to it using the GPU aswell and having that heat dumped into the already restricted airflow in my case isn't helping.
In bf1/forza 7 temps sit at around 60c @ 5ghz.

Meh, I don't get that argument personally (I know you were being fatuous btw). My FX platform was long 'dead' too, but it didn't matter until it felt slow and I wanted to upgrade; at which point I wanted a new mobo/chipset/features anyway, so...

My temps sound OK then, I'm glad I paid a small amount extra for the delid. Cheers.

Supa Koopa · 25 Oct 2017 at 14:39

Well it looks like a delid is a very good idea. Mine is standard and under a custom loop of a 480 rad and 240 rad both running push/pull fans my temps are crazy with a standard chip. I bought a retail one for the extra warranty, but I can't run prime95 small fft's as this shoots the temps in to the 90's at 5ghz.

I'm going to pick up some new thermal grease and try re-seating it, as I might have made a mess of it but I wouldn't think it would be that much of a change.

I'm also getting seem to be getting quite a lot of voltage droop. I have a Hero board and I've set the adaptive voltage to 1.395v which gives me a stable 5ghz in realbench but the drop is down to 1.36v at best under load, it drops to 1.328 - 1.344 on occasion. So it appears I only need a constant 1.360v for it to be stable at 5ghz. Do I just keep upping LLC until I get a more constant voltage which will then let me drop the vcore? Or am I looking at it the wrong way? I'm currently set at LLC5. To be honest, I've always been a bit lazy previously when it came to overclocking and just let the board do it so I'm a bit of a newbie really, but if I try that it wants to push 1.45v through it as a minimum, on one occasion I looked at the vcore on auto at 5ghz and on entering windows it was even higher at about 1.46-49. I gave up on that idea and changed it in the bios immediately.

I'm happy with the improvement, it's just a shame the temps are so high and I'm a bit scared of delidding it myself now.

Update the bios to latest one. All ASUS Z370 boards suffer from Vdroop ignoring completely the LLC settings also.
As for temps, I am not surprised mate. Check above my pictures from the 8600K. There is barely any TIM over the silicon.

Actually his post had my quite surprised, the hero board is one of the few Asus boards that did not suffer from voltage droop. With my llc set to auto I see no droop.

Supa Koopa · 25 Oct 2017 at 15:23

@Panos - I tried the latest bios and unfortunately it didn't make a difference. It's also such a shame that the tim is that bad on them and was shocked when I saw your picture. I'd delid it myself but they don't seem to sell the tools to do it anymore.

@Gavin - As daft as it sounds I've not actually tried LLC auto since I went to manually overclocking and the new bios, so I'll try it again later.

Next daft question, if I set the vcore to manual rather than adaptive, will it always stay at that voltage? I tried setting it to 1.35 and it never seemed to drop even when the cores under clocked themselves during idle. This seems to just generate heat for the sake of it. Like I said, I'm a bit of a newbie now.

Mate your are at Wakefield. I work here. We can meet tomorrow and lent you the delid tool. But I do not have re-lid tool. I used the Asus plastic bracket and the socket to seal the 8600K putting glue on the 2 corners.

Supa Koopa · 25 Oct 2017 at 15:32

That's really nice of you.

Which tool do you have, is it the nice one that you wind in or the other ones that go in a vice?

Might need to go PM with this.

is a nice one no worries

but you haven't configured your trust for PM.

Oh, now I feel like my granddad and don't know what I'm doing. I think I've fixed it.

danny77 · 25 Oct 2017 at 17:54

I wouldn't worry about not having a re lid tool, most people don't bother gluing or using sealant and just use the retention bracket to hold heat spreader in place.
