8700K temps in Clevo P7xTM1's

This was using just a repaste, to change ICD7 for Kryonot. The supplier had already did a delid. (did not check it yet)


After reinspecting the delid and redoing it and lapping the IHS and getting the dried up super glue off and doing it right.


I have another system, not the same system but these temps are in the 95C+ range at stock with ICD7.

The bench I used was simply XTU Benchmarking, 2350-2375 on averages.

Anyone else wish to share thier experiences ?

I personally think you have to take note of a few facts.
1) the 8700K is even cheaper built then the 7700, it's silicon is so thin, I literally was afraid I would break it.
2) the temps with 6 cores is crazy, and without better mod support, the power draw is crazy. XTU refuses to work properly yet in this series P7xTM1's
3) undervolts do not stick, but with lower temps the voltage seems to stick around 1.35v area.
4) it throttles thermally, power limit throttle and current limit throttle too.
5) no matter what or how bad the testing semss, these 8700K kick some serious ace ! (like minimum +25% performance on 7700K)

@Tb5... this is your CPU BTW.

 

1.35V is too high for stock. Even in Windows 7, it is only set to 1.25V. Can you try static voltage? Try using between 1.08-1.1V for stock frequency. Where are you undervolting, is it via bios or the CCC? If it does not stick, you may need to have TS on autostart.

 

XTU settings do not stick. I also have witnessed the bios settings not sticking either. It acts a bit funny. Keep in mind anyone reading this, that's not insanely crazy enthusiast, that this laptop and cpu is actually still amazing, just not as perfected as say what we have with the 6700K after two years of using it.

I tried static, but it switched right back to adaptive. I had set 1.2 and it looked like it would keep that (tried lower before that) but it reverted as well.

 

Oh, it seems the only option is to have throttlestop in startup to correctly apply the voltage.

 

Hello, i just bough this awesome Laptop P775TM1-G with the fresh new 8700K

i'm not very happy with the management App Clevo Control Center, the fan run so hurry, even when is idle, the temp going high for nothing, and i'm a very newby in the windows world (was mac addict since few month with the new **** of 3K€ who already has been on start)

i seek all this forum to found a solution (Obsidian, Premamod,...) but without real answer

what can i do to make it better?
thank you

 

Fans should be almost silent in idle. Is ur system overclocked? Run cpuz to see it should downclock to around 900mhz in idle, around no more than 40c with fans barely audible
What temp you reading in hwmonitor?

 

You're the first person on this forum which I've seen who doesn't flat out lie. Thank you for that mate.

I know how to cooling of the P870tm which is basicially the same as previous generation with extra added heatsink without a fan (yeah, idk either) and a little extra added heatpipe. I was wondering what they tried to do in the P7xx series, so could you maybe add a picture of the cooling system?

 

I take it you mean the package was super thin rather than the silicon itself being particularly thinner than normal?

 

They didn't bother to change the cooling system at all

At least in the 870 they tried something , altough failed miserably.

EDIT: Nevermind, they made it even worse, they removed the 4th heatpipe

 

Doesn't the 2nd temps look good?

 

They basically deunifyed the cooling system, which manny said what helped contribute to thermal problems with dm3. From my testing of stock system it is quite capable of handling the cpu with undervolt. If it is delidded you be very cool and be able to even overclock. It is gpu 1080 where the system seems to struggle. Jury still out whether can tame it but imo 1060 or 1070 no worries

 

And what about p751 with 1070, struggles like 775 with 1080?

 

No idea. Better read up on 751 user thread for user experiences

 

My 751 does really well with temps actually. Been messing around with it and was doing pretty well in the temps department. That was stock though. Gotta relearn my overclocking from the ground up again.

EDIT: Should add that I have the 1070, 8700k, unlocked bios and delid.

 

My unit currently idles at:

CPU: 42~45°C
GPU: 44°C

CPU: Delidded
Ambient temperature: 22.5°C
Laptop Status: Flat on granite table

I'll have to do more tests later. I'm still figuring out some tweaks, and I'm also installing all my software.

 

@Papusan , here's some power and temp readings of the 8700k @4.7Ghz..Room temp is at 27C, fans on overclock profile

CB11.5

TSBench 1024M

 

I had to have a delid and lapped the IHS and used Liquid Metal for pasting, to lower the temps by 30C

 

I did a quick 3DMark test.

My wife might buy me a system like this for Xmas any one know how can noise is

 

If you game, it’ll always be noisy.

 

Any idea how much more then a Alienware 17r4 gtx 1080

 

I've never owned an AW 17 R4, but going by experience, it's not as noisy as my old AW 15 R3.

I just don't think there are good laptops that would be silent when temps go up to 70+ °C while using it.

EDIT: If only there were fan options for laptops like Noctua, Scythe, or be quiet!. I wouldn't mind the noise as long as I get better fans.

 

could you teach about what we are talking? i so new in that world, thanks

 

Delid = To remove the integrated heatspreader (metal cap) on the CPU.

Liquid metal = To replace the paste that intel uses to connect the die to the heatspreader. You have to be careful as liquid metal is conductive and eats aluminium (the heatspreader is nickel plated copper so fine).

Doing the above does result in much lower temperatures.

 

it's become pretty much mandatory to have this with 8700K if you keep like 4.5-4.7Ghz

 

I'm surprised they have not tried to reduce the z height of the IHS and redesigned the fitting to be as close a possible.

 

*Keeping a VERY close eye on this thread as I have a 8700K and Dual 1080's coming in my system...*

 

There are some gimmicks out there, like copper IHS's you can buy on ebay and from bitspower, but in testing them, they do not make proper contact or improve anything. I had planned to do a whole post showing them indetail but it made such poor contact I was not going to advertise it with pictures and give someone the wrong impression or the idea to try it themselves. It just didn't work out well.

The stock IHS still the best. I guess if these aftermarket IHS were as good as we hoped we would have seen competitive markets for them and they would have stayed around and been a thing.

 

The 8700K is not a fun CPU to delid, it's slightly fragile, you can tell when handling it that its more fragile then a 7700K is.
The temps and throttling is three fold worse too. It requires some serious time and effort to get it perfect, whereas I found Skylake was like set and forget and thats all. Kabylake was a minimal time investment needing to specifically undervolt it and your good to go, 8700K is like manditory you delid - BUT it's more risky, IMO. Not a 100% exact fit like Kabylake and Skylake were, it's like 1/10th a mm wider or thicker if I had to describe it.

It throttles from power(voltage), throttles from temps, throttles from current(Amp/watts set..), it's like hotter and more thirsty as well, so this is a CPU that is a pretty big stretch to have in a laptop. Bigger stretch then having the 6700K/7700K was by far. But the performance is insane, again - if it throttles though, then its a pain in the arse...

I recommend no one wasting thier time with a OS on a HDD with this CPU. It's like putting a Ferrari specially tuned engine on a old stationwagon from the 70's, it just won;t handle well and be a waste of performance.

 

I'm not even sure you did it the right way. But I, @Stress Tech and @Mr. Fox got good results with Bitspower IHS. Rememeber select the correct one. As they come in 2 variants (thickness).

 

I couldn't find one for kabylake, only skylake, and the knockoffs were horrible. The skylake was better when I just lapped the original IHS to the copper itself.

 

Hi @woodzstack
IMHO Every IHS lid is different to the other lid. I have even seen and used 2x Sky Lake BitsPower IHS lid (both exactly the same model and I label each one) and each one will perform different from the other slightly. I have even used the same "one" Sky Lake BitsPower IHS lid 4-6 (I have missed count) on the same CPU, and every prep work is different by either 1-3 degrees even at the same room temperature. So, I thought I must be doing something wrong... So I even got a friend to try some of my IHS lid collections on his P870KM1-G and he found the same thing using the same Sky Lake BitsPower IHS. I have even had a material analysis from a CNC precision factory even make an analysis on the Sky Lake BitsPower IHS lid. And I can tell you; each one has a different story due to its electroplating nickel finish and the cleaning solution (oils) used just before the electroplating procedure.

The moral of the story is: that every BitsPower IHS lid is different from the other, especially if you do not lap the surface. Every prep work will give you a different reading even if you use the same IHS lid over and over again. It's all about flat contact, thermal compound used, thermal compound prep work, silicon lottery on the finished IHS lids, or how the lid was created; either by casting or CNC milling and finally the material of the IHS lid. Silver .925 to .999 or copper alloys ranging from C80000 to C99999 (C80100 to C81200 being the best for thermal conductivity).

By the way; I went with @Papusan and I tried lapping my Sky Lake BitsPower IHS lid and I found a temperature improvement. I have also used .925 silver IHS lid's on my CPU and I have found a 1-2c improvement too. Please see this thread:
http://forum.notebookreview.com/threads/silver-7700k-ihs-prototype-testing.809218/

IMHO I really think the thicker (more body mass) of a IHS lid, the better it will be able to absorb temperature spikes from the CPU die, just before the heat is delivered to the heat sink for heat dispersion (this also includes on other technical factors too)

And here is some of my IHS lid collection, including the .925 silver lid which I have just took out the other day and cleaned. The blur image on the .925 silver is the reflection of my pear tree. Sorry about the photo quality.

All these lids have been tested except the 3D printed ones which were only used for testing fitting requirements.

From first row, left to right:
1: 3D printed plastic prototype with 1mm extra height (top face),
2: Sky Lake BitsPower shining lapped lid (the finish is horrid due to the moulding procedure when the first .925 lid was casted),
3: Copper CNC machined lid with no 1mm extra height,
4: .925 silver lid after it has been cleaned from liquid metal. The marble effect on the face is a reflection of a tree.

From the second row, left to right:
5: 3D printed plastic prototype with 1mm extra height (bottom face),
6: Original Kaby Lake IHS lid from a 7700K CPU,
7: Original Sky Lake lid from a Pentium G4400 CPU,
8: Original Sandy Bridge IHS lid from a Intel Celeron G530.


Edit: Re-named "Kaby Lake" to "Sky Lake"

 

Thats incredible, thanks for sharing.
Hmm, does give me more to think about.

How did you get a jewelry IHS though. lol

 

Your welcome.
It's a long story bro. Check my thread out here for the full story:

http://forum.notebookreview.com/threads/silver-7700k-ihs-prototype-testing.809218/

Hopefully the new .999 silver IHS lid will be completed soon. I will keep everyone posted via my thread.
Best regards

 

This means you tested it on 6700K (As You lapped the orginal Skylake IHS).

 

yeah but the test I promised was trying to find an alternative that was more reliable then the 7700K stock IHS. For Skylake it was not a big issue to begin with.
I couldn't find the bitspower one for kabylake everytime I checked. Its like they had limited supply and then took them down and not for sale anymore.
The conclusion was the original IHS was better.

This other guy is sporting his own tests and concludes it's a gamble, or that 50grams of pure silver makes upwards 3C better temps in testing. ****, are we testing gold next too ?

 

I never tried the Kaby Lake BitsPower lid. I might get some.

The Sky Lake lakes BitsPower (which is 1mm higher) lid advert normally gets taken down when they run out of stock I think. They do produce better results than the orginal intel IHS lid when used on clevo cpu heat sink from the P870 series (P870TM cpu heatsink not fully confirmed yet) because of the gap or warped heat sinks that senior members spotted.

It will be great if someone can test the BitsPower lid on a desktop PC and compare it to the stock intel lid. Then it will be a more accurate result.

Now I have had the .925 sliver IHS lid for a longtime I can now confirm that the lid gave me a 2c drop on my CPU max temps compared to the Sky Lake BitsPower IHS lid. Hopfully the .999 silver IHS lid (in the works and weighs around 37 gram) will perform better as what Der8auer are stating (which I find is ridiculous). Der8auer .999 silver IHS lids that come only if you purchase a CPU Ultra edition silicon lottery chip from Case Kings CPU range . Der8auer are stating:

"An additional reduction of 8 to 12 °C temperatures can be expected due to the exchange of the business standard Integrated Heatspreader (IHS) with a silver heatspreader. The der8auer Ultra Edition is the absolute apex in all things related to CPU modding and offers the very best overclocking performance.".

I love to see one of these Der8auer IHS lids. I think they are casted not CNC machined.

And gold is a low thermal conductivity compared to Silver. Silver has the highest (any direction) thermal conductivity of any metal. It is also the highest reflecting light metal and the most 2nd best for high electric conductivity. It is a great alloy.

 

The lid on 6700K have never been a problem. The problem is the orginal Kaby Lake lid. If people don't sell or use their 6700K when upgrade to 7700K... Use the lid from Skylake.

I fix it for you "The Kaby lakes Skylake BitsPower (now included Skylake & Kabylake) = (which is 1mm higher) lid.


Orginal 6700K lid vs. Bittspower Skylake lid.

 

Ah I see where I went wrong, it's the Skylake IHS I needed all the time, for some reason, some part me being so by the book at times just didn't think of the obvious. Must be a brain fart !

 

Intel and AMD's IHS is concave. They really need lapping!! BitsPower or the orginal lid... Same ****y.

 

Certainly no point for the same dimensions but if you need an extra 1mm or so extra height then solid metal will do the job best by far

 

right, which was the whole point.

 

I just edited my old post. I changed the "Kaby" to "Sky". I said that the Kaby Lake had the 1mm extra height. This is wrong, sorry. Its the Sky Lake lid that has the extra 1mm height! sorry for the confusion. I probably were half asleep then...

The Sky lake BitsPower lid gave me a 2c drop on max CPU temperatures when on full fans. I had to lap the lid to achieve this effect though.

 

Maybe Edit your post #39 as well Maybe it is time to wake up?

 

@woodzstack , so the voltages don't really stick after all even in the P870TM. Have you tried setting the value of xtu fan table support to 0 in the oem.ini? It seems to have worked for me.

 

where's this file, and what are the rest of your settings ? (in XTU settings ?)

I found the 8700K tricky to play with, but manageable, the thing is it's plenty powerful at stock, kicks a 7700K's butt for sure on the multithread.
I do not feel it was less powerful on single thread - like things were spontaneous as I'd expect.

I do not understand the logic behind the fansetting here though, how did you come to this conclusion or pure accident ?

 

Oh sorry about that, the oem.ini can be found in the clevo hotkey folder installer. It just basically removes the Clevo Cpu/ram OC utility.

I just found it by accident. When I rechecked my voltages, it was set on adaptive in the CCC. Whereas, I was sure I set it to override in the bios. Since we've been removing the cpu/ram oc utility in the P870DM/2/3, might as well give it a try. It just happened that they removed the configuration in the setup.ini and placed it in the oem.ini.

 

Thank you.
