P870DM-G Temperatures. Is this normal?

Hi! I was testing yesterday on my machine with some stress tests and the CPU was easily reaching 95C and at some points getting to a throttling state to reduce the speed and not overheat and shut down. Also the temperature of the PCH diode is pretty much constant 75C even when idle after some time of being ON.

Are these temperatures normal?

Thanks for the advise.

 

Some basic questions:

P870DM on a hard, flat surface where airflow is not restricted and the vents are not blocked? If you try Fn+1, do your fans kick into overdrive and help with cooling? Did you use stock thermal paste in your build or something better like Grizzly Kryonaut, Gelid Extreme, IC Diamond or Coolabarory Liq. Ultra?

In any case, it appears there are some heat dissipation issues with this lappy when running stock BIOS or not tuning with XTU. It seems the i7-6700K has a bit too much voltage and causes some heat issues . Did you purchase from a Prema-mod partner? If so, see if they will send you a Prema based BIOS ( https://biosmods.wordpress.com/partner/)

If not, then use XTU to decrease the CPU voltage to help with the temps.

HTH

 

Yeap, first option would be to install Intel XTU and drop the core voltage by -150mv, if its doesn't stay stable at this, start increasing it in 10mV increments till its stable.

Also what application are you using for stress testing?

 

For the PCH yes this is normal, for the CPU under very heavy work loads you can get some thottling with the 6700K, a perfect paste job with IC diamond quality paste can help this.

Applying a moderate undervolt (well backed off from the instability point, so if -150mv is just where it is stable then go with -80mv) will help if you intend to hammer it.

 

Thanks! I purchased it from Sager, not sure they are a partner or not, they were not able to help me to upgrade the screen so I relayed on Eurocom, so I have BIOS provided by Prema.

It has not caused any problem, I did a stress test and I was really curious about it. Never tested these things before.

 

AIDA64 Extreme. Weird hearing about underclocking when seems the trend is to overclock.

 

Well, the machine was built by you guys, and it is supposed to have the IC diamond paste on it.

Not a big deal, this is just curiosity.

 

Yes, is running on a flat surface, but I have also one of those with air from the bottom with a fan, and that helps, but is too small for this model, I need to get a wider one so the machine does not slip on the sides.

 

Haha, This is actually under volting.
My system is actually running the core clock @ 4.5Ghz with a -70mV under volt and 4.2Ghz Cache with -150mV. Prime95 stable.(this hammers the CPU harder than AIDA64)
All processors are different so yours might work same as mine. But 90% of the 6700k's i have seen can take a -150mV underclock and as @Meaker@Sager suggested, take off another 40-70mV as overhead and to be on the safe side.

 

Besides reading the posts I placed, I would suggest sending a PM to @Phoenix or @Mr. Fox if run into problems or have questions about voltage settings.

Also, you may want to talk to @Jakomo5 for advice regarding a CPU in which the heat issue is still a problem.

Also, bloodhawk is correct in terminology. I corrected my post... it should've said change the voltage, and not mentioned 'underclock'. Sorry for the confusion.

 

Here are the XTU settings to undervolt:

Ahahaha.... so you are underclocking but overclocking at the same time? I have to study this a bit.... does the machines have a failsafe to shutdown if things get bad? or can they get fried???

Thanks! I have reading to do today much appreciated. This overclocking thing is new for me. Usually I do not need to do this and not even dare to do it with the machines at the office.

I understand if I'm using a Prema BIOS I do not need that software??

 

Nope.
@Phoenix has a great tutorial to get people started, after that its pretty much reading and experimenting.

But do not go TOO LOW. (or TOO HIGH) , if you go too low the system might need a CMOS reset, which is a pain in the ass to do.

 

Some people like using it. I don't like it and think it is buggy. Plus, if you have the Prema BIOS it is more or less unnecessary. You can do far more in the BIOS. ThrottleStop is very useful for BIOS tweaking within Windows and @unclewebb has done amazing things with it.

The only thing XTU really has a good use for IMHO is tweaking Base Clock. If there was another way of doing that, it would make XTU irrelevant for this model.

 

Then in that case raising the back by a few CMs will help (say a bottle cap height on the back feet), this helps the fans breathe.

 

Yes. I have that thing like a table with a cushion that goes over my legs, who knows what is the name of that in English, that have two fans blowing up that makes no noise. They help, but is connected to the USB and I have yanked things out of USBs in the past breaking the connector inside so I hate cables.

 

Thanks!!!

 

Lapdesk

 

I find raising the back of a machine helps more than having external fans blowing from the bottom.

 

Agreed. My guess is it helps the efficiency of the heat pipes as gravity is working a little more in favor of the evaporation process. This was definitely true in the case of the x7200

 

I have a question, if we remove those plastic foil/cover covering the mesh on the bottom panel, does it break the warranty?

 

Those settings are for people who don't have the Prema BIOS

If you have the Prema BIOS, then here are the settings for both 4.2 GHz on all cores and 4.4 GHz on all cores (first post in the spoiler):

http://forum.notebookreview.com/threads/clevo-overclockers-lounge.788975/

Note: for the 4.4 GHz settings, if -115mV wasn't stable on your system for any reason, try -80mV if it's stable, if it overheats, then try -90mV, then -100mV until you hit a balance between stability and cooling

 

Really???? And can you fry eggs on top of the keyboard with those settings??? ))))))

Crazy... thanks I'll go to the link and read it.

 

Negative, these are very safe settings, no frying eggs, hot dogs, or anything for that matter

 

Cool! Will have to keep using the stove... do these machines have a fire emergency shut down? I mean if lets say the paste on the CPU is for some reason not that good, and the CPU gets to an unsafe temperature, the machine will turn off?

One more question, you seems to know a lot, do yuo think there will be faster and more cores processor for this machine / Chipset? the 3 years ole Clevo with 6 cores I have is as fast as this new one with 4 cores, the main reason I bought this new one was the speed of the I/O with thunderbolt, Speed of the RAID that with 3000 MBs is killer, and the GPU speed since most of the programs these days are using more the GPU than the CPU, at least the ones I use for photo editing. But for rendering with 3DS MAX, my old laptop is faster sometimes or just there depending on the rendering plugin.

I would love to see a 6 cores CPU for this machine... but that is probably dreaming too much or 40 cores like the ones of my HP Z840

 

Stove is best - or you can use a box lined with tinfoil on a hot, sunny day (if you don't mind waiting several hours).

Yes, the chips have a threshold (sometimes called a TJunction). The system should first throttle to reduce heat, then give you a continuous beep code once you get close to the limit. Once you reach that limit, the system auto-shuts down.

 

any CPU will shutdown or thermal throttle when it reaches 99C so you'd know if something is not right

Secondly, I think there will be a Skylake Refresh come June but I am not sure if it will work in this laptop or what socket it will use. I cannot wait to upgrade as well. Right now, I did upgrade from a stick 6700K to a Silicon Lottery one, even though it's the same CPU, running much cooler allowed me to reach 4.5 GHz easily it is like a CPU upgrade for $500 USD

 

A 6 core processor will any day better than a 4 core one. Specially if it is not more than 5 Years old. Even then in certain things it might beat the 4 core. And 3DS Max always uses more CPU cores, specially if you use Vray or Scanline or Mentalray, unless you are using Vray RT or something like Octane, the GPU is pretty much useless for softwares like Maya, 3DS MAX or Houdini.

 

My main use for these machine is Photo editing, in which many things are still not really multithreaded, there are things that just can't be... so the single core better speed gives me an edge on that. Plus, the memory bandwidth and HDD is a LOT better... MUCH better... the average TIF file I use is about 4 GB in size and using ZIP compression, which is the top. are at last 9000x7000 pixels, 16 bits, and have about 20 layers. On my old machine with a dual 1000 MB/s SSD raid, sometimes can take 5 minutes to save one of those files, on the new machine, takes me about 1 minute.

Another thing is PS and LR are using a lot the GPU right now, like try to use a blur from the blur gallery with and without the GPU and you will see the differece. in one of these files making a field blur with about 50 pins, and blur of about 150 average can take about 20 minutes with the GPU OFF, and just about 20 seconds with the 980, and a minute with the 680 of the old machine.

For 3D rendering I have a BOXX renderfarm with 10 Blades which can cut me a 30 minutes render to about 2 minutes, and the best, I can use it over VPN but never do... did tested it though...

The other software I use a lot, Flame Premiun from Autodesk, with a dual Quadro M6000 does about 80% in GPU, even with the machine having 40 cores and 256 GB of RAM, it merely uses the CPUs and CPU memory... most of the stuff is fitted into the 12 GB of ram of each card and worked in real time, Now even use gaming shaders to texture, 3D render, does crazy stuff and us just starting....

So going back to this new machine, I knew it wont give me much advantage on speed for rendering, but as the files I use are so big, just the saving and loading time gives me an extra hour a day to be with my family.. or working more... ahahaha... probably the later... Those SSD sticks are killer... I wish they come on 4 TB each )))

 

Holy ****, reading all those core figures, i just jizzed my pants. My gf was looking at me weird.

Why do you care about rendering on this mini computer then lol.

Here i am content with my 50 core homemade backburner farm.

But yeah the IO on the new platform is way more superior.

 

Well... sometimes I do some 3D stuff like that 3D neck for the 3D printer, or bring some work home. And I forgot something, I do a lot of 3D tracking, I was a professor at FXPHD for about 8 years teaching 3D tracking, and I still do 3D tracking at home for anyone that can't do it at his studio, usually are just insane things that no one else can deal with, they send it to me. I just had to track a 3000 4K frames anamorphic with distortion of a camera on a dolly on the a field full of waving grass and no tracking marks other than the pebbles on the road. . I did it on the old computer with 32 GB of RAM and I had to reduce it to a proxy size, was impossible, I was short for a lot, but if I had like I have now a 3000 MB/s raid, I could just played it in real time no need to load it in RAM. I finished the job, but took me about 30 hours... And that makes also heavy use of OpenCL, all the tracking is done by GPU, the pixel flowing calculation, the color correction, sharpening, stabilization, And, the 980 is as fast as the Quadro M6000 for most things.

Once I have to do a tracking for a movie from multiple cameras, 6, to replace the legs of an actor for prostetic legs. I did it on the old laptop. That laptop has made me a small fortune during its life... and is still alive. Just being retired to be the machine for my son and shooting tethered on the studio with Capture One.

The Quadro M6000 has a better LUT table engine, but just that.

 

@victorwol, in regards to hex it octo core CPUs, unfortunately, there isn't anything in the Intel pipeline with that until 2017. A search for intel's roadmap should give you an idea.

However, the next thing you should be watchful for in 2016 is 3D Xpoint / Optane based drives.

 

anyone can explain to me pls, i read all and cant understand anything @@

 

What part?

<summary> @victorwol has a P870DM. When he runs some benchmarking applications, CPU goes up to 95+ C., and the CPU then starts to throttle. Discussed in some the other posts are ways of preventing this situation.</summary>

Are you looking at a specific post in particular?

 

About undetvolt and rising the vcore, can i do that that with my core i5 for lower temp :-??

 

I haven't seen too many ppl complain about temps with anything but the i7-6700K. You don't say which i5 you have and if it is a 'K' or non-K CPU.

I'm not much of an overclocking expert, so someone will correct me if I'm wrong, but my guess is on any Clevo, if you have a Prema based BIOS/EC or you have XTU or ThrottleStop, you can play around with under-volting to see if you can come up with a voltage that is stable, but maintains your current clock speed. Again, I haven't run across any posts which find something like the i5-6600K to be overvolted, so YMMV.

If you have the P870DM, you can start here - http://forum.notebookreview.com/threads/clevo-p870dm-n00bies-guide.789463/

If you want a closer look at ThrottleStop start here - http://forum.notebookreview.com/threads/clevo-overclockers-lounge.788975/page-89#post-10226924

 

My 6700K is overheating no doubt, at regular stock settings, it takes about 30 seconds of stress test to start throtling and about 3 minutes to hit 100C for little moments.

 

Yes, temps are too high. Use your warranty if you have one. If you don't have one, try to undervolt to the point that you're stable. The only way to truly test the stability of your undervolt is to use your laptop as you normally would, and if you get a hard and sudden reboot, then your undervoltage was too much and you should reduce it. As soon as your laptop reboots, it will have returned to the stock voltage, so you have to set the undervolt again (but less this time).

Once you finally have it stable, if your undervolt isn't enough to reduce the temps, the third option is to buy another CPU. And if you're going to buy a new CPU, you might as well get a silicon lottery CPU, which are pre-tested "best of the batch" CPUs

 

Have you tried placing it on on a cooler, even without fans on (for better air flow) ?

Or placing it on top of plastic bottle caps so that it has more air underneath?

 

The machine may well throttle under heavy stress but 100C does seem on the hot side.

 

I have tried to lower the CPU voltage, but then the machine when running at full speed wont go over 3,6 Ghz..... am I doing something wrong???

 

Tried the overclocking thing, but the machine wont boot.... :-(

 

What clocks did you try and at what voltage/offset?

 

you need to undervolt. It is throttling due to heat.

If you have an SLI setup, then you also wanna ensure that you are running dual power adapters 330x2

 

the settings that are in here

Can you email me the setting you are using to go at 4.6 GHz???

 

No heat.... looking at the sensors and is not throttling. I'm sure, CPUs are at about 55C ... no fans running.... may be something else need to be done when undervolting??? change something else? not unly undervolt???

 

Sure give me a sec.

 

it's best to ask this question in the
