[CPU + GPU Temperatures + Benchmarks] - XPS 15 [9560] Kaby Lake

62C

 

Have you ever fixed this? Because I have the same problem...

 

Who are you asking?

 

Haha you!

I get tpm throttling too after around 10 minutes of realbench.

 

Hah, I recommend using the reply button so people know who you're talking to, plus it alerts them. I haven't had time to mess with it because of school. @pressing had a good suggestion, that was to use intel XTU to raise the power limits on the CPU to see if that gets rid of the throttling.

 

Ok, I will do.

Already found out how to solve it. It seems that intel dynamic & thermal drivers (in device manager) are causing this throttle. Deleting those drivers results in no more throttling. The underside of the case gets very warm though, so I decided to reinstall the drivers.
Besides, these kind of benchmarks are very unrealistic usage scenario...

 

There's a review of the closely related Precision 5520 with the Xeon E3-1505M v6 at Notebookcheck
https://www.notebookcheck.net/Dell-Precision-5520-E3-1505M-UHD-Workstation-Review.213844.0.html
Throttling issues reported, but no thermal debugging info, so I guess they had a sample in desperate need of a repaste.

 

Hope it's ok to bring this up... I just moded my XPS 15 (7700HQ UHD) today using CLU and some small heatsink and 17w/mk pads nothing drastically different about where to cool. Only major difference was I removed the tapes offered by the heatsink and used the pad as the conductor between MOS and heatsink. Didn't use too much pad to connect the sinks to the bottom panel in order to make sure the bottom panel stay straight/won't wiggle too much...

Generally feeling getting longer full performance period/reduced but acceptable performance period longer than before. But I still get TDP throttling, though quickly gone right after I ctrl+tab out of game (not back to normal though, PL1 can be as low as 7W and only recover to like 13W after I ctl+tab out). I think I didn't do an excellent job repasting and pading maybe but the CPU never exceed 77C and GPU never exceed 79C (overclocked to 1850 MHz/1850 MHz). And none of the temperature under DELL EC exceed 75C.

My condition was fairly demanding though, World of Warcraft basically setting 7 without any AA and low shadow at 4k (windowed). Firestrike 5600+ and wPrime 1024M 208s.

What else can I do? And how did you guys achieve 6000+ Firestrike...

 

Does i5 version cause throttling? @custom90gt

 

I get TDP throttling. I want to raise the power limits on it with XTU, I just haven't had the time/desire to mess with it. Temps are not an issue anymore though.

 

Search my posts for how I set power limits on XTU for the 9550. There are a few tricks and traps.

Also, you should be optimizing thermals with good thermal paste and undervolt before even thinking about raising power limits as that can be risky. Plenty of tips on this thread. . .

 

What would be the best solution to fixing throttling. I've seen mini heatsinks with thermal pads on top of the vrms like this.

Should i do use these mini heat sinks with a repaste and undervolt for the best performance or just stack thermal pads like they do in this guide. http://www.ultrabookreview.com/14875-fix-throttling-xps-15/

thanks so much!

 

Have all of that and still throttles.

 

well uh what would be the best to reducing heat. The mini heatsinks or the stacked thermal pads?

 

The problem is there's no air flow. I do get lower max temp but it throttles still.

 

Did you try redirecting some of the airflow from the fans?

 

No because I don't think there's that much air Gina come...

 

Got my XPS 9560 last week, and been playing with ThrottleStop, but I am slightly concerned that it is not actually undervolting (that or my cpu was volted very high indeed) As currently its prime95 stable @ -.375mv cpu -.245 cache, and -.375igpu?

Current load voltage is at 0.89V.

I have repasted, and padded the VRM (with some old GPU strips), but I do also have a notebook cooler, which is helping keep temps between 65-75c.

 

Are you sure TS is turned on? How are you testing with prime? What's your load voltage without TS turned on?

 

Well I have the button saying turn on and turn off. Pressing it makes no difference to voltage readings. Also HWMonitor shows the same offset settings as TS regardless. I have used it on another laptop, and doing the same procedure, when the voltage got too low it just BSOD. Also I cannot get the cpu cache lower than -.1455 without funny things happening.

Prime 95 is running the blend test on all 8 cores. I test for 1hour at a time, then 12 hours overnight no errors at all.

What does seem odd thought is that my cpu resting state, the multiplier doesn't drop below 12?

edit: Just set cpu core to -.8mv, and nothing changed, so it isn't applying the undervoltage.

 

Pushing the turn on button should make it change to turn off. I can see the VID change if I adjust the voltage in throttle stop.

Also Test with small fft's for stability testing.

 

Yea it seems that Throttlestop won't apply anything lower than -200mv. As it looks like without any volting my cpu is 1-1.1v. I just tried -.8mv with XTU and it crashed (wasn't surprised).

Yea I would normally do small FFT, but as that generates excess heat, and its the heat that causes the stability issues (day to day it is never going to get that hot) i'm not worried.

 

Then why even bother stress testing?

 

Prime 95 Blend is still a stress test, pushing the cpu that will cause it to hit 80c, as part of a mixed load program, using small and large FFT just not continuously.

So the fact it hits 80c, which is between 10-20c higher than in normal circumstances and is still stable for 12 hours suits me, as 10-20c can make a massive difference on the stability of the CPU! Just look at the difference between air and water o/c potential.

If I was being pedantic, I would say that you have to complete 12 hours of Intel Burn Test, as that gets things hotter than prime 95. Also I have done this happily for 5+ years on various computers, have an AMD 1100T which under stress testing I used the fans on max speed, and undervolted by 0.5v, then after finishing stress testing turned the fans onto their lowest setting, and not had a BSOD since.

 

From Kaby Lake Overclocking Guide [With Statistics]

 

Thank you for showing that, very interesting how things have changed!
After having a further play around, realised why the idle voltage wasn't dropping below .55, as that is the lower limit.

Also found out why XTU was crashing, as it applies the same voltage to CPU core and CPU cache. It does something similar with the iGPU too.

 

Why not use ThrottleStop instead? You can put different Cashe voltage vs. Core voltage with TS

 

Temps aren't the biggest factor when it comes to stability when you're undervolting. If you really wanted to heat things up, you'd use ROG realbench because it'll stress the GPU as well. I can run my CPU at a much lower undervolt, but it has random BSODs when going from a very high workload to nothing at all, and by random I mean once every few days. Not worth it to me.

Also you need to set the cpu cache to the same undervolt as the cpu. Your iGPU can be different, I find mine works well at -.1406

 

No need for equal voltage for Core and Cashe with stock or slightly increased clocks. Run lower equal voltage for Cashe and iGPU vs. Core for lower temp.

 

I'm not sure what you mean by run lower equal voltage for cache and iGPU means, but according to Unclewebb:

"I used to believe that these had to be adjusted equally but it looks like the Cache Voltage can be adjusted to the same value or a greater value compared to the CPU Core voltage. If the core is set to -100 mV then the Cache voltage has to be at least -100 mV too but it can be undervolted further to -150 mV or whatever."

So run them equally or you can have it more undervolted. I don't see much benefit from running it at a lower voltage since most of the consumption comes from the CPU.

 

Sorry, I should be more clear. Lower Cashe and iGPU voltage vs. Core voltage is equal higher undervolt for mentioned Cashe/iGPU. It's proven that this will help for lowering max temp. But will decrease bench scores and make instability with higher OC. Was the same for Skylake. Because of this results, Unclewebb stopped up making changes for voltage settings as he first thought for ThrottleStop.

 

Did you try running Unigene Valley? As running the basic benchmark in full screen (admittedly 720p), I had similar results to you with Firestrike, but unigene was +15c.

 

Very interesting!

 

Hey guys did anyone else try @iunlock 's mod?

I'm seriously considering it just because why not, and would love to hear other people's opinion/experience. The one thing kinda worrying me is that the copper sheet is obviously conductive, and having a huge conductive material over a part of the motherboard is a bit scary.

 

I have. jk

You can first go with the heat sinks/spreaders and see how that helps without using the copper sheet. I have two XPS's one with the full mod and one with just the aluminum heat sinks /spreaders.

The mod has to be precise for it to work well. I'd not done properly it'll give diminishing returns.

Try the heat sinks first and see if that helps.

::iunlock::

 

An answer from the modding guru himself !

I'll try with the heatspreaders first like you mentioned ! Do you see an improvement on your XPS with only the heatspreaders?

 

Yup I do. It does help keep things pretty tame.

Advice: If the heat sinks come with adhesive, avoid using those. Instead, remove the adhesive and use a non conductive paste and thermal tape to secure the heat sinks in place.

::iunlock::

 

Got it, the ones I order indeed come with adhesive. While I'm quite used to ordering thermal paste/pads, I've never ordered thermal tape is there anything you'd recommend checking to make sure it's good?

 

I did iunlock's mod a few months ago and I haven't had any issues even taking the laptop to the hospital every day. The heatsinks help isolate the sheet from the board.

 

Well 9560 is holding temps well still! Gaming the CPU/GPU will get upto 75-76C max and prime...well see for yourself.



I changed the power setting to adaptive because I didn't like how on plugged in it would never downclock...something in the high performance power settting doesn't downclock the CPU. Now it does and the CPU max voltage is a little lower with this too! Working great for on battery power too!

 

Hi I am new in this Forum,
I read both this thread and the 9550 temperature observation and really liked what you guys did. Great job !!! I just ordered the 9560 and I will repaste and undervolt it. Thing is I like the idea of the heatspreaders on the FET´s, I would like to order some, can anyone tell me the clearance I have for them? Or which dimensions I should order?
I saw some people using thermal pads on their SSD, does it get hot? Never thought of SSD´s reaching critical temperatures, should I?
And I also have a question for @iunlocker: " Did it help with temperatures, to just remove the copper on the bottom plate? And I did read that you told someone to use thermal paste and thermal tape to stick the heatspreaders to the FET´s. How should it be done? Make cutout in the middle of the tape for some paste or use paste on the contact point of spreader and FET and taping the spreader to the FET, with the tape on the sides? (Didn´t see any tape on the sides of your FET`s). How have you done it?"

PS: I dunno how to send private messages in this Forum, is there a way to ask him directly or did somebody else tried it?

 

@iunlock
Yoo need post minimum 5 posts for using PM

 

Oh, that´s why I couldn´t find it! Thank you!

 

Let me see if I can find which ones I ordered.

*on edit*

well that was easy, here is what I ordered:
http://www.ebay.com/itm/20pcs-Alumi...027375?hash=item339fb8e7af:g:uBsAAOSw34FVD8Jn

6.5x6x3.5mm

 

Thank you very much, now I can order some my self
@custom90gt
How did you connect them to FET´s ? Thermal Tape?
Did you measure how much your temps went down from putting these on?
Does the vram still hit the 90°C mark?
Is there stil throttling?

 

I used double sided thermal tape to connect them. I don't recall exact numbers for how much they went down but my VRM never hits near what it was before. I now get TDP throttling.

 

@custom90gt Thanks you´ve been really helpful !!!
I just stumbled upon page 14, how could I miss this! I read the whole thread and missed a page with some of the most important answers! I´m sorry for asking things that were already mentioned!
Do you know whether everyone has still TDP throttling, or did iunlock get rid of it? (I am not a native speaker and tend to miss some points)

So for now I´ve ordered everything I need! My XPS should arrive tomorrow and I will start with repasting and undervolting, after I benchmarked it in its original state for comparison. (I will use the Kyronaut, since I never used liquid metal and laptops seems to be a bad choice for starters)
Before I can encounter the FET heatproblem, I have to wait. I ordered exactly the same heatsinks as you guys, but I live in Germany so it may need some time to be delivered.

I keep you guys updated when I am done.

Special thanks to @custom90gt , @pressing , @iunlock and @GoNz0 , I read all your comments about the XPS and I am really thankful for the great advice!

 

It is impossible to eliminate a CPU hardware cap as you can always find a way to push it with various benchmarks, the idea is to get it to stay below with whatever application (or game) you are playing and call it a day if you make it
Never use synthetic benchmarks as a basis as they will normally smash into the 45w wall straight away, probably straight to 56 for the short term cap.

 

Oh, I know I just like every thing to be as cool as possible
Thanks, I may just be a bit overzealous, I always try to set every thing up as good as possible.
And I thought, if it´s TDP throttling it must hit 105°C at some point and I would like everything to stay under 80°C. So my assumption was, if it doesn't throttle on a Benchmark, no component of the Laptop will reach critical temperatures under normal conditions. Most powerful application I am gonna run is Catia V5 (CAD-Programm) and maybe some light games like Planescape Torment or Dark Souls 1. I don´t think the Laptop is ever going to have a TDP problem. I also tweaked my old Laptop and it lasted me almost 7 Years, that´s the reason I bought the XPS, I want a good quality chassi with decent power and a long lifespan. And I like my machine to stay quiet with good temperatures. (Also tweaked my car in this regard, it´s not tuned for more power, but for a more reliable engine)

@GoNz0 Is it recommendable to disable Turbo Boost or to limit power consumption to 45w?
A car engine is less efficient, when it runs in its upper RPM range. It puts way more heat out and consumes way more gas for the power output you get extra. Is it the same with the CPU? I ain´t as good informed on CPU´s as I am with cars. Or is this nonsense because only single or dual threaded programs get this CPU to turbo boost, so that this won´t heat it up over 80°C?

 

OEMs can put whatever temp/throttling limits they want with cancer firmware!! Asus f.eks put down to 82/83C for some models.
