How to explain Thermal Throttling to senior representatives of Dell(India)?

If your fully locked down BGA can run fully load with Intel's spec (45w TDP), everything works as intended. It seems so. Undervoltage can probably make your chips running higher clocks due lower power usage(within Intel's allowed 45w). Intel haven't guaranteed you fully Turbo boost!!

 

Thanks for the reply. I have also tried undervolting and my max sucks and can only do -20mv as when I tried -25mv and running OCCT for 30 minutes my desktop icons got rearranged and my undervolt settings went back to default. T_T. Guess my only option will be liquid metal right?

 

Yeah, Liquid metal will lower the max temp, but not guaranteed you higher clocks or you can increasing your undervolt. Your processor running already under thermal throttling threshold in Aida64. But you have a small possibility for increased undervolt with very low processor temp.

 

ahh ok.. thanks.. seems this is one of the reason why the 6700hq is one of the worst or the worst bga processors.. anyways I learned alot from the helpful community and your one of them Papu.. This is the result of having your first gaming laptop and lack of knowledge.. Anyways thanks again..

 

Thanks One of the reason I push out correct and proper info in threads like BGA VENTING thread. + other threads as well. Info out to the people!!

 

If your temps are below 90C, consider yourself lucky. 90C should be the max your processor reaches. You can't do anything about the processor. "Silicon lottery" as people call it, because each individual chip of same processor family might vary.

Also Aida's FPU+GPU is a synthetic test, you will never use 100% CPU + GPU. I at least can't think of any scenario other than training neural networks. So, if your temp doesn't cross 80 when playing Witcher 3, fantastic!

Also, 6700HQ can be undervolted upto -150mV(I've tested this on two laptops). But, I've heard that this varies per chip, so you should figure it out

 

i had two different motherboard of 6700HQ with one reaching -190MV on core and cache, another one with -175mv on core and cache, i just bought a aluminium plate to place on top of PCH.. max temp 77C.. most part stayed below 74C, thats almost 4-5C difference.. but to be honest, when there is lots of load on Bus Lanes, somehow i keep getting minor Spike on Temp, example saving shadowplay videos, you will see sudden spikes, due to load on HDD, and other components..

 

Yeah the nvme drives stress the pch indeed the most. Transfering files heats up the pch more than actual gaming in my case.

 

Are there any forum posts on people reporting throttling to 800MHz on 15R2 or 17R3 with 6700HQ? Want to send it to Dell

 

As far as I know only with the 4710HQ & 4720HQ. BUt yeah like I said, you are operating near and or out of spec. High humidity/high temperature. YOu really have to optimize your cooling as much as possible. Use liquid metal paste and fujipoly thermal pads. The heat has to get out of your system as fast as possible for it to work.

 

thermal pad is not really necessary unless you're doing some major overvolting on the machines

the motherboard capable on the 17 and 15 maxwell models, and can take up to 1.2v overvolt *if* the VRMs are cooled enough

 

Thats true, but his ambient temps are tough on any laptop though,

 

Oh right, India.

Maybe want to invest in 6w/mk, good enough if not overvolting but need to compensate higher ambients.

 

@Mobius 1: Do Team LHz test their PC under standard room temps of 25C or above. I don't how Mr. Phoenix's PC temps are less 70C when its clocked to 4GHz, considering Dubai has high temps.?

 

controlled room 24-25c (measured with thermistor kit from asus motherboard x99)

 

Finally, Dell has replaced the motherboard and also said they had used "special" thermal paste given by R&D team. Whatever, temps are staying below 85C at any amount of stress(CPU+GPU), no thermal throttling and no 798MHz drop. Surprisingly, no surface heating too! Brilliant

Thanks everyone for pitching in. I guess a huge headache is now over

 

Ask Dell support what brand the "special" thermal paste they was given by R&D team

 

Is that temps on AIDA64 Stress test with CPU, GPU turned ON? If so, its great. Another point is that, its rainy season so you will see drop in temps. Just post a screenshot, if you don't mind.

 

No. It's my own program(Floating point Matrix multiplication, 8 threaded, using AVX2 instructions : which used to drive my older motherboard to 100C easily). Dell strongly opposed using Aida64 saying it would have "deteriorated" the processor and hence I was getting 798MHz drop(Funny, I know). So, I had to write my own C++ code to demonstrate that "third party Aida64" are also programmed similarly. Since they couldn't tell me not to write programs on my laptop(sole reason why I bought it in the first place ), they had to agree that motherboard was faulty!

And for GPU, I ran Metro Last light Redux with Ultra high settings and Heaven for some time. Metro has much higher power draw(81W) compared to Aida64 and Heaven(About 67W). Ran both my program and Metro simultaneously. Package temps in Intel XTU never crossed 81C and HwINFO said 86C on Core1 as max, others were around 80-82. Surprisingly, core temps are also almost even with a difference of about 5-6C.

And yes, rainy season I know. But still, current temp is 26C with a higher humidity than a month ago. And one more thing, I've undervolted by -160mV(This motherboard's CPU could be pushed till there compared to -150mV of older one. Yet to see if it can take further undervolting which would be awesome). So, even that's helping

Also, max PCH temps was 60C! I've seen it go to 87C in my prev motherboard. Sorry, no pic since I restarted the PC. If I run any tests again, I will post the pics. I'm remembering all these values since I'm surprised myself that it has been fixed atlast

Nevertheless, if undervolting helps, if the new motherboard(and "special" TP, brand name of which I will inquire about shortly for @Papusan ) helps, great. I won't have the headaches I have had for more than two months

 

Its good that you can write such app to test it. Did you use Single precision or double precision to test it, maybe I will try some. What was the size of the dataset?

 

horse ejaculate fluids

 

Maybe thermal paste application method has changed from stamp pad to normal manual thermal pasting??

 

@Mobius 1 meant the <new> thermal paste

 

The difference is huge, on winter i had 0 throttling on my R2, the same if i run on march - july.. its opposite.. are u sure ur PCH max temp was 60 when running extreme test on both gpu and cpu.. and im wondering what kinda speciaaaall paste they used.. RND team head is using GC extreme that i know well, i suggested him that.. before that he was using ARTIC MX4.. but glad to hear your problem is solved.. have fun

 

Double precision. Try Eigen Matrix multiplication library. Will help you not dive into AVX2 instructions yourself. You can simply enable AVX2 in VS. And dataset size is 8192 matrix, 8 of them, running in parallel in an infinite loop. More or less the kind of work I do

I'll ask them what paste they are using.
Also, I had my PC running for more than 5 hours now and then ran some tests for @Vasudev . PCH went to 70C then started coming down. Some pics I've posted

At any rate, these results are WAY better than before, though they may not necessarily be the best. I'm fine with it. 0 throttling in most demanding games, applications and my programs. All I asked for

 

Nice temps @sagarbhathwar

 

@Mobius 1 @Papusan @Vasudev @VICKYGAMEBOY The thermal paste is Arctic Silver Ceramique 2 Trilinear! - http://www.amazon.in/Arctic-Silver-Ceramique-Compound-CMQ2-2-7G/dp/B0087X73AM I'm guessing probably

 

Arctic silver Ceramique 2 will have good temps for a week or two, then the same story: sudden temp spikes. I resorted to repasting every week, then bought CM Maker gel Nano so far the temps consistent for a month and still going strong w/o new thermal pads.
@judal57 was suggesting me to buy either ICD 7, TG-K, CM MG Nano and TG-C. Finally chose CM MG Nano. Its little thick and viscous than Kryonaut. Even @iunlock and @Mobius 1 can vouch that TG K is smooth and more viscous.

 

I never tried it, @bloodhawk did.

 

Sorry @Mobius 1, I ate some words whilst typing. My actual sentence was: TG K is smooth and more viscous which means it spreads very easily.

 

My Master Gel Nano was much thinner than my Kryonaut.
But then again these guys are always changing something or the other. Or just could be the batch.

 

I tried that CM nano on my R1 a year back, before I was about to inform others i just wanted to test the performance on my own, with multiple applications on different laptops and desktops, its simply one of the best you can get, atleast in india without paying duties for importing, and let me tell you straight, its pretty good for its price comparing ICD7 or kryonaut.. not top notch.. but worth it.. don't waste money on AS5 or any other low end ones.. I just imported Kryonaut and GC extreme from UK.. once I get my new motherboard, ill test those 2 as well.. and I got 28x28x3mm ultra thin heatsink for PCH from China.. I had to buy in lots.. each lot will have 20 pieces.. so anyone from india needs that.. let me know.. I can pass it for free.. but remember to use 33+ tape around pch die..

 

CM nano is the best for its price, i'll post OCCT screenshot later. Also, I used @judal57's fan profiles and the paste is very good. <70C on CPU and <75C on GPU on High settings on Witcher 3 for 4 hrs straight.
What happened to your motherboard?

 

Maybe the high ambient temps in my area is the cause. During repaste my room temp was above 35C, that might have changed its specific gravity from 2.6 to 3. xx.

 

Well, ambient temp was 25-35C. @Mobius 1 @VICKYGAMEBOY. I used CM Maker Gel Nano.

 

Even in test bench can't this paste make good numbers

 

@Papusan : The paste performs as advertised. They said the delta temps would be 10C, so it as advertised.

 

On a test bench... Oh'yes. But will this paste have 3.6C delta temp vs. Liquid metal on a lot worse cooling in a notebook? Same as saying you will gain maximum 1.3C lower temp with Liquid metal vs. the best conventional thermal paste used on mobile i7.

 

great.. Yeah ambients are pretty bad here.. 3rd R2 motherboard in 6 months, both of them got short circuited.. its my mistake, remember the thermal pads method me an judal posted long back, that works fine, unless if u press too hard on keyboard side, the metal pins on board touched keyboard tray bracket.. so if you are using thermal pads of 2mm under the keyboard tray.. make sure you have 8 pieces of thermal pads, 4 on each corner.. and 4 on center..

 

@Mobius 1 @iunlock @judal57 told me to use thermal pads of 0.5mm underneath the keyboard. What caused the keyboard metal bracket to touch the board? Did anyone sit on it accidentally?

 

0.5mm too thin.. if u press hard on keyboard.. it will end up touching.. lol.. no one sat on my keyboard.. btw how is ur PCH temps..

 

Here

 

So the better option is not to put thermal pads on GPU memory chips right?

 

@VICKYGAMEBOY: My PCH temps are 80C on stock fan. 60-70C on HWinfo fan profiles.

 

You can use use thermal pads on Backside GPU vram, but I suggest not to remove the transparent sheet which is stuck on keyboard bracket tray.. I actually removed it first, it helped reduce heat, but I found its little on the risky side.. just keep it.. and add 0.5 or 1mm thermal pads.. that should do the job.. and for PCH do you want ultra thin heatsink ??

 

did you peel off the protective plastic cover on the back of keyboard? or was it not there in the first place?

 

that's good, I wouldn't worry about it

 

At the moment, No because I'm asking Dell to replace the battery due to overheat on battery mode for launching and running MS word etc. Battery feels so hot, i mean even the palm rest is too hot to touch.

 

Just FYI

TJunction is 99c. Anything over 99c will in fact damage the CPU. This is a fact, Dell saying 100c is OK is flat out wrong. Your CPU drops clocks until it gets below 99c or it shuts off. Simple as that.

 

alienware 1note7?

actually the tjmax for alienware is set at 97c from what throttlestop says, not sure if this is accurate or not

adjustable per bios settings if you want it to shut down at a lower temp
