Dell 7570 gpu thermal limit

Hi guys,
I have just bought a brand new dell Inspiron 7570 and looking to online reviews i noticed that the worst thing on this machine is the thermal throttling on the gpu (940MX 4Gb DDR5) because it is limited to 70°C (by default the actual gpu limit is above 90s).
I know this is some sort of bios limitations, so... anyone have figured out a solution for this problem ? or maybe Dell released some update ?
Thank you all guys

 

I have the same problems. I don't know what to do. There is no VBIOS available for 9 and 10 series cards.

 

It’s by design.
Some insights into why... How and why Dell cripple the performance

 

you can change thermal compound

 

i have actually changed the thermal compound, but i maybe went wrong because i think i made a mistake removing a pad form the CPU... i have put an Artic Silver pad on top of the little chip right nea the "mainCPU".
any suggestion on what to do on that heatsink ??(images below)

What compound are you using? Looks you put too much compound on it.
70°C was limited by vbios, I did not see any modded vbios for this model.

 

yes you're right they are limited in the vBios so cannot do anything.
I'm using thermal grizzly Kryonaut, i have read that is the best one you can put on laptop(except from liquid metal obviously). I have not reopened it yet, but i'm planning to reapply the thermal paste and maybe put a thinner thermal pad(0.5 mm) or maybe just put a lot of thermal paste so that the chip touches the heatsink.
i have started another thread on this topic if you are interested.

Haven't seen this thread, but I had similar questions to this issue, which I just wrote in another thread. I'll just copy it in here:

(Note, that I haven't got the Inspiron myself, but thought of purchasing it, until I read about this throttling issue)

 

maybe it will help i think it is not a bad idea...
I will try in these days some of the things that people have suggested and let you know how's going on

 

Now I've also digged further through the Dell XPS forums and there are obviously some tricks to get "undervolting" for the GPU done. This is achieved by using MSI Afterburner and change the Clock/Voltage curve. Maybe it works also for the Inspiron?

Damn this is almost science... Ok, what are the options all in all:

- Manually repasting GPU and CPU with better thermal grease (I don't know which is recommended though)
- Undervolt CPU with Intel XTU or Throttlestop (because CPU and GPU are on the same heatpipe, it's good if the CPU is cooler as well)
- Undervolt GPU with MSI Afterburner via the Clock/Voltage curve editor
- Using thermal pads between VRMs and bottom panel to dissipate more heat

(Though, I'm not happy that one must go through such hassles. Also risks the warranty)

 

For what I know:
- the 940MX since it is not a Pascal GPU cannot be undervolted using MSI Afterbuner, so this is an option to eliminate
- undervolting the CPU with XTU or Trottlestop (i have done this) is pretty easy and can lower temps of the CPU expecially under heavy load, and since the GPU and the CPU (as you said) are basically cooled by the same heatpipe, lowering the CPU temps will surely be a good thing even for the GPU.
- Repasting is always a good thing to do, and reading online seems that the best paste is Thermal Grozzly Kryonaut (except for liquid metal), i have actually repasted mine (see this thread for more info http://forum.notebookreview.com/threads/cooling-solution-suggestions.814576/)
- Thermal pads... I need to try them

 

After my old laptop kicked the virtual bucket (for those interested, it was an ASUS K56CB - lasted me 4+ years), I decided to get something better not just in terms of specs but also design.

 

As many of you probably know, there aren't many laptops on the market that can tick 'em all but one of those that can is the Dell XPS 15. This laptop, while great in many ways, has its fair share of issues from dead/blocked pixels, backlight bleed, screen flickering, bad WiFi card, thermal issues and the list goes on. Granted, you'd have to be a pretty unlucky bloke to get a unit with at least a couple of these issues so I decided to try my luck and buy one. First unit had the most horrific coil whine and backlight bleed I have ever heard & seen. I had to return it and get another one. The replacement had dead pixels and pretty bad clouding.

Decided to return it once again just to get a unit (from a different batch) with the same issues. For a laptop with a premium price tag, Dell seems to not really care about quality control. The store that I got the laptop from said they don't want anything to do with me after exchanging 3 laptops so I contemplated getting it off of amazon but living in a country where amazon isn't available meant I had to rely on shipping services to deliver a 2K laptop in perfect condition.

 

I've noticed some Coil Whine in my laptop too, and the Dell support told me that this is a problem on the i7 model of the Inspiron 7570... Can i ask you which model did you have (i5 or i7)?
Then i have even some problem with the audio speakers... they sound very crappy, even playing a youtube video with someone talking they sound very bad when the tone of the voice is slightly higher... Does anyone have same problem ?
