Dell XPS 9570 8750h Power Limit throttling Extremely bad

[toastdude123]

I have owned my dell xps 9570 i7 8750h since August. I have been having issues every now and then randomly. When I put a stress on the cpu it down clocks to an unnecessary amount. The temps are fine when it down clocks. I cant even render a video without it dropping the clock down. But when it doesn't down clock (below the base) I can easily render a video at 3.5Ghz Any ideas?

increase the power limit through XTU then? Do note that it could get hotter than that in real world usage, XTU stress test isnt the best when it comes to pushing thermal output.

How would I go about that?

the 'core' section in XTU

I'm in there, which one do I change? (Still a noob with XTU)

Turbo Boost Power Max, and turbo boost time/duration. You can try 60 seconds and 30w from the start.

Its not working, no change to the system

Did you reboot the laptop after installing XTU?

Yes, XTU has been on the computer for two months (its fully updated)

You can try use Throttlestop instead

How do I go about doing the same settings in throttlestop? I am also closing XTU to not have any conflicts with Throttlestop.

Dude laptops usually wont turboclock to highest(in your case it is 3.5?) for very long because of two factors.A)Thermal limit(most likely in your case coz your laptop is slim and might not have adequate cooling) B)Power limit.Solution for A)Reapplying thermal paste with a new and better one(kryonaut is a good one).If you dont know how,take it to a laptop service station and let the service engineer do it. B)solution for power limit is not very easy,you could adjust power limit to a point using XTU/similar programs,but dell will have locked the power to a specific range say 30-40W.you cant change that unless you have modded bios(which isnt safe and it is hard to do or find).I suggest you reapply thermal paste,clean if there is any dust built up and try fiddling with the controls on XTU.Thats it.

Dude, I know that laptop don't turbo to the highest, 3.5 was what I was getting, now 0.8-1.7 is not normal! Temps are great, even better since I did a repaste. Zero dust in the system. I dont even get to 30w of power on the CPU, watch the video link and you will see the issue. Cinebench R15 scores are SUPER BAD. I was getting 1210-1228.... Now I am getting less than 600... There is a problem.

Do you Have any more ideas? That didn't work for me

 

When ever I talk to dell I get the generic response "The system is performing as expected"

I saw the video and you are pefinetly power limited/throtteling.Is your laptop on high peromance mode or powersaving?.I checked out a dell forum which addresses the same problem.check it out-https://www.dell.com/community/Inspiron/Power-limit-throttling-no-thermal-throttling-on-7567/td-p/6061898

Few solutions in the forum that caught my eye was

"I've repasting the device then I've found out that the problems is the overheating in the VRMs and MOSFET, i used some thermal pad and it works perfectly now!!"

" What did work for me was:- Restart the notebook, enter the Bios (press F10 or F12), go to the Bios Configuration -> Performance, and disable the Intel SpeedStep option."

and

" After turning on the laptop go in device Manager and uninstall Intel(R) Dynamic Platform and Thermal Framework Processor Participant  and select to delete the driver software for this device.You have to do it every time you restart the laptop"

tbh I don't expect something like the XPS 9570 to do better than that either. My thick laptop (before repaste though) only does 1110cb in R15 while holding 85C with 45w power limit, and it's not like the XPS has special designs like the Asus Zephyrus has to keep decent cooling while staying thin.

maybe the mosfets in the VRM are overheating and throttling? Thermal pads got loose and went somewhere but where it should be, for example

[MohnishDoultani]

So, go to Dell Power Management app and change from "Cool" to "Ultimate Performance" or "Optimal Performance". This won't do Power limit throttling but it might lead to thermal throttling depending on your system (mine is not repasted so thermal throttles on those settings so I keep it on cool and undervolt to -0.100). If I keep it on the Optimal performance I get 3.6 - 3.8 ghz
