Power Limit throttling

[Dwwop]

Hi guys,

so lately I've been experiencing huge Power limit throttling on my Dell Inspiron 7577. I've tried everything that I could find on the internet, but nothing seems to fix my problem.

It all started while I was gaming. After 15 minutes of gaming, my CPU started PLT. Now the issue is happening even on idle, and I don't have any clue on how to fix it.

 

So far I've: 

undervolted my CPU and GPU

disabled Turbo boost

let my CPU run on only 98% at all times through Advanced battery settings

Deleted every DPTF driver and changed ownership in C:/Windows/system32/driverstore/filerepository of every DPTF and ESIF folder, so Windows can't install anything there

changed settings in Throttlestop - Disable and lock turbo clock limits, unchecked disable turbo, bd prochot and SpeedStep and enabled Speed Shift

Cleaned any dust out of fans.

 

Nothing seems to help me. I would be really thankful if someone has any idea on how to fix these issues, because they I driving me nuts, since I cant even use Microsoft Word without PLT.

 

Thanks for your answers.

Sorry for my english

You could try a thermal paste re-app, though that could be difficult on a laptop. 

Does the PLT actually affect usability/temps?

 

I have the Dell Inspiron 5577 and not noticed any problems with CPU throttling or temps

Regarding temps, not so much, but regardinf usability - I can't play any game without my CPU going down to even 0.8GHz, which makes games run around 2-7fps, which is unplayable.

Try updating/resetting BIOS?

As I mentioned before, you could try new thermal paste; but I would only consider this as a last resort effort (could void warranty, depending on when you got the laptop).

 

You could also try reinstalling Windows, it could be a software bug causing it to think its overheating (which could also be tied to BIOS). 

Otherwise I would assume that the temp sensor died, or something is wrong with the CPU.

sounds like a common issue with this model

 

try clean Windows install (not reset), if it doesn't help then RMA (if still under warranty, otherwise you can do nothing)

What power plan are you using?

Performence

ThrottleStop shows EDP OTHER as the reason for throttling.  This is typically caused by one of the current limits.  In the FIVR window, max out all of the IccMax values and in the TPL window, set the PP0 Current Limit higher.

Do you have any Dell specific software that controls your CPU power settings?  Something like this might have gone bad.  There is no use for most of these programs.  It is also a good idea not to run Intel XTU while testing and trying to fix things with ThrottleStop.

Thanks, I've updated bios and applied these settings and while I do not experience power limit throttling in idle nor under load, I now experience Current limit throttling. Any idea how to stop it?

[unclewebb]

What settings did you apply?  Did you change the PP0 Current Limit in ThrottleStop?  To what value?  Do you still have Intel XTU installed?  If XTU is not solving your problem then delete it.  The bios or some software on your computer is not setting your power limits correctly.  You need to eliminate as many of these variables as possible.
