^title. It didn't used to do this. It's a laptop GPU. CPU+GPU temps are below 70C when gaming. I've attached screenshots of my throttlestop and HWMonitor. On GR driver version 546. I get EDP other and PL2 as the throttle reasons in TS for the ring, GPU, and CPU. Laptop is plugged in with proprietary power cord and windows is set to high performance. Let me know if there's any other info you want.

22watts is very low for that chip from what i can tell from online reading

the power supply issue might be a possibility, but wouldn't that always be low wattage if that were the case?

wind burrow
#

According to this, your power supply is v. low

humble talon
#

yeah it says 22.24w for the power supply under the GPU section

wind burrow
#

the gpu is 39.17w

humble talon
#

oh, they put CPU stuff underneath the GPU section? weird

wind burrow
#

Oh wait, no, i'm wrong

#

10w cpu power draw is probably your problem

humble talon
#

yeah we already know it's power throttling, it's just figuring out why though. did you get a chance to open up those throttlestop images in a new tab?

wind burrow
#

Honestly, i've never heard of throttlestop before, and i wouldn't be able to help

humble talon
#

ah np then. yeah its basically to stop laptops and such from thermal throttling by doing minor undervolts on stuff, and to also bypass all the other little annoying things laptop makers due to underpower their laptops

#

my laptop was fine for years with this program installed. now it power throttles regardless of whether this program is enabled or disabled, so idk

Laptops are too hard to troubleshoot for me...

humble talon
#

gotcha. well i appreciate the help! hopefully someone familiar with this can drop by

@normal sentinel might help

Have you checked the laptop maker's utilities to see if you may have accidentally set a profile that intentionally limits speeds

i also changed the pl1 and pl2 levels in throttlestop to be 70 watts and 65 watts respectively (they were only 30 watts before, but it didn't make a change either way)

This may sound counterintuitive but try setting both of them to Balanced

You should also check the power slider right on the battery icon too and set it to Better performance

And reset the power plan to its defaults too (to be safe, do it for every one that you can. You can do it from the power options in Control Panel. Click a plan's details.)

thanks, just tried all that to no avail. i did discover something though: if i reinstall my nvidia drivers with the clean install option ticked, it gets rid of the GPU power limit flag that you saw inside of HWMonitor, and i get my normal FPS with no throttling!!!

...that is until i restart. then it starts power throttling all over again until i do another nvidia driver install with clean install checked

Hmm. Consider if you have the time to clean install Windows to rule out all software

humble talon
#

i'm absolutely stumped at this point. this is a mega bummer because i won't be able to afford a new PC for a year or more, and having to spend 5+ minutes to reinstall the GPU driver every time i do a restart is... yeah

humble talon
#

so the disk was reformated when i did this

Is the power supply (ac adapter) the original one with your laptop

humble talon

yep, it's the original AC adapter. i also have a new off brand adapter that i tried which made 0 difference
