How to stop Laptop throttling?

I can't play Overwatch for more than an hour on my XPS 15 9550 without my laptop starting to throttle like crazy. The temps range from 70~90C, with 90C being when my FPS kittens itself and I have to turn off the game. Keep in mind that this is on the lowest settings on the lowest resolution. It's getting annoying.

I have throttlestop on with -125mv on my CPU and -80mv on my GPU. Hell I've even gotten a laptop cooling pad, but neither did much to solve my issue.

Does anyone have any other suggestions to solve this problem?

 

Unfortunately that laptop overheats when its components are pushed. You may have to look into getting a laptop cooling pad or something because all XPS 15 laptops have severe throttling problems.

 

I wouldn't call it a problem, just to be expected. Thermal repaste can help a little.

 

Repaste with Liquid ultra if Throttlestop and undervolt doesn't help.

 

Holy crap you and I have the same issue...

The funny thing is when I monitor my temps I do not approach any thermal limits. In fact my CPU gets so throttled it drops to below 70C while the clock speed below 2GHz to as low as 1.6GHz. According to the in game client GPU temps don't go above 80C or so.



I guess maybe I expected a little too much out of a little laptop. I'll be switching to something else when I can (probably going to hold out for mobile Pascal).

 

I think it's a BIOS bug. It shouldn't happen.

 

I have the latest 1.20 BIOS. I don't recall this happening with my other games (though I am not 100% sure, I will have to go try it out again). What makes Overwatch different is that it is heavily multithreaded (according to them it uses up to 6 cores). Maybe there's an edge case around that?

 

I was able to fix it by switching to high performance and forcing 100 % clocks in ts. I never experienced gpu throttling though

 

Try uninstalling Intel Dynamic Platform and Thermal Framework.
Then, check device manager manager and disable the unknown devices and PCI Data Acquisition and Signal Processing Controller to prevent it from reinstalling upon reboot.

 

Quantumslip,

Running RealBench stress test (15 minutes) this weekend, I noted some odd "Power Limit Throttling" in Intel XTU, which dragged down Package TDP & Core TDP (bringing core frequency towards 1ghz). I looked a bit further in GPU-Z and HWMonitor.

It looks like the "Power Limit Throttling" was triggered by the NVIDIA card hitting 80*C really quickly (as every other temperature sensor was mid-60s, or less).

I don't see why the CPU should take such a throttling to maintain the NVIDIA GPU flat out. Shouldn't the relationship be more dynamic? Is this a BIOS problem?

 

because it is a combined heatsink so it has to account for that one way or the other as the heatsink is rated below the combined maximum of CPU IGP & GPU
Laptops always have a trade off when they are this small.
