Surface Pro 3 throttling

I have noticed that once thermal throttling starts my wifi connection becomes degraded. I have noticed this mainly when playing online games. Even through the surface can handle the graphics from the game, as soon as throttling begins the game will lag due to the latency from the wifi. This occurs with or without a fan. Using a fan helps the graphics, however it doesn't appear to reduce the degradation to the wifi connection. I am wondering if others are experiencing similar issues? or whether it is my surface?

The main game I have noticed this with is Marvel heroes 2015.

I have seen conflicting reports on the bios update in the beginning of the year helping some people (personally I saw no difference after applying the update to fix throttling and heating)

hi,

i wantet to say thx for this awesome thread!

Lots of research and tests in here. Great work Justing6.

So, it's a fact that a colder Case/Back will increase the power the CPU can drain.

So there has the be a case temperature sensor anywhere right? Any idea where it could be ?

btw Anyone ever tought about a passive Heatspreader instead of active fan cooling ? ^^

Finally, I believe my incessant testing has royal confused my Surface. It now sees its stock running speed at 2.3GHz instead of 1.7, even showing so in the system panel of the control panel, where it says

i7-4650U CPU @ 1.7GHz    2.3GHz

The first bit is just a string, the number to the right is the processor's reported frequency. I'm doing a factory restore on my surface now, but if anyone else with an i7 surface can confirm that their processor info under control panel->system doesn't look like this it would help my tests.

Edit: The factory restore didn't change anything, so it looks like that was just a big waste of my time. I'm starting to doubt myself, but I still think that processor line in system is not right. If anyone with an i7 surface can confirm one way or another I would appreciate it. All I know is that my processor controlling application started out saying that 1.7GHz was the non-turbo frequency and seemed to be able to control the processor accurately, but now displays 2.3GHz as the stock frequency and generally doesn't work correctly anymore.

I too see this on my i7, but I have also been fiddling with ThrottleStop.

One thing I have also noticed is that even after turning off ThrottleStop, it seems to stick the settings. For instance if I'm running it with the multiplier set at 33T, then turn TS off, the processor continues to perform like it is on. Same thing happens if I lower the multiplier to 15.

Anyone have any ideas?

Processor in mine also shows the 1.7GHz and 2.3GHz note. I haven't tried restoring

I wandered onto this thread because I noted that the network adapter may be throttled at high temperatures too--I noted on Halo 2 Vista in a LAN it lags to the point of being unplayable when the surface is hot, but has no problem when just starting a game and the surface is cool

It would still be great to hear from MS concerning this.  There is definitely room for improvement in this area.
