Surface Book 2 throttles excessively, often down to 0.4 GHz

Your newly exchanged SB2 has again throttling issues? Wow this is really bad news. Did you test other stress tests for confirmation? I am at the end of my wits after having spent two days isolating the issue. Not even a clean reset has helped.

I am thinking on skipping the ultra low power CPU notebooks in my next purchase I think. I am wondering what sales support will be offering me when I decline a refurbished device. As far as I can tell, in Switzerland one can ask for a refund in warranty period if the terms of business is not excluding this option for separate cases. The terms are not reserving them so I should be able to ask for a refund. My patient is really running low with MS and I would rather sue them to obliteration than fiddle with their half-baked trash. I lost so many hours and days, I'd rather spent them doing fun things, but MS is not even wise to the fact that SB2 is a throttling mess.

I have had this problem since the start of summer and temporarily fixed it by putting big fan spinning on the device to keep it cool

I think (and hope) the problem can be fixed by a firmware update because when the clock is locked on 0.4Ghz changing power mode unlock it for few minutes

it does yes, but I am far from the only one. It might have been fixed in a newer batch than what most people have, but the evidence of this is still spotty as it hasn't been observed one more than one confirmed case. I can't replicate the issue at the moment as the ambient room temps are around 20 degrees today. In this case, the surface book 2 performs perfectly, and as intended. the spotlight has also been pointed towards some of the big youtubers out there, to try and get some focus on the issue

I have the same issue and can also confirm that ambient temperature has a big impact on how the SB2 performs.

Below is a graph which shows how the CPU Frequency falls down to 0,4Ghz for a couple of minutes (orange line). You can see that there is not much stress on the cpu and the package temperature is fine. I'm usually using VMWare but the issue also occurs if i'm working in Visual Studio on the host. It happens almost always if using VS and playing video stream.

The machine is not usable for any kind of serious work, unless you are from arctic region..

It is Surface Book 2 15", GTX 1060, 1TB, 16GB, Model 1793, 1813

Lot No.: 1803

bought in EU, german keyboard layout

I've reinstalled windows and drivers numerous times. I've switched to the Preview Ring and then received all sorts of driver and surface firmware updates. Nothing helped, the issue is still present.

Of course I've created support ticket and had MS tech representative logged in and I've demonstrated him the issue. After that they have blatantly ignored all my emails for the past two months!
