Surface Book 2 throttles excessively, often down to 0.4 GHz

I've recently purchased a 15" Surface Book 2.

When compiling large projects in Visual Studio 2017, I find that the processor often throttles excessively, often down to 0.4 GHz. As a result, compilation takes several times longer than it does on my 5 year old MacBook Pro. 

The Core Temp app shows that the CPU at this point is at 50-55 degrees Celcius or so.

The following question touched upon this problem, but the proposed solution did not work for me:

Any ideas on how to fix this?

Thanks.

    yeah this issue is affecting me as well, latest Windows 10 updates on my SB2 15". Happens when I'm gaming, my frames that usually sit at 60fps, suddenly drop to 30fps until I use ThrottleStop 8.70 to further lower my CPU power draw and then frames go right back up to 60fps.

    For the throttling problem, try using ThrottleStop 8.70 and check the Disable and Lock Turbo Power Limits option in the FIVR window.

    The turbo power limit being accidentally set to 0 and causing throttling is a bug.

    here: https://support.microsoft.com/en-gb/contactus/surface/

    I urge you to contact them, they need to know. I got a new device in the door today, and after spending hours setting everything up and moving all of my files, after a whole day of no issues (it was 26C) in denmark today, I wanted to kick back with an episode of a show I am watching, 15 minutes in, and it started throttling again!

    I just wrote a big writeup on this exact issue myself, but luckily I found this thread, I am seeing the same exact problems, it is happening from even just watching youtube for god's sake. 

    Is there a way to work around this issue? as we all know full well, this device is really very expensive, and I've had mine since april, so a refund is off the table. I was on the tangent that I must have had a badly binned CPU, but seeing as it's happening for a lot of people I now know that can't be the case

    Same issue here.

    Started happening just as the European heat wave hit with high temperatures in the office (~30 degrees celcius).

    After 2-3 hours of work the laptop drops to 0.4 Ghz max.

    Placing an external table fan pointing directly at the laptop to keep it cool "solves" the problem.
