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.

    Hi T,

    Newer devices have an adjustable power mode to allow you to balance your preference between best battery life and best performance. To view this setting, select the battery icon on the task bar. If your device supports it, move the Power Mode slider to either the Better performance or Best performance setting.

    You may check the this article for tips on how to improve your device performance in Windows 10.

    Here are few things that you can also try:

    Run the Surface Diagnostic Toolkit. The toolkit runs through a series of tests to diagnose your Surface device. The diagnosis and repair time averages 15 minutes or less, but can take an hour or longer. This will also download the latest updates for your device. Please click here for more information about the toolkit.

    Run the Windows Memory Diagnostic tool to determine whether your Surface memory is working properly.

    1. Select the search box in the taskbar, enter memory, and from the search results, select Windows Memory Diagnostic.
    2. Select Restart now and check for problems (recommended).

    When your Surface restarts, the diagnostic tool will run and display the test status on the screen. Although the test may appear inactive, it’s still running. Windows will restart automatically after the test is complete.

    Run the Error Checking tool to scan for errors on your hard drive.

    1. Open File Explorer in the taskbar and select This PC.
    2. Press and hold (or right-click) Windows (C:) and select Properties.
    3. Select the Tools tab, and under Error checking, select Check.
