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.

    I confirm, I've tested all I found on the forums, my SB2-15 is still throttling back to 0.4 GHz. I just Don't know what to do, very disapointed ! Any solutions ? Going to HP or DELL ? What about the 3K bucks ? I was using it for 1 year as Music and Video station successfully and  since one month … boom :-( **** updates.

    我确认，我已经测试了我在论坛上找到的所有内容，我的SB2-15仍然会限制回到0.4 GHz。我只是不知道该怎么办，非常沮丧！有解决方案吗 去惠普还是戴尔？3K钱怎么样？我成功地使用它作为音乐和视频站已经1年了一个月......繁荣:-( ****更新。

    I have solved the problem，update your nvidia drive...on nvidia.com...简单来说就是在官网上下载最新的英伟达驱动。

    which driver #?

    i have tried several from nvidia directly. they mostly caused freezing, BSODs, and failure for the computer to start....

    I'm on my 4/5th Surface Book 2. Overactive throttling is on all of them. Behaviorally I've learned that you can change the power profile for temporary relief. Keep the battery icon in your tray, click and switch the power mode from recommended to better performance then back. This will "trick" the device from under-throttling on ambient temperature.

    I have solved the 0.4ghz problem. Is an OverHeat Protection..

    Follow those step then you can fix it:

    First rename file "C:\WINDOWS\System32\drivers\dptf_cpu.sys" to disable "Intel(R) Dynamic Platform and Thermal Framework Processor Participant".

    Then reboot Download ThrottleStop and uncheck "BD PROCHOT".

    The Final, Limit "Turbo Boost Long Power Max" in ThrottleStop TPL Setting to 14w to prevent from OverHeat Poweroff!!!( 14w is fine on my surface book 2 15', you need try your self for best value) 

    A Tip ThrottleStop Often crashing, you need to keep it running. e.g: some watchdog program.. 

    我解决了这个0.4Ghz的问题，这个问题是由于过激的过热保护机制造成的....

    你可以尝试根据以下步骤修复这个问题.

    首先重命名 "C:\WINDOWS\System32\drivers\dptf_cpu.sys" 文件 来禁用掉 "Intel(R) Dynamic Platform and Thermal Framework Processor Participant".

    然后重启 下载 ThrottleStop 打开并去掉 "BD PROCHOT" 的复选框.

    最后 为防止过热关机, 你需要在 ThrottleStop 的 TPL 设定里设置 Turbo Boost Long Power Max 为14w. (14w 是基于我的 surface book2 15', 你需要自己摸索最佳值...)

    顺便 ThrottleStop 会经常自己崩溃 你需要为他启用一个守护进程 保证它一直在运行.....
