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.

    For me this is solved in a straight forward way. 242 people here have the same issue. Let's add 100 from reddit. That's almost 350 people. I say we collectively sue Microsoft for failing to deliver a working product, misadvertisement of it's capabilities and loss of productivity. Loss of productivity depends from person to person, or company to company. We have been waiting to solve this peacefully and gave them more than enough time. They REFUSE to solve this issue because it would hurt their bottom line.

    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....

    After struggling with the same problem for over a year, I think I finally find the crux: BD BROCHOT. (Correct me if I'm wrong) This feature allows the system to do TDP throttling not only when the CPU is overheated, but other components of the laptop. In the case of surface, I think this "other part" is the general main body temperature of the laptop, not the dedicated GPU or the built-in GPU. That might be why the problem always comes when the context temperature is over 30 or even merely over 25 degree celsius. 

    No here is my setting (under TS 8.7, with CPU undervoltaged by ~100mv, GPU by ~80mv), and the problem seems totally gone. If not, there is another way in the next posting.

    Hi William,

    Throttling issues can be caused by several factors. Have you done any troubleshooting steps? You might want to boot the Surface in safe mode with networking, check if the issue persists. Click this link for steps on how to start your Surface in safe mode.

    Let us know how it goes.

    Regards.
