Hello,

My 2 week old surface book 3 ( i7-1065G7) is now throttling at a very low speed of .19GHz.  

I have a standard mouse plugged in, and a Microsoft USB-C Travel hub connected.  To the travel hub, i have a 2nd monitor connected via VGA cable.  This system worked well until i plugged in an Ethernet cable to the hub from my router.

I have unplugged the travel hub, and have restarted the computer 2 times now with no luck.

    Same problem on Book 3 13" / 32 Gb

    I also noticed RAM is never used over 12Go, until RAM is at 12Go everything get fine, after all went wrong (CPU cap to ridiculous frequency, no ability to launch new app) and in process manager the most consumming app is system interruption.

    Same was noticed on screen capture made by different people on this post.

    My previous book 2 13" is much more powerfull ... what a pity

    It's strange your system doesn't go above the 12GB limit... for me, I just need some Adobe applications...

    Since the July update, I've not gotten the CPU throttling. I'm dreading it because I need my PC to work and I can't afford to be 2 weeks using a replacement laptop...

    Where do you find (information about) the July update?

    Is it only for certain versions of Windows?

    I'm running Microsoft Windows 10 Enterprise 10.0.18363.

    This page only shows a May 21st update:

    They probably didn't get to update the release notes ;-)

    Based on my experience after switching from a 13.5" SB2 to 13.5" SB3, the SB3 is significantly faster. Especially in development workloads -> see https://www.hanselman.com/blog/ReviewOfTheSurfaceBook3ForDevelopers.aspx

    I'm currently using 20161 Windows 10, because of WSL2 - I believe that the SB3 runs even faster than on 1909.

    However, if you want to upgrade to 2004 and beyond I have learned that you have to disable Memory integrity in order to allow the Intel graphic drivers to work accordingly. Just use Settings -> Update&Security -> Windows Security -> Device Security -> Core Isolation details -> Memory integrity OFF (until appropriate drivers are available).

    For me the only showstopper was the throttling, which - I still have not seen this since applying the July 3 firmware - leaves the device pretty unusable.

    HTH
