    Re: Windows 10 KB4100347 update breaks Broadwell-E overclocking

    I am having no problems with overclocking my Broadwell-E i7-6900K on my MSI X99A XPOWER GAMING TITANIUM motherboard.
    I have checked and update KB4100347 is installed.
    I have even tried changing my overclock settings and everything is working fine.
    Not sure if I am lucky or if it doesn't affect MSI motherboards.

    I have the same problem on my MSI X99S SLI Krait Edition and an Intel Core i7 6900K running just 3.7GHz instead of my overclock of 4.2GHz.
    I uninstalled the KB4100347 update and then I downloaded the win update tool here (the prevent-driver update tool doesn't work for it, it has to be this one)-> https://support.microsoft.com/en-us/help/3183922/how-to-temporarily-prevent-a-windows-update-from-reinstalling-in-windo
    It allowed me to find the KB4100347 on the win update list and block it from being downloaded and installed. It works without issues. The update doesn't appear anymore when I run windows update and the pc runs at 4.2GHz again.

    My wifes PC running with MSI X99S Gaming 7 and a Core i7 5960X@4.1GHz isn't affected by this update.

    I also was affected by this bug, Asus Rampage V Edition 10 and 6950X OC to 4.4 Ghz, when update is installed working at 3.5 ghz instead of 4.4 ghz. I unistalled this update and blocked it using https://support.microsoft.com/en-us/...lling-in-windo 2 weeks ago.

    Re: Windows 10 KB4100347 update breaks Broadwell-E overclocking

    A classic example of why auto-installing updates, when MS want to, is a non-starter for me. But at least this one simply hit performance .... sometimes. What's utterly unacceptable is MS deciding I need an update, with the result being something I need, right now, not working until I've spent hours trying to work out how to un-bork my machines .... while, either a deadline looms or an editor/client is screaming at me.

    No thanks, MS. Before I do any updates, I clone the drive(s) and do a dry-run on the copy. Only if everything works fine do I update a live system. And I need to do updates whrn it suits me, in a known quiet time, not when you or your systems decide my PC is "ready".

    Though it's not the only reason, that alone kills W10 for me.
