    FYI: SMT Configuration Error Affecting AMD Ryzen Processors in Windows

    Yes, just managing core affinity per program (making all its threads use a single CCX) should be enough to mitigate this problem in a simple way.

    Have no idea on how this problem relates to core parking. As far as I know, cores are parked if there is not enough workload and keeping everything on fewer cores is more energy efficient. If your question is about parking cores on each CCX, and how that
    could affect scheduling forcing a process/thread to change to another CCX, than I can't answer.

    I don't know for sure how Windows scheduler and core parking algorithm works, but if they fix it for Zen, I expect that they're going to park more and more cores of a CCX until it is parked, then start parking cores from the other CCX. And, as they keep track
    on how much work the cores are doing, I expect them to shift the CCX that is going to get parked from time to time, whenever possible (user AFK, for example), so all the cores are used evenly.

    About slow delivery, I'm on the same boat.

    Windows 10 only use half of max cpu speed

    one thing I found out recently, is that win10 disables software based core parking by default. under windows 7 it was enabled on my laptop. when core parking is enabled, the cpu is able to reach it's max rated turbo boosted speed because the other cores
    are not being used. On my system 1 core gives 2.8ghz max speed, additional active cores give a lower turboboost ratio. I suspect this isn't an issue for those with the latest and greatest CPU's as the intel specification now calls for hardware based core parking.
    I managed to re-enable core parking using bitsums' park control software. the park control software is also built into bitsum's process lasso software.

    Have you tried this regedit?

    http://forum.cakewalk.com/Windows-7-...-m1861804.aspx
    Just make sure you continue the search in regedit for the key of every instance of the key above.

    Do the cores show as 'parked' in Resource Monitor?

    thanks so much for the .reg <3

    oddest thing, wheni entered them manually prior to my last format they worked fine. This time, manually or via your file.. the entries for
    core parking increase and decrease threshold aren't showing up at all. Sigh. Always something *Sad
