    Is core isolation important in W10?


    I have an AM3+ PC with an Asrock 880GMH/U3S3 which gets use mainly on the internet. It has an Athlon II 235e processor. Having other more up to date pc's running Windows 11 with core isolation, I was surprised to find that CI is offered in Windows Security. Unfortunately it will not turn on because of incompatible drivers. The drivers are atikmpag.sys, (twice). I have failed to get the AMD drivers for this pc, and wonder if they are not available due to the age of AM3+. Is it worth pursuing the CI for this pc?

    I now see another thread "enabling memory integrity feature" by win10freak that answers most of the questions. I will not be trying hard to get non existant drivers.
    The only thing I am still not sure of is whether core isolation is running even if the memory integrity is not available.

    Hi.

    Take a look at these resources:

    Turn On or Off Core Isolation Memory Integrity in Windows 10
    How to turn on Memory Integrity and Core Isolation in Windows 10 - Scott Hanselman's Blog

    Maybe this could be of help.
