I believe this deserves it's own thread. I stumbled upon this while researching something else and thought this may be benefit for others. From what I've gathered Core Parking moves all processing to either a core or cores and putting the other cores to sleep. Here is what I found on the subject: Source It appears that some are complaining about it's use and how they believe it effects performance. There is a way to disable it but I'm not sure if that will disable EIST (for example) if you make the change. Here's the gist of it: source The change does not impact any of the Power Options settings for the CPU. Does anyone else have any additional information about Ideal Core, Core Parking and if it's a benefit to disable it as suggested above for even CPU loads? Is there any performance benefit disabling this? And, with this enabled did it have any adverse effects on benchmarking?
