From what I see so far from the benches, it seems to have more positives by turning it on...

I guess it depends what you use. I personally won't be, just because it seems like it won't really make a difference for what I do. It could be useful if you do use some less well optimized multi-threaded programs, but it looks like if your software properly loads the CPU the difference will be minimal or non-existent.

It would appear that the core parking feature affects programs based on the effectiveness with which they can process multi-threaded tasks. 7zip for example, which can keep all the threads constantly loaded sees little difference, whereas things like WinRAR which keep a less consistent load see more difference. I guess this makes sense, since if WinRAR's load fluctuates then windows would be continuously parking and unparking threads as the load fluctuates which would obviously affect performance.

7 ZIP did not keep all threads constantly loaded at 100%. In fact, if fluctuated from 80% load, to 100% load, down to ~25% load, then back to 80%, then 100%. This was observed when running the default 32MB library. It has also been observed that changing library size makes little difference in CPU utilization, nor in overall effectiveness of changing core parking from 10%, to 100%, in this program.

My Conclusion: Setting the Core Parking setting to 100% didn't negatively impact performance in any of the three programs tested to a degree worth even discussing. It's not a bad idea to turn it on, and you may discover additional performance in other applications.

Dont beat yourself its not that great a thing, i have had mine unparked for last few months now using reg edit, in day to day gaming etc i dont really notice anything.
Obviously there are benefits as shown by benches but ...day to day its nothing big tongue.gif

Glad to see somebody made a thread on this though, theres lots of people that will love this thumb.gif

Some applications don't benefit from turning off core parking. Check out the WinRAR results. Turning it off barely affects performance, and can increase performance such as in WinRAR.

I'd like to add that changing this to 100% did NOT increase my system's power consumption (in sig). I'm still at ~65w idle, yet winrar saw the same jump in performance as already mentioned.
