I read about a tweak that slves "Core Parking" issues

[netadict]

The procedure was:
- Go to Regedit
- Select Edit > Find... and find this key: " 0cc5b647-c1df-4637-891a-dec35c318583 " just copy and paste without the quotes in the find box.
- Within this key, there is a value called: " ValueMax " This value represents the % number of cores the system will park
- Change the value of " ValueMax" to 0 so that, it matches " ValueMin "
- You will have to find the key a few times and repeat the process for each time it is found - the number of instances will depend on the number of power profiles in your system. To do this go back up to Edit > Find Next. (I had 3 instances of this key in my registry.)
- Do a full shutdown and power-off and cold-re-start.

Is this safe? Does it really improve performance?

If you are doing it for performance when gaming I would just switch to high performance mode. It is a built in power saving feature applied when using balanced power mode. I would leave it, then when gaming or using whatever program has you looking at this switch to high performance mode.

Bad tweak or not?

You can try disabling core parking in a safe way:

Quote:
"A reader asked whether the “core parking” tweak was a myth. This tweak involves using either a program or editing the registry to prevent Windows from using the power saving options for your CPU. However Windows can do this without 3rd party tweaks and manually editing the registry."

Personally I've disabled core parking on my machine and found that it does make a difference. I tried a few ways to apply the tweak and even used a couple of third party programs that claimed to disable core parking. None of them actually worked!

If you want to apply the tweak for gaming purposes my suggestion is that you'd be better off installing "Process Lasso" - the free version has the ability to disable core parking built in along with a gaming mode and settings to switch between available power profiles. You might like to take it for a test drive. I use this on my machine and can guarantee that it works. The only caveat is that you need to remember to either exclude data intensive stuff from the "active process management" or else shut down Process Lasso when data intensive tasks are running like installing windows updates or defragging.
