How To: Unpark CPU Cores for Better Performance (+FPS Boost)

Core parking allows an operating system to completely shut off a core, so that it no longer performs any function, and draws little to no power. But when the cores are needed, only then the operating system can wake up the core and speed step them to work on the load that’s put onto it.

Unparked!

Parked core(s) = Power saving > Performance

Now, what unparking does, is that it modifies a few power management settings so that the operating system will never park cores. Instead of parking these cores, it will step them up and step them down according to the CPU load, and hence, it tends to result in a net increase in system responsiveness (and might also increase FPS in games) at the expense of power consumption (which you don’t have to care about unless you’re an eco-green-ozone-friendly-recycle-ophile, which you probably aren’t if you’re reading this). And so, this means:

Unparked core(s) = Performance > Power-saving

So, let’s get to how you’re going to unpark your CPU cores in order to achieve this increase in performance, shall we?

Method 1: Using the Windows Registry Editor (REGEDIT) [Manual]

Step 1: Check the parking status of your cores

Download the CPU Unparking Tool (skip the ad to download) and extract it. Then run the file “UnparkCPU.exe” and click on the “Check Status” button. It may take some time (anywhere from 5 seconds to 5 minutes, be patient) and then, it’ll show you the parking status of all your cores, like this:

As you can see, all my cores are showing as “Parked” in the status. For you, it may be just 2, or all 4 like me. So now that we know we do have parked cores, let’s get to unparking them.

Step 2: Run REGEDIT

Press the windows key + R, this should bring up the “Run” box. Here, type in “REGEDIT” (without the quotes) and hit the Enter key. You should now have the Windows Registry Editor in front of you, which looks like this:

Step 3: Navigate to the right path

Click on the “Edit” tab and then click on “Find”. Then copy-paste the following text into the search box “0cc5b647-c1df-4637-891a-dec35c318583” (without the quotes). Be sure to check the “Match whole string only” box, and then click “Find Next”. It should look like this:

Step 4: Make the necessary changes to the registry

Now, after it completes the search, the first thing you’ll see is this page:

Registry.png

Here, you need to make changes in only the values of items ValueMax and ValueMin.

Double-click on ValueMax and you’ll see a box like this:

Change the value in the “Value data” box to “0” (zero), like this:

And then click “OK”.

Now, do the same for the ValueMin value, and make it “0” (zero). You’re all set!

Step 5: Reboot your system

No actual description below this subheading, really, I mean I really hope you don’t need detailed instructions on how to reboot your system…

Step 6: Verify if it worked

Run the CPU Unparking Tool again, and hit the “Check Status” button. It should now show you that your cores are unparked, like this:

Unparked!

You did it! All your cores are now unparked!

Method 2: Using a program that does the registry edit for you, quickly and easily [Automatic]

Step 1: Check the parking status of your cores

Download the CPU Unparking Tool (skip the ad to download) and extract it. Then run the file “UnparkCPU.exe” and click on the “Check Status” button. It may take some time (anywhere from 5 seconds to 5 minutes, be patient) and then, it’ll show you the parking status of all your cores, like this:

Status.png

As you can see, all my cores are showing as “Parked” in the status. For you, it may be just 2, or all 4 like me. So now that we know we do have parked cores, let’s get to unparking them.

Step 2: Unpark

Not much to say here, really, but okay, yeah, just click on the “Unpark All” button, and that should do it… See? Told you, not as much fun.

Step 3: Reboot your system

No actual description below this subheading, really, I mean I really hope you don’t need detailed instructions on how to reboot your system…

Step 4: Verify if it worked

Run the CPU Unparking Tool again, and hit the “Check Status” button. It should now show you that your cores are unparked, like this:

Unparked!

You did it! All your cores are now unparked!
