Disable CPU Core Parking Utility
If you are an owner of a new multicore Intel CPU for example Intel core I7 and Windows 7 or Windows Server 2008 OS, you already might notice that some of the cores in your resource monitor are marked as parked. This is a new feature of windows 7/2008 operating system that is made to balance energy consumption by your CPU. So let’s say if you are performing some tasks that do not consume a lot of CPU power, all the cores that are parked will remain in that state. However, if you are running something that requires a lot of CPU power, all the cores, which were previously parked, will be placed in the active state (unparked) to perform the task. And after it’s done, they will be parked again.
All in all, this is a nice feature to save the energy. But if you decide to keep all of your cores active at all times, there is no way to disable CPU parking from the user interface or by running command prompt.
While searching the internet, I could not find any utility that will allow you to enable and disable the CPU parking without having to go and modify the registry manually. So I decided to write one.
This utility will allow you to easily enable or disable core parking for your CPU. The first thing that you should do is to go to a resource manager to check if you have parked cores. The reason of doing so is that core parking is not enabled for all the multicore CPU’s. For example, if you have Intel Q9550 Quad Core CPU you may not see any parked cores at all.
Once you have started “Manage Parked CPU Utility,” you have to press “Check status button” to allow program to search registry for the keys and values that are responsible for the “core parking”.
After search has finished, you will see N number of rows in the list view control along with the Status that will describe if the value retrieved from the registry indicates that your core is parked. But as I said earlier, core parking is not enabled for all the CPU’ s even though registry value may indicate that cores are parked. From now you can press “Park All” or “Unpark All” buttons to enable or disable parking. Also, you can change a single row.
Note that for the change to take effect you will have to reboot your machine. Also Utility should run with Administrator priveleges in order to be able to access registry. This utility does not require installation.
