Hello all I want to unpark my cores for my FX6300 so I can have the full power of it, I watched a YouTube video that told me to go into registry editor and put in a code and find the values and change them. I copied and pasted the code exactly but it didn't work, I tried another video with the same code but it didn't come up with it. Help? And if I do unpark my cores, will I need better cooling? Or is the stock fan alright.

Thanks

Funny how no one is checking the Microsoft website for answers since Windows is the one controlling the cores. Im shocked to see that everyone's answer is to trust some 3rd party app created by a recreational programmer(for all we know) and some weekend programmers copy and paste code that may or may not fix the problem.

Read me:
http://support.microsoft.com/kb/2646060/en-us

Microsoft has stated that Windows 7 and 8 was not built to handle the new 4+ core processors and has issued a hot fix to disable the core parking feature of Windows. People need to spend more time doing their research.

Disabling core parking will not give you "full power". Just make sure your Windows install is up to date and leave it alone. You do want to make sure that the hot fixes mentioned in this article are installed:

http://www.techpowerup.com/158534/new-windows-7-bulldozer-patches-available.html

I personally don't know if you need to download patches manually or if Windows update will take care of it automatically.

Will all updates installed, you're already getting the "full power" as is. Windows parks cores only when there is no load. If there is a CPU load high enough to bog down half of your cores, then Windows will unpark the rest of cores automatically. In fact, under some conditions things can run slower when core parking is disabled. When Windows parks cores, it makes sure it parks only those cores that share execution facilities with another core. For example, if you run a heavy duty dual threaded application or two single threaded applications, then it is better to make sure that things run on cores that don't share execution facilities with each other internally. On Intel CPUs with hyper-threading and on AMD FX CPUs (where cores belonging to the same module still share some things), Windows will park the correct logical cores to make sure you get the most performance. Of course, all cores will be unparked when you need them.

Actually, Microsoft did not state that. They only said that Windows 7 does not optimize for AMD FX and other modules correctly. It had nothing to do with Intel 4+ core CPUs for example. The Microsoft patch does NOT disable core parking. What it does is making sure core parking works right. That is, you want to park only the cores that share facilities with each other. For example, when you run only a dual threaded application, you don't need to have all 8 logical cores running on Core i7 or AMD FX 8350, some can be disabled. However, you want to make sure that the threads do not end up running on two logical cores on the AMD FX chips, or the same two logical cores that effectively share the same physical core on Intel CPU with hyperthreading.

You dont need those apps they just do the same thing you can do. First go to your bios if you can and disable all power saving functions (you may need your mother documentation to figure this out what is what so to speak) then save bios and go back into windows 7 /8.1. Now go to power options in control panel and put to high performance and then go to change plan setting and then change advanced power settings and make sure in processor power management that minimum processor state and maximum power state are both at 100 then go to task manager and resource monitor and no cores will be parked this is the correct way to unpark cores NEVER edit registry for this and you dont need a app. If for some reason you cant disable in bios then just go to windows and do what i said in power options that works too just better to disable it in bios. If all power saving functions are disable in bios window may not have to set processor state to 100 go to power options to check. Cores will be unparked if minimum and maximum is 100. You can also not disable in bios and just set minimum and maximum to 100 that will unpark them. I would disable in bios if you can.

Doing this only in windows power managment does not unpark cores
