I7 4790k Underclocking

[WWWMWWMWWWWWWWM]

Hi, my 4790k is underclocking itself i have disabled all power saving options in BIOS and windows this does not help i have tries resting the CMOS and also applying BIOS defualts and nothing changes i have even tried over clocking.

Im running prime95 and aida64 as my stress tests i have tired running GTA V and i have tried cinebench but they all underclock its only when im idle at the desktop my cpu is at the clock its supposed to be i.e. 4.2-4.4ghz stock clock or my own overclock (4.6Ghz)
My temps are fine when doing all of the tests or programs

So here is the problem when i run any program or test say for example i will run aida64 after rebooting windowd it will be at the correct clock and about 5-10 seconds after i start the tert it will underclock to any random clock its different everytime i restart windows (4ghz) (3.4ghz) (3.7ghz) (3.2ghz)

And help will be appreciated!

Unpark your cores by using this handy app...http://www.coderbag.com/programming-c/disable-cpu-core-parking-utility

When your CPU is idle it will underclock and lower voltage to save power. Its normal!!

The CPU underclocks when it's in IDLE, because it's not necesssary to consume power without doing anything.
When you're playing games or use demanding programs, the CPU raises it's speed to stock, then if it's needed enables Turbo Boost.

I dont think you guys understand its underclocking underload and NOT underclocking at idle its the opposite you're thinking it is!!!

go into your bios and make sure all 4 cores are properly active.
It could also be that you put to much thermal paste or not enough and one or more of your cores are over heating.

YES, I understood that (see my original response) - unpark the CPU cores. This app will do it for you by changing registry values. Download it here...http://www.coderbag.com/programming-c/disable-cpu-core-parking-utility

What is your motherboard?
It sounds like there might be a bios update that could be applicable.

Is this a new build?
Or, was the pc working properly and this is a new symptom?
