Turbo Boost is going crazy.

post #1 of 5
Thread Starter 
I have my overclock setup using turbo boost at 4.5ghz it usually runs at 1,6ghz unless I run something that needs more, This has been stable like this for 2yrs. Saturday night my PC ran the windows experience assessment by itself and now my turbo boost is going crazy dropping from 4.5 to 1.6ghz and up and down voltages everywhere I dont know whats going wrong and whether it will break somthing. I have reset all settings in bios to stock and the problem is still there its just goes from 1.6 to 3.9 ghz now. Please help.

That's normal. That's the point of Turbo Boost. To allow lower voltages and clocks at idle to conserve power. Then when the CPU is under load, it Turbo's to its overclock speed or whatever the max frequency is set; followed by the additional voltage to allow for the Turbo frequency to be stable.

I know how the turbo boost works but it used to be stable staying at 1.6ghz unless I opened a demanding program but now its up and down every second or more and even when its idle.
I have looked for processes stressing the CPU but have found none.

I'm not sure how power-saving works with SB, but with my 4670k, I like disabling speedstep entirely, locking the cores at 4.4ghz, and enabling the C7s state. The cores still undervolt themselves all the way to 0.0V when they aren't processing anything, but they stay ready for any kind of load, all the time.

That is nothing to worry about. My 3770k turbos just by moving the mouse fast enough.
