How to tell if all core (and turbo boost) are working?

How can I tell if the processor is running as it is supposed to be in my 9550 i7?
i.e. all 4 cores and the turbo boost?

HWinfo will show all 4 clockspeeds in real time.....

or just use XTU.... the clockspeed shown there (core frequency) will always show the lowest speed any core is running, i.e. if your running 4ghz on all 4 cores and it starts to throttle on the less efficient ones, the clockspeed shown will reflect that. (pay less attention the the 'Active Core Count'... if it states only 1 core is being used it simply means your running the highest possible clock ratios)

from my experience anyway...lol

 

Just checked in HWinfo and it is only showing two CPU real time speeds. Does the 3rd and 4th core only operate when under load?

 

if you run HWinfo in 'sensors only' ....... you should then see all thread activity...

that window is more like chip specs..
