I installed Easy tune 6 software (Overclocking software) but I didn't make any changes in clock speed, I just observed the software. I didn't save anything.
Seems like it's controlling my CPU frequency by it's own without human involvement.
In the "Tuner" tab, under it there is Power On and Target. Actually what's the meaning of these two?
Anyway It displayed,
Power On: 3200 Ghz
Target: 3600 Ghz

After sometime I opened Easy tune 6 again, then I noticed Target is 1600 Ghz.
I checked CPUZ, Core temps, Open hardware monitors and all other softwares I have, every soft displayed 1.6 Ghz.
I immediately uninstalled Easy tune 6 and rebooted but still it was 1.6Ghz. I even reset default Bios setting and cleared the registries of Easy tune from regedit but no change still it's 1,6 ghz.
what makes me confused is in bios it shows 3.6 ghz (with turbo boost) but in the Operating system, the softwares I use shows 1.6ghz.

Here, some images of Easy tune 6,

That's completely normal, it happens due to CPU power saving features. When cpus aren't experiencing much load they will tend to decrease the clock speed to keep things cool and quiet, as well as attempting to save power. If you really wanted to prevent this from happening (isn't a big deal, even for gamers, it'll ramp up when needed), there should be an option in the bios called "energy saving", "cool and quiet", or something similar you can disable. All depends on your preference. As for the difference in start up clock and target clock, it is also completely normal as well, when your system goes under load and there is no thermal barrier, ie too much heat, and it needs to push some more performance to keep the pc from locking up it...

That feature is called Turbo.

Yep I'm sure, I used to have that exact cpu myself, it's a pretty decent chip. Anyway, every cpu I've come across, new or old, in the past 7-ish years have had that feature. Your hardware is fine, and barring any other unforeseen problems, is running exactly as it should.

The clock speed will only fall to 1600mhz when there is no load on the cpu, or while it is idling. While you're gaming, or performing any other cpu intensive task the cpu will go back to it's normal speed, or even higher. You are correct, unless that system of turbo-ing and underclocking somehow gets out of wack (never heard of it), it will never affect performance.
