FX-8350 running at 1396 MHz?

Hello all,
In the process of thinking about OCing my CPU, I installed CPU-Z, and much to my surprise, it reports the multiplier at x7.0 and the bus speed at ~200 MHz, giving me a core speed of ~1400, which is about 2600 lower than I expected. :p 

Is this normal? Should I bump up the multiplier to x20 (What I think it should be) to get 4000Mhz? Am I just missing something? Thanks!

Edit:
Here's a screenshot of my CPU - Z.

That's because AMD "Cool n Quite" is enabled, it reduces core clock and voltage when the system is IDLE.

Try running any CPU intensive application, or just a game and you'll see the 4.0 GHz up.

it's a power save mode for the cpu if it not being used it will drop the multiplier to save power

Yeah it's working as intended. What you're missing is the power saving features ;)  To test your overclock run Prime95 or similar.

Thank you very much to all!
It appears that you were right, it was "Cool n' Quiet" taking effect.
2nd Question: Before OCing, I ran Prime95, and within 30 seconds I have a Rounding error. OCCT gives me an error within the same time frame. There is no overclock, just stock speeds at 4000MHz. Help? Did I mess something up? :o 

Better Idea : Because this is unrelated, I'll start a new thread for it and try to close this one.

Thanks!
