CPU running at proper speed?

I have a phenom x2 555 3.2 ghz, but when I run CPU-z it has this display



It says 803.6 mhz with a multiplier of x4. I realize that if I multiply 800 by 4 I get 3200, but whenever I see images online of the same cpu, it says something like 3200 x16. Am I reading this wrong or is there something wrong with my processor? I've been using an old computer for a long time, so it seems plenty fast to me.

I am able to run starcraft 2 with low settings fairly smoothly, so I doubt it's moving at 800mhz.

I've not done any overclocking or changing of the BIOS.
