OCed it to 333 mhz fsb x9 = 3ghz and every other program reports it at 3ghz, it's benchmarking at 3ghz, but cpu-z says it's running at 333x6=2ghz. Something to be concerned about or just forget about it?
Intel's "Speedstep" drops the multiplier and voltage of the processors when they're not under load, thus saving energy and lowering power consumption. When you run something that is processor-intensive, it'll bump the multiplier right back up to where it needs to be, when you're idling it'll drop the multiplier to the lowest option ( six ).
That's normal. It is a feature called speedstep or something. When you are not loading your cpu, it will run at a lower multiplier. load ur cpu & u will see the real speed in cpu-z
