What you are seeing is correct. You need to double the number to get your speed. Your system is using the memory at 1333 settings (if you looked at in your BIOS you would see that as well). You are good to go.

Yeap as said you double the speed shown in CPU-Z to get the equivalent speed. This is because the RAM is DDR (double data rate).

Minimal at best. Not much gained from OCing memory. CPU and GPU OCing is where you see the most impact. If not careful you can make the whole system unstable.
