I'm curious as to why my ram speed is 666mhz when it's supposed to be 1333mhz

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).
