Ok I had 2 sticks of 1333 kingston valuram installed on my mobo, today I bought 2 more sticks of 1333 kingston ram and in CPU-Z it says my dram frequency is 666.7MHz and my nb frequency at 1999.9MHz. I'm not sure what the nb frequency is but shouldn't my DRAM frequency be at 1333MHz?

Naa it's okay. DDR stands for Double Data Rate which means RAM memories send 2 ''chunks'' of data per clock cycle. So 666,7x2=1333,4 and the same goes for other DDR memory sticks.
