Can i have RAMS with different Frequency?

I have 665 MHZ ram DDR3 2x2GB and i want to upgrade with 1333Mhz memory. Will it work? Thanks!

DDR3 (Double Data Rate) 665 MHz = 1330 MHz. The frequency will be the same. It's best to use identical modules, but 1333 MHz modules usually run at the lowest common timings.

So it will it work with 2x2GB 1337Hz modules?
