If your mobo/CPU officially supports only 1333MHz DDR3 (most CPU's on market from both Intel and AMD) then that value will be used as default. Better motherboards will try and look for highest supported timing/voltage combination. All in all this means it should boot even on motherboards with only DDR3 1333MHz support.
was talking about the cpu. i know most ram has weird profiles like that
