Overclocking memory

Will I get a performance boost with overclocking memory DDR 3 up to 2133 mHz. Now the computer should RAM of two different manufacturers (two channel mode). Easy 1333 mHz and the more expensive radiators 1600 mHz. Acceleration more than 1866 mHz is not available (I suspect that the problem is in the cheaper straps). It is possible to replace these straps (1333 mHz) on more expensive(which will probably enable to take the higher frequencies), but does that make sense?
