[SOLVED] Will different memory speeds but same type and manufacturer be able to be used in a pc ?

My personal example
corsair vengeance 2x4 2400mhz
corsair vengeance 2x4 3000mhz

For me....usually they work together.....and usually they run at the lower speed....or if the MB speed is lower than both....they will run at that.
