hi... i own a set of rams...Corsair Dominator Platinum 16GB (2x 8GB) DDR3 2133MHz Memory CMD16GX3M2A2133C9 which i bought already overclocked by last owner. i want to get another set of the same but im sure it wont be clocked. will that effect the way they work together if one set is over clocked and the other set is not? i can see it will matter considering they will run at diff speed. so that means i will have to over clock the new set? or can the old set be turned back to stock speed?
