I have 16gb of crucial ballistix sport 1333 cl9. I am upgrading to a z77 board that supports up to ddr3000 I was looking at some 2400 ripjaws but the board supports ddr1333 this is strictly for gaming and my question is should I use the 1333 or upgrade the ram because its 1333? I am a noob to ram so any help would be greatly appreciated.
