This could be a stupid idea but how about you change your cooler first before you get to the ram. You are being limited by your cooler.

According to this list ( http://www.noctua.at/main.php?show=compatibility_ram_gen&products_id=34&lng=en ) Gskill z series ram is compatible with the NH-D14. Which Noctua are you using? The next time you ask a question, mention your components so that I dont have to ask a second time what you have.
