The new heatsink design looks alot better than the older one and it also weighs alot less. With this new honeycomb design the air is let out which ventilates the ram and lets fresh cool air into give better overclocking performance. On the right picture you see in the middle one of the old heatsinks which were standard on OCZ memory before the new XTC release. Each of the memory sticks has a little sticker that says what type of memory it is you have..
