Well you can still get 8GB kits that work with big heatsinks, but as someone else stated above, it would have to be low profile. Now all low profile ram is, the heatsink on the ram is lowered down for clearance respect to people that add big bulky heatsinks and or ram coolers. Now i use Kingston Hyper X 1600 and i have used patriot Ram 1333 before as well as both are good brands. GSkill i recommend as well. ah Corsair is another good one. Just make sure if your going to get a dual fan heatsink or has low clearance for ram. make sure your ram says Low Profile. because if it doesn't there is only a slim chance that itl fit
