Guy's, I am in the process of putting together a Sandy Bridge based system around the Asus P8P67 Deluxe Motherboard. For Memory, I was going to get 2 sets of RipjawsX 8GB Kits each having 2 x 4GB Matched Pair for a total of 16GB of RAM. Unfortunately, every dealer out here in my country is out of stock for the 8GB Kits. However the 1 x 4GB Single stick kits are still available. Would it be wise to simply get 4 of these for 16GB RAM? Are there going to be any problems running Dual Channel with these or running at the rated speed of 1600MHz?
