so I recently heard from corsair when i was sending in my RMA that all dual channel kits are made in a special pairing that would guarantee that the two worked in dual channel very well, so even if they were the same exact model and version and size, they might not work as well as if they were paired by the manufacturer. is this true? I had always thought two sticks of the same size would be able to do dual channel. given that the speeds would run by the slower specs. cuz I am thinking about getting two sticks of ram not in a dual channel kit but are the same ones for my uncle.
