I bought one dimm of ddr3 critical ballistix sport 8gb 1600. I know that normally you buy in sets but in my case i could only afford the one at the time. So now i want to upgrade and was wondering if i buy from the same seller same 8gb crucial ballistix sport 1600. Can i put the two together as a 16gb without problems. Also my motherbord only has one set of slots (channel) so putting it in a diffrent channel isnt posible. Also my mobo does support a max of 16 gb
