Newbie question about memory

[Redoth]

If I buy a 2gb x3 set of memory, and then buy another 2gb x 3 set of that SAME memory, can I use them both, for a total of 12 GB, in the same machine? Or must I purchase, say, a set of 2gb x 6, or 4gb x 3? (I am thinking of triple channel ddr3 here.)

You can use 2 sets of the same brand and speed. You don't need one big matching set.
