No you get NO BOOST IN PERFORMANCE! Wow, the marketing is really working on you guys. Matched pairs is marketing BS. Sure they are the same type, same batch same speed etc etc. You can get the SAME thing by buying 2 single identical sticks. It is cheaper this way and will make ZERO difference. We do not overclock our macs so it makes NO DIFFERENCE WHATSOEVER. Just get 2 identical sticks (size, speed, make etc) and you will be fine.
I think the intent of the original question was -- can a 1 Gb and a 2 Gb module be considered a matched pair for the purposes of enabling Dual Channel memory access -- and the answer is no.
