Depends on the Chipset. Some memory controllers require matched pairs, some don't, but for performance reasons you normally use matched pairs with identical capacity and timing. If the chipset supports dual channel & you install matched pairs (in the correct sockets), then the controller will overlap memory access to gain speed (x2 at best, i.e. memory bandwidth is doubled). This is why a lot of memory is sold in pairs - sometimes its better to buy 2 x 2Gb DIMMs rather than 1 x 4Gb etc. When I say "pairs", I mean exactly identical in size, model, bus speed, timing etc. Just using, say, any 2 1Gb DIMMs and hoping will almost certainly not do the trick.
MBs that support this (pretty much all modern ones) will have an even number of memory sockets and often the sockets will be colour-coded in pairs.
Memory is cheap. Just do it!
