    This all depends on what hardware (motherboard) configuration you use. If you run 1 stick of memory, this cannot be a dual channel configuration. Dual means 2. It is also nice to have matched pairs of memory in Dual Channel. It doesn't matter if you use 2 512MB sticks or 2 1GB sticks, or even 2 2GB sticks in Dual Channel. Remember it's your motherboard that determins the best Dual Channel setup

    2 sticks of matched (twin) 512mb will run faster in dual channel versus 1gb of standard memory. About 40% faster on average.

    One more time, on a dual channel motherboard:

    2 matched 512MB sticks, would out perform a single 1GB stick of memory
