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

no... u dint understand my question... i was asking... in which case performance wud be better...??
case 1: if 1 use 2 sticks of 512 MB DDR2 RAM

or

case 2: if i use 1 stick of 1GB

in both cases total ram will b 1 gb... but someone told me use 2 sticks of 512MB i.e. dual channel and performance wud improve...

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
