Can you use DDR 256 mb memory and DDR 1GB memory on motherboard?

Answer:
What memory your motherboard can use will depend entirely on your motherboard. There is no way for someone to answer a generic question like this.

I can add a personal note that I did upgrade my dad's laptop to contain one 1GB stick as well as the 512MB it came with. Of course, I have no idea what motherboard it has (or even what manufacturer it is).
