I have 512 at the moment and wish to add another gigabyte to it. I've heard of the dual channel RAM also. I'm guessing mine supports this because in the manual it has a picture of my computer inside (layout), it has two seperate Channels named 'A' and 'B', different colours and two slots for each channel.
So I want to make my RAM total 1.5GB, my motherboard is here;
Currently there are 2 256MB sticks, in the first two slots (so Channel A slot 1 and Channel B slot 1). How should I make this into 1.5GB? Two more 512MB sticks into the other two slots?
