Sorry for such a newbie question, I know that dual channel ram needs to be installed in pairs but..... I started with 512mb (2 x 256mb) of ddr pc3200 ram....I bought a stick of 512, and I plan on buying another stick of 512mb. My motherboard supports 2GB of ram. For the time being, I guess my system is running in single channel mode? Now would I get the same performance from 512mb running in dual channel, as I would from 1GB running in single channel? I don't feel like there's much of difference in speed. I feel like I should have just waited and bought the 2 sticks of 512mb together. Would love to hear some feedback! Thanks.
