This mobo is single channel only, so does that mean a slower 1 gig stick would be better than two faster 512mb sticks? However, lot of people swear that low latency 2-2-2-x is what you need for all A64 setups. Unfortunately, I haven't seen anything close to that in one gig RAM sticks so I'm not sure what to get. I'm also looking toward the future when I may want to upgrade to 3gig memory. Rather than fleabay the two 512mb sticks it would be easier to just buy two more 1 gig sticks. What should I do? One stick or two?
