Upgrading to 2GB; what to purchase?

[firebird365]

I'm still using the computer in my sig, but I've decided to upgrade to 2GB of RAM. I don't really understand the principle behind Dual Channel (I read the FAQ, but perhaps I'm not dedicating enough time to grasp the concepts).

Anyway, I currently have 2x512MB in my machine. If I purchased the same sticks of memory and upped it to 4x512MB, would I notice any significant difference than if I instead bought 2x1GB sticks?

You would notice a difference, but i wouldn't say significant, more like slightly.

I see; and would the performance difference between 2GB and 1GB would make this negligible?

The only reason your system might be any faster with more RAM is because you won't need as much of a swap file. Besides the HD doing less work, things will load faster overall. However, raw performace will not be affected.

Alright, that makes sense. Thanks for the help.
