Hi all, I currently have 2 x 512MB RAM in my 1.25GHz USB 2 eMac, and Leopard is kinda laggy on it. I want to get 2 x 1 GB, but am not sure what RAM to buy. I know I can look for PC2700 333MHz SDRAM, but was wondering if newer RAM (DDR2, etc.) is compatible. Sometimes older slower RAM is more expensive since it's no longer made. I just want to find the cheapest upgrade path, if I can get additional performance gains that would be icing on the cake. Thanks for any help! EDIT- I just found on Wikipedia that DDR2 is not backwards compatible with DDR, and they also have a different pin configuration. So I assume I need to search for DDR desktop RAM?
