Hi all!I was considering to acquire 512mb to 1GB of RAM to my machine... Wich ASUS motherboard would you suggest me for this purpose??? Can I purchase any kind of RAM and just fill up the slots, or each motherboard just accepts one specific kind of RAM?? And finally, what is the difference between a PC3200 and a PC2100 based memory???Thanks,Lucas.

PC3200 supports a motherboard front side bus speed of 400Mhz. It is considerably faster than PC2100. I would not think of buying anything less than PC3200 nowdays, unless you are adding to existing memory to an existing motherboard, in which case you probably want to get an exact match (brand name, speed, and memory version). Mixing and matching memory brands and speeds can yield very bad results.
