It's my understanding that the titanium powerbooks do not support over 1GB of RAM (two 512MB chips). I'm not sure if there are PC133 SO-DIMMs that meet Apple's spec that are over 512MB in size, or if it's even possible, but take, for example, the Aluminum Powerbooks... Apple says the 12" "supports up to 640MB." However, there are already two companies that well a 1GB module for the 12" powerbook: <http://www.dsp-memory.de/1gb/> and <http://www.dallasmemory.com>. The former is in Germany and has a picture of the 12" running with a 1024MB DIMM in available slot. Apple's Powerbook 17" Developer Notes also says that for each slot, "1 GB is a theoretical max and is reserved for future expansion," giving it an actual memory maximum of 2GB!! It's just a matter of time until 1GB PC2700 SO-DIMMs start getting manufactured. But as for the tibook, I believe it's unlikely, but who knows. Benn
