So I just got ahold of an old e-Machine (Model EL1600) with 1GB of 
memory. I was going to install CEntOS on it and try to run VirtualBox 
for other OS'es. I am curious to know if I have to stick with the 2GB 
"max" the specs say the machine can take or if its possible to install a 
4GB module that is designed the same? In other words I have seen 2GB DDR 
PC2700 memory that will fit the casing and work, but I have ALSO seen 
4GB DDR PC6400 memory modules with the same number of pins (240) will 
this work? I would want to have as much memory in there that will allow 
the VirtualBox to run smoothly.....any help would be appreciated!
