I successfully installed the 64 bit version of Ubuntu 12.04 last evening.

I have "DDR2 Synchronous 533 MHz" installed now, two 1GB sticks and two 
512 MB sticks. One of these days I'll see if I can find some more 1GB 
sticks. I did a bit of web searching and see on Wikipedia 
(https://en.wikipedia.org/wiki/DDR2_SDRAM) that I can mix memory with 
different speed ratings, but that the motherboard will probably run the 
higher rated memory at the lower speed. Is this something to be avoided?

Indeed. I've been fooling with Kdenlive (video editing program) and had 
it installed on both machines. I ran into a shortage of memory issue on 
the machine with only 3GB that wasn't a problem on the machine with 4GB.

Thanks for the insights.
