I was able to install 1.5 gigs of ram. I tried to upgrade to 2 gigs, but the computer would not recognize it.
Vista may be programmed to run the original amount of ram that was in the machine, also a suggestion is to down grade vista to xp, vista is nothing but aggravation and windows 7 is even worse, there are way to many bugs that haven't been solved.

The maximum RAM that Windows Vista Ultimate can recognise is 4GB, as long as you have the 32-bit edition. If a 64-bit edition is being run then up to 12 GB RAM can be supported.
