Hello, everyone. I'm a member of my school's newspaper staff and, because we work with Macs, I usually end up being the one that has to do most of the tech stuff. Anyway, a lot of our machines are outdated. About three of them are strawberry iMacs (Rev D, I think. They have 333MHz each.), a dual 800 PowerMac G4, and two other PowerMacs that I'm not completely sure about what their specs are. Anyway, what we're trying to do is install enough RAM into each computer to have them run OS X and allow us to switch from Quark XPress (Version 3.33, for god's sake.) to InDesign. A friend of mine sold us two 256 MB RAM modules to install onto these computers. I followed the RAM installation instructions on apple.com (http://docs.info.apple.com/article.html?artnum=43012 and http://docs.info.apple.com/article.html?artnum=43013) and only one module fit in one computer that way. (So I installed one module in two sepearete iMacs.) The other slot was occupied by the factory-installed RAM, but the modules my friend sold me didn't fit into those slots anyway. Anyway, after going through all of this, I put the Macs back together and turned them on. The problem is, they only seem to recognize 160 MB of the RAM! Does anyone know what the problem might be? I'd really appreciate any help. Thank you.
