I recently bought a Wallstreet (300MHz) off of eBay and it has 9.2.2 installed as well as 192MB ram. As I want to upgrade to OS X, I decided to buy 2 256MB ram modules to use in it and had a friend help install them in the top and bottom slots. The problem is that once we turned the Wallstreet back on, it only recognised 256MB of ram. We were both confused and I was wondering if 9.2.2 will only recognise that much or whether one/both of the Ram modules aren't fully compatible? Would OS X recognise the full 512? Thanks, C.
