I have a 7600 I'd like to put a gb of ram in. Can I use PC100 168pin ram or does it have to be something special like what is at everymac.com for it? I really don't want to spend $25 for a stick of 128. I like the idea of spending $15 for one though at geeks.com, I just need to make sure it will work. btw, this computer is going to be recieving a sonnet 800mhz upgrade card as well and run some variation of OSX, not sure what one yet.
