...and it doesn't work. The thing is I bought it from a seller, and he seems to be reputable, so what should I do with it? Should I call Apple? Contact the manufacturer of the ram (I'm trying to find out who it is) or just forget it? Basically I started it up with the stick in the slot, it gives me a wierd sort of grainy start up noise, then just a beeping sound... and it goes back to sleep. Thanks in advance for help. I'd be willing to answer any questions anyone asks.
