I've been reading through so many threads, but now I think I'm more confused then I was..? I have a 2.16 C2D 15.4 Glossy.. I want to max out my ram.. so here are some questions. #1. The 1GB that comes with the machine: Is that 1x1GB? I just need to buy a 1x2GB, right? (EDIT: Found this answer, its 2x512 :GRR: ) #2. Anyone know the latency of the Apple factory RAM so I can match it? #3. What is the ideal setup for Dual Channel? What needs to match the factory chip to keep dual channel? Sorry for the redundant stupid questions. The more threads I read, the more they contradict themselves..
