I have two 512 sticks in my mobo right now. I want 2 gigs total. Should I get a single gigabyte stick (to run in single channel) or two more 512 sticks and run at 2T? Which is the biggest performance hit? Additionally if I do get the 1 GB stick, my current 512s will still run in dual channel at full speed, right? Though I think I know what's going on, memory isn't my forte so if someone could explain what happens if I put in 4x512 sticks, that would be appreciated. I have to set command rate to 2T to get 4x512 sticks, correct? I have a Winchester 90nm 3500+ CPU.
