spinning beachballs, and I just upped to 4 gigs of RAM?

[Racer X]

you know, I don't know how to check that. I ordered a pair from OWC for a MBP.

Should be no problem then, but if you go to the System Profiler it should be able to tell you if the RAM is interleaved.

the memory pane shows 2 2 gig sticks, and status OK, but I would assume somewhere it would show interleaved. I checked each stick's sub-pane, and nothing there either.

I'm not sure then. Maybe TechTool or something like that would say, but it's probably not the root cause anyway.
