My memory upgrade finally arrived, after more than two weeks. Mail from US to Canada is typically slow, but it sailed through Canada Customs without incurring any additional charges, so I'm not complaining.

Anyway, I recall seeing somewhere, some advice to install the smaller memory card in a certain position, but I don't remember where I saw it, and the installation video on the OWC site makes no mention of this. So, I figured that I'd just stick them in arbitrary positions since I couldn't imagine it causing any physical damage. When I fired up the computer, it recognized the full 6GB, and so I left things where they are.

I'm still curious though. Is there a preferred arrangement when using two different size memory cards?
