Can anyone help me understand if I would be better off with 3GB RAM or 2GB RAM in a new Mac Mini that is arrving tomorrow? (1.83Ghz Core 2 Duo). My limited understanding was that 2GB was the max and that matched pairs of RAM were required because the mini's "interleave." However, it seems that 3GB is an option but whether 2GB or 3GB would be better may be user / use specific. This is used in an entertainment center to drive videos to a 42" HDTV and music through a receiver. Front Row runs often, iTunes is always open, iPhoto is often open, movies play often, EyeTV records and plays OTA HDTV programs. Safari runs sometimes. Mail runs less. It's an entertainment unit so little else runs. Does anyone know if this would be better serverd by 2GB or 3GB? Thanks. mjc As further background where my explanations are deficient: OWC is selling a 3GB RAM kit with an interesting discussion the benefits of pairing 2GB versus the brute force of 3GB unpaired. They offer a comparison of paired versus unpaired RAM in a macbook with varying results, depending upon the test.

And apps like Aperture and Photoshop can certainly use the extra memory afforded by the 3GB config." November 15, 2006.
