Yeah, many of the Macs are capable of supporting more Ram than Apple "recommend"........very much akin to Meridian and disk size in the MD600 for example

MacTracker from the App store is a very useful app for telling you what your Mac can actually support in real life.......and sites like Crucial and others will also tell you what you Mac can support

Care sometimes needs to be taken, as the Mac may be able to support higher capacities in some slots than others.......leading to some "weird" combinations of 6Gb and 12Gb being the max possible.....again that app and the sites will help with that info
