So a Santa Rosa notebook with 64-bit OS and 64-bit CPU

I have a C2D notebook and Vista 64-bit, but only get 3GB apparently because the CHIPSET is only 32-bit. Just double checking that Santa Rosa should eliminate that problem.

yes Santa Rosa fully supports 4GB of ram. for example, you can get a MacBook Pro with 4GB of ram because it now has the Santa Rosa chipset.
