I was very happy to expand my 2.16 Ghz MacBook Pro to 4 gigs from the Apple
stated 2 Gig max.
Turns out my very specific model chipset supports a full 4 gigs, same era
models of same laptop with different chipset only support 3 gig.
Breathed at least another year of life into that laptop... Which is good,
because I sprung for a new battery last year.
