It’s up to the user/RAM purchaser to know which DIMMs would fit(*), and then just buy them without using the Advisor Tool. It’s a bit more work, but works just fine as long as the merchandise is in stock. (*) added
Nope; it doesn't work!
When I researched my original post I searched Crucial's website for DIMMs meeting the specs I was looking for, and the 4GB item didn't turn up. (My bad for not mentioning that.)
The DIMMs at issue, mine and Bob_00001's, apparently don't exist for
any reason other than to upgrade Macs beyond Apple's specs and
unless you specifically ask for them, so you
must specifically ask for them. (Crucial ultimately gave me the part number and told me I could order it..."
but it may not work" [
].)
It's a shame that Crucial, for whatever reason, is screwing customers who prefer
their DIMMs and so, for want of searching, are left unaware that the upgrades in question exist.
(*) "Above-spec" RAM is a pretty esoteric topic, and I suspect that many/most users who are aware that their RAM can be upgraded remain unaware of it
unless they learn about it from a vendor.
