Hi all, I want to upgrade memory in my Mac Pro early 2009 8-core. I was thinking a triple channel configuration and wanted to buy Kingston KTA-MP1066K3/12 x 2, so I'd end up with 24 GB. But to be sure, I did a systems check on the Kingston site and this particular memory isn't on the resulting list. So now I'm in doubt. Can I use this or do I really need the -more expensive- KTA-MP1066K4/16 banks that are on the list? Thanks!
