Mid 2010 iMac 27 inch. Each slot 2 G ram. Can I replace 2 of the 2Gs with 2 8 Gs? or do I need to keep all four slots the same?
I have a mid 2010 iMac 27 inch with each of the four slots containing a 2 Gig DDR3 1333 PC3-10600 card. I need to upgrade memory for Aperture. Always running out. Can I replace 2 of the cards with 2 of the same cards in 8 Gig? Or, do I need to replace all four together to keep them the same?
