Adding RAM to an iMAC Mid-2011-27" My iMac still has the original 2GB of RAM in the top two slots. Can I replace those top-slot RAMs with new 4GB RAM DIMMS at the same time I add two 4GB DIMMS to the now open bottom slots? Or can I only add the 8GB of new RAM to the bottom slots. Thanks

Assuming they are correct for your iMac, yes.

You didn't say which iMac but it looks like a 2015 5K. Both OWC and Crucial sell memory upgrades for your iMac.

it really will work if I add two 8 Gb blocks to two blocks of 4 Gb each (=24 Gb total)?

Thank you! I doubt a bit whether it fits or not? Apple Support reccomends memory for my MAC as "PC3-14900 DDR3". I found a specification in the store with some extra appendixes.: PC3L-14900S DDR3L

A couple things, that memory is for a Late 2015 iMac. And the other thing is, it's some generic memory I've never heard of. Last, I would never buy memory from ebay.
