I'm struggling to find data on whether it can specifically use 2x 8GB RAM sticks, though your own experiments would seem to say it cannot & that its maximum configuration would be 4x 4GB sticks. Thank you for providing the updated information - however, as I suspected, that is one of the few iMacs from that period that cannot take more than 16GB RAM.

Result: Can boot into system perfectly fine, crashes when perform heavy duty tasks or run Rember RAM testing. I did some experientment with the 4 RAM slots and combinations, see below: I have attached two photos that show the RAM seats and crash screen.ĭo you think there's any problems with the RAM I just bought or the way I installed them? Please let me know what you think? The system boots perfectly fine, but when I perform heavy duty tasks or run Rember memory test app, it completely crashes. So right now the memory seats are two 2 GB original RAM + two 8 GB Crucial RAM. The specification meets this iMac model's requirement, and it has nice ratings.
My 2010 27" iMac just received a RAM upgrade: I bought a 16 GB RAM kit by Crucial on amazon.
