Product Notes:

The unofficial maximum for the Apple iMac8,1 is 6GB; using a combination of 4GB+2GB upgrades. There are discussions of owners upgrading to 8GB using 2x4GB. However in our testing we have found the iMac will slow down when the RAM exceeds 6GB. Reference: https://discussions.apple.com/thread/4884412?start=0&tstart=0
