Maximum memory for 2011 iMac I just bought an iMac and want to max out the memory on the machine. I have received two conflicting answers to my question so I'm bringing it to the community.

Can I install 4 8GB memory chips for a total of 32GB? The technical specs say it supports up to 16GB (4x4GB) but it hasn't been updated since May 2011 and was wonder if a firmware update allows it to support my proposed configuration.

The iMac has an i7 processor.
If you have the 27" iMac MacTracker says it supports up to 32GB, even though Apple only says it supports 16GB. The 21.5" iMac can only support 8GB either way. OWC, a reputable memory retailer, started selling 32GB upgrade kits for the 2011 iMac last year.
