Your iMac has four RAM slots and will take 32GB.

There are two RAM trays with a slot on either side for a total of four slots, but you need to confirm the exact model that you have.

Thanks guys, i see the two slots and didn't see that they held four. so thanks How do i find out what model i have? its a 27' 2011 When i check the the specifications it says Configurable to 16GB, only at the Apple Online Store. Does this mean i can only put in 4 x 4gb cards and no more? i was told before it will only take 16gb? Thanks again for your help
Apple only tested that computer with 16GB, but it can use 32GB.

Select About This Mac from the Apple menu. Depending on what OS X version you have, the info display will vary, but generally the first summary screen will be in the format of "iMac 27" (Late 2011)" or such. If you then click on the System Report button, Hardware Overview will display a ModelIdentifier in the format of "Mac mini6,2" but for your Mac.
II put his info into Mactracker.app to get a confirmation of the highest supported RAM level or OS X version. Or just go to reputable store site to get get help with exactly what type of RAM you need. I've used OWC (Other World Computing) and Newegg for many years now, without any issues. Don't be tempted to use eBay or other cheap sources - you're asking for problems.
Good luck!
