What is the maximum RAM that the board in the 2011 21" iMac can take?

History

On intel.com the processor in my machine the i5-2400S is listed as being able to support 32 GB of RAM. Can the board in the iMac

support that much?

Everymac has the maximum listed as 16 GB: http://www.everymac.com/systems/apple/im...

By default, 4 GB of RAM is installed as two 2 GB SO-DIMM modules. Two slots free. This model supports four 4 GB modules -- one in each slot for a maximum of 16 GB of memory.

Hi Mayer, the Everymac website says

"Officially, this model supports four 4 GB modules -- one in each slot for a maximum of 16 GB of memory. However, third-parties have discovered that it actually will support 32 GB of memory using four 8 GB modules."

what do you think? is the 32 GB correct info?

Update

Daniel Shugert, where did you buy the 2x8gb chips? do they have an specification for Mac? i thing something related to Mhz speed i guess. Cheers.

i have 20gb installed. the stock 2x2gb and an additional 2x8gb chips

i got them here: http://www.crucial.com/store/listparts.a... they're now almost half what i paid for them. may just have to grab another couple of sets and bump the iMac up to 32 and the i5 mac mini we have up to 16.
