Maximum Memory upgrade 27" iMac i5

Hello!

I have recently bought a 27" iMac with the i5, 6970M vid card and 4gB of DDR3 with the intention of maxing out the RAM (after-market). I have seen some conflicting information so I'm wondering if someone can confirm if I can, in fact, add 4 8gB sticks to get to 32 gB? I know there are 4 slots, but are there any limitations I may not be aware of?

Help appreciated!

 

Thanks! I was fairly sure, but wanted to be 100% before ordering it (about $400 from corsair). Def expensive, but a hell of a lot cheaper than 16 from Apple.

Would you recommend the same 1333 DDR3 that Apple puts in it?

Thanks!
