Will it fit (specifix RAM on iMac)?

Cheers!

I have an iMac 27" mid 2010 with Intel i7 2.93Ghz and MacOS 10.9. For now it have 8GB stock 4x2GB RAM but I want install at least 16GB+ RAM.

All official documents and data-sheets (especially Intel's chipset data-sheet) tells me that I can't install more than 16GB RAM with 4x4GB plates. But experience of all other users tell me that I can successfully install up to 32GB RAM with help of 8GB plates. Who is right?

I want to install 2x8GB of this Kingston: KVR1333D3S9/8G with 2x2GB of stock memory and get 20GB in total (smth like this this).

So, will it fit and work?
