Q: Does new OS allow my iMac to take more RAM

Hi

I have an iMac 2.66Ghz 24" (early 2009)

From this article I have always understood that I am limited to a max of 8GB Ram (2 x 4GB sticks)

I started off on Snow Leopard and am now on Mountain Lion

Someone told me recently that the move to Mountain Lion has enabled my iMac to now take a maximum 16GB Ram (2 x 8GB sticks). I am wary to act on this and buy new memory as the Apple support article implies it is still limited to 8GB. But I woudl really like to upgrade to 16Gb if it will work.

Has anyone else tried to increase over 8GB with this model?

Any thoughts from the community woudl be greatly appreciated.

Thanks
