I want to add more memory to my late 2011 iMac 27inch. I have 8GB from the factory and want to add 8GB more. There are now 2 4GB cards installed, only if i want 16GB do i have to replace all the cards or just add 8GB more?
I want to install 2 4GB kingston KTA-MB1333K2/8G.

You will need to add 2 more of 4GB... Or like I would do and replace the ones in the computer now with new ones, to ensure all the ram matches...

Ideally, you want your RAM to have the exact same model and brand. This will guarantee that you get the most performance out of your RAM. However it's not necessarily a requirement. It is technically possible to mix-and-match different kinds of RAM. However, keep in mind that your computer is only a strong as its weakest link. A slower RAM module will cripple the faster ones. There's also a slight chance that your RAM sticks will not want to play nicely with each other. Most likely however, you shouldn't have any real problems.
