Home is everywhere and nowhere.
So I have the latest (late 2012) iMAC 27 inches.
I'm a step away from well ordering, but I need help in knowing which of these would be compatible for my iMAC help http://www.wiredsystems.com/store/computer-components/memory.html?capacity=108&dir=asc&manufacturer=95&memory_speed=122&order=price

I currently have 12GB and I intend to add one more 4GB to make it 16 GB
It's always better to install RAM in pairs, you now seem to have 1 X 8 + 1 X 4 or 3 X 4 GB.
Best way is to buy them in pairs of the same brand.

+1 to everything said here.

Just to add that Kingston (which is what you searched for on the vendor site) has similar functionality on their own web site. I agree that you should use the same manufacturer and ideally the same exact part # as the other 4GB stick that was added to get from 8GB to 12GB.

Thanks for all your inputs. Yes I understand that.

I currently have 3 4GBs on my iMac which totals to 12GB. Now the last4Gb was a kingston RAM which is why I am adding another 4GB kingston RAM to make it to 16GB (which would suffice to me) but I am just a little confused as to which RAM to get from the list I've provided through that link above. Anyone?

You didn't state the part number for the existing 4GB Kingston stick but if I had to pick from the options in the link I'd say "Kingston 4GB 1600MHz DDR3 Non-ECC CL11 SODIMM". That one meets the basic criteria.

That said, if it were me, I'd want to know for sure. Your best bet is to find out what you installed previously. If you don't have records of it, you could just pull it out and look at the markings. The part number should be on a sticker on the RAM module.
