Question: add the memories to my iMac
First, I apologize for my bad English.
I have some query about buying and add the memories to my iMac.
My iMac: 21.5-inch, mid 2011, 2.5GHz intel core i5.
1. Please, advise me on a good brand, I buy the memory from them.
2. Can I install 8 giga per one slot? I have read a note about this topic, on this web.
NOTE: The 2011 iMac is built with the Intel Core i5 Processor and has a Thunderbolt port. It has four memory sockets which can be upgraded to 32GBs maximum memory. Apple originally listed 16GB (4 x 4GB) as the maximum memory but 8GB modules have since been tested and 32GB (4 x 8GB) is the actual maximum memory. Apple recommends two modules of the same size be installed for maximum performance.
3. Can I diversify (the size) of the memory and (the production company) between the apertures? like i add 8giga card with 2giga card, or add the new memories to old ones.
4. How can I take advantage of the memories which I do not want, Can I send them to you, in return for memories or other supplies?
