I now have 4GB memory, but I am thinking of increasing this. Before doing anhything, I'd appreciate some clarification on the following:


Memory specifications

These iMac models have these memory specifications:


Number of memory slots4
Base memory4 GB (but is configured to order)
Maximum memory16 GB
Note: For the iMac (Late 2009) models, you can use 2 GB or 4 GB RAM SO-DIMMs of 1066 MHz DDR3 SDRAM in each slot. For the iMac (Mid 2010) and iMac (Mid 2011) models, use 2 GB or 4 GB RAM SO-DIMMs of 1333 MHz DDR3 SDRAM in each slot.


Does this mean that in order to obtain the maximum memory of 16 GB I would have to remove the two memory chips that came with the computer and install 4GB chips in each of the four slots that then became available?
