    Theres a downstairs iMac that has 4gb RAM inside running el capitan , if i open it and take out one of the slots of ram and replace it with different stick of ram leaving it with 3gb ram , what will happen when i turn the computer back on.

    Why do you expect that something particular should happen by doing that? :confused::rolleyes:

    The Activity Monitor Memory Pressure graph will likely more easily turn yellow/red than before with 4GB installed. When it does that you may notice it also swaps to disk more often, that may give you beachballs as I assume you have a normal HDD installed which are slooow when swapping.

    But if you only use it for light web browsing and email you may not notice any difference.
