    Mac Pro 2008 RAM upgrade
    I have mac pro early 2008 with 4GB ram (1GBx2 + 2GBx1).
    Now I'm thinking of an upgrade. Ram modules for this model are sold only in pairs. The question is do I have to dump the 2GB module that is already installed if i bought 2GBx2 or 4GBx2 for instance? or will it work?

    iMac i5 2.7GHz, 16GB memory, OS 10.11.1.
    No. Pop in the new memory according to the manual instructions, with the older memory in the correct Riser.
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!
